Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Monkey's Audio Source Code +Readme
+(last updated July 7, 2002)

+

Introduction

+

First off, just to be clear, you have to fully +agree with the included license agreement before using / viewing any of the +included materials.  The big points are that you can't steal code or try to +make money with it (without permission) and that you have to submit changes and +improvements back to the Monkey's Audio project.  With that out of the way, +I'm hoping that by releasing the source code, we'll be able to work together to +make Monkey's Audio better.  Please direct any suggestions or improvements +to the Monkey's Audio developer's forum or to me personally when appropriate. +(email @ monkeysaudio.com)  And thank you for taking the time to help.

The Monkey's Audio format is not +"finalized".  In fact, the compression / decompression engines +are continually being improved.  This is what makes MAC fun to work on, and +it's what makes progress possible.  I realize that this can be a pain for +3rd party developers, but it's the only way to avoid stagnation.  So, you +can not hard code Monkey's Audio support and expect it to work with the newest +versions of MAC forever.  Either use a DLL or else accept that you'll have +to re-link to MACLib once in a while.

+

Things that it'd be great if you worked on

+

1. It would be nice to have makefiles for gcc +or any other compilers that people commonly use.

+

2. Pour through the code and look for bone-head +maneuvers.

+

3. Submit any necessary changes for +cross-platform compilation. 

+

4. XMMS, Lame DLL, PocketPC, etc. plugins / +implementations.

+

5. A console front-end that doesn't suck. (more +options, etc.)  Also, don't worry about maintaining compatibility with the +current parameter passing scheme -- just use whatever makes sense.

+

Tips for building MACLib outside of Windows

+

1. in "Shared/All.h" do this:

+
    +
  • #define BUILD_CROSS_PLATFORM
    • +
  • look through "Shared/All.h" and + "Shared/NoWindows.h" to make sure all the defines are acceptable
    • +
+

2. You need to use NASM to build the assembly +if you want it. (helps speed a lot)  Check out "MacLib/Assembly/..." +for more information.

+

Known non-Windows problems (help fixing them +would be great)

+

2. The macros PUMP_MESSAGE_LOOP, MESSAGEBOX, and a few others don't work.

If CStdString compiles on your Unix box, you +// can thank Scott for it. +// +// 2000-DEC-29 - Joldakowski noticed one overload of Insert failed to do +// range check as CString's does. Now fixed -- thanks! +// +// 2000-NOV-07 - Aaron pointed out that I was calling static member +// functions of char_traits via a temporary. This was not +// technically wrong, but it was unnecessary and caused +// problems for poor old buggy VC5. Thanks Aaron! +// +// 2000-JUL-11 - Joe Woodbury noted that the CString::Find docs don't match +// what the CString::Find code really ends up doing. I was +// trying to match the docs. Now I match the CString code +// - Joe also caught me truncating strings for GetBuffer() calls +// when the supplied length was less than the current length. +// +// 2000-MAY-25 - Better support for STLPORT's Standard library distribution +// - Got rid of the NSP macro - it interfered with Koenig lookup +// - Thanks to Joe Woodbury for catching a TrimLeft() bug that +// I introduced in January. Empty strings were not getting +// trimmed +// +// 2000-APR-17 - Thanks to Joe Vitaterna for pointing out that ReverseFind +// is supposed to be a const function. +// +// 2000-MAR-07 - Thanks to Ullrich Pollhne for catching a range bug in one +// of the overloads of assign. +// +// 2000-FEB-01 - You can now use CStdString on the Mac with CodeWarrior! +// Thanks to Todd Heckel for helping out with this. +// +// 2000-JAN-23 - Thanks to Jim Cline for pointing out how I could make the +// Trim() function more efficient. +// - Thanks to Jeff Kohn for prompting me to find and fix a typo +// in one of the addition operators that takes _bstr_t. +// - Got rid of the .CPP file - you only need StdString.h now! +// +// 1999-DEC-22 - Thanks to Greg Pickles for helping me identify a problem +// with my implementation of CStdString::FormatV in which +// resulting string might not be properly NULL terminated. +// +// 1999-DEC-06 - Chris Conti pointed yet another basic_string<> assignment +// bug that MS has not fixed. CStdString did nothing to fix +// it either but it does now! The bug was: create a string +// longer than 31 characters, get a pointer to it (via c_str()) +// and then assign that pointer to the original string object. +// The resulting string would be empty. Not with CStdString! +// +// 1999-OCT-06 - BufferSet was erasing the string even when it was merely +// supposed to shrink it. Fixed. Thanks to Chris Conti. +// - Some of the Q172398 fixes were not checking for assignment- +// to-self. Fixed. Thanks to Baptiste Lepilleur. +// +// 1999-AUG-20 - Improved Load() function to be more efficient by using +// SizeOfResource(). Thanks to Rich Zuris for this. +// - Corrected resource ID constructor, again thanks to Rich. +// - Fixed a bug that occurred with UNICODE characters above +// the first 255 ANSI ones. Thanks to Craig Watson. +// - Added missing overloads of TrimLeft() and TrimRight(). +// Thanks to Karim Ratib for pointing them out +// +// 1999-JUL-21 - Made all calls to GetBuf() with no args check length first. +// +// 1999-JUL-10 - Improved MFC/ATL independence of conversion macros +// - Added SS_NO_REFCOUNT macro to allow you to disable any +// reference-counting your basic_string<> impl. may do. +// - Improved ReleaseBuffer() to be as forgiving as CString. +// Thanks for Fan Xia for helping me find this and to +// Matthew Williams for pointing it out directly. +// +// 1999-JUL-06 - Thanks to Nigel Nunn for catching a very sneaky bug in +// ToLower/ToUpper. They should call GetBuf() instead of +// data() in order to ensure the changed string buffer is not +// reference-counted (in those implementations that refcount). +// +// 1999-JUL-01 - Added a true CString facade. Now you can use CStdString as +// a drop-in replacement for CString. If you find this useful, +// you can thank Chris Sells for finally convincing me to give +// in and implement it. +// - Changed operators << and >> (for MFC CArchive) to serialize +// EXACTLY as CString's do. So now you can send a CString out +// to a CArchive and later read it in as a CStdString. I have +// no idea why you would want to do this but you can. +// +// 1999-JUN-21 - Changed the CStdString class into the CStdStr template. +// - Fixed FormatV() to correctly decrement the loop counter. +// This was harmless bug but a bug nevertheless. Thanks to +// Chris (of Melbsys) for pointing it out +// - Changed Format() to try a normal stack-based array before +// using to _alloca(). +// - Updated the text conversion macros to properly use code +// pages and to fit in better in MFC/ATL builds. In other +// words, I copied Microsoft's conversion stuff again. +// - Added equivalents of CString::GetBuffer, GetBufferSetLength +// - new sscpy() replacement of CStdString::CopyString() +// - a Trim() function that combines TrimRight() and TrimLeft(). +// +// 1999-MAR-13 - Corrected the "NotSpace" functional object to use _istpace() +// instead of _isspace() Thanks to Dave Plummer for this. +// +// 1999-FEB-26 - Removed errant line (left over from testing) that #defined +// _MFC_VER. Thanks to John C Sipos for noticing this. +// +// 1999-FEB-03 - Fixed a bug in a rarely-used overload of operator+() that +// caused infinite recursion and stack overflow +// - Added member functions to simplify the process of +// persisting CStdStrings to/from DCOM IStream interfaces +// - Added functional objects (e.g. StdStringLessNoCase) that +// allow CStdStrings to be used as keys STL map objects with +// case-insensitive comparison +// - Added array indexing operators (i.e. operator[]). I +// originally assumed that these were unnecessary and would be +// inherited from basic_string. However, without them, Visual +// C++ complains about ambiguous overloads when you try to use +// them. Thanks to Julian Selman to pointing this out. +// +// 1998-FEB-?? - Added overloads of assign() function to completely account +// for Q172398 bug.

PREAMBLE + +The purpose of this License is to make a manual, textbook, or other +functional and useful document "free" in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +Secondarily, this License preserves for the author and publisher a way +to get credit for their work, while not being considered responsible +for modifications made by others. + +This License is a kind of "copyleft", which means that derivative +works of the document must themselves be free in the same sense. It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + + +1. APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The "Document", below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as "you". You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A "Modified Version" of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A "Secondary Section" is a named appendix or a front-matter section of +the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall subject +(or to related matters) and contains nothing that could fall directly +within that overall subject. (Thus, if the Document is in part a +textbook of mathematics, a Secondary Section may not explain any +mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The "Invariant Sections" are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The "Cover Texts" are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A "Transparent" copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not "Transparent" is called "Opaque". + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, LaTeX input format, SGML +or XML using a publicly available DTD, and standard-conforming simple +HTML, PostScript or PDF designed for human modification. Examples of +transparent image formats include PNG, XCF and JPG. Opaque formats +include proprietary formats that can be read and edited only by +proprietary word processors, SGML or XML for which the DTD and/or +processing tools are not generally available, and the +machine-generated HTML, PostScript or PDF produced by some word +processors for output purposes only. + +The "Title Page" means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, "Title Page" means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section "Entitled XYZ" means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as "Acknowledgements", +"Dedications", "Endorsements", or "History".) To "Preserve the Title" +of such a section when you modify the Document means that it remains a +section "Entitled XYZ" according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + + +2. VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + + +3. COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + + +4. MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +A. Use in the Title Page (and on the covers, if any) a title distinct + from that of the Document, and from those of previous versions + (which should, if there were any, be listed in the History section + of the Document). You may use the same title as a previous version + if the original publisher of that version gives permission. +B. List on the Title Page, as authors, one or more persons or entities + responsible for authorship of the modifications in the Modified + Version, together with at least five of the principal authors of the + Document (all of its principal authors, if it has fewer than five), + unless they release you from this requirement. +C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. +D. Preserve all the copyright notices of the Document. +E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. +F. Include, immediately after the copyright notices, a license notice + giving the public permission to use the Modified Version under the + terms of this License, in the form shown in the Addendum below. +G. Preserve in that license notice the full lists of Invariant Sections + and required Cover Texts given in the Document's license notice. +H. Include an unaltered copy of this License. +I. Preserve the section Entitled "History", Preserve its Title, and add + to it an item stating at least the title, year, new authors, and + publisher of the Modified Version as given on the Title Page. If + there is no section Entitled "History" in the Document, create one + stating the title, year, authors, and publisher of the Document as + given on its Title Page, then add an item describing the Modified + Version as stated in the previous sentence. +J. Preserve the network location, if any, given in the Document for + public access to a Transparent copy of the Document, and likewise + the network locations given in the Document for previous versions + it was based on. These may be placed in the "History" section. + You may omit a network location for a work that was published at + least four years before the Document itself, or if the original + publisher of the version it refers to gives permission. +K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section all + the substance and tone of each of the contributor acknowledgements + and/or dedications given therein. +L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section titles. +M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. +N. Do not retitle any existing section to be Entitled "Endorsements" + or to conflict in title with any Invariant Section. +O. Preserve any Warranty Disclaimers. + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled "Endorsements", provided it contains +nothing but endorsements of your Modified Version by various +parties--for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + + +5. COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled "History" +in the various original documents, forming one section Entitled +"History"; likewise combine any sections Entitled "Acknowledgements", +and any sections Entitled "Dedications". You must delete all sections +Entitled "Endorsements". + + +6. COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + + +7. AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an "aggregate" if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + + +8. TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled "Acknowledgements", +"Dedications", or "History", the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + + +9. TERMINATION + +You may not copy, modify, sublicense, or distribute the Document except +as expressly provided for under this License. Any other attempt to +copy, modify, sublicense or distribute the Document is void, and will +automatically terminate your rights under this License. However, +parties who have received copies, or rights, from you under this +License will not have their licenses terminated so long as such +parties remain in full compliance. + + +10. FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +http://www.gnu.org/copyleft/. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License "or any later version" applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. + + +ADDENDUM: How to use this License for your documents + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + + Copyright (c) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.2 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. + A copy of the license is included in the section entitled "GNU + Free Documentation License". + +If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, +replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with the + Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. + +If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + +If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of +free software license, such as the GNU General Public License, +to permit their use in free software. diff --git a/flac/COPYING.GPL b/flac/COPYING.GPL new file mode 100644 index 0000000..90df1ce --- /dev/null +++ b/flac/COPYING.GPL @@ -0,0 +1,340 @@ + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 Free Software Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices.

If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16.

See + + doc/html/index.html + +for full documentation. + +A brief description of the directory tree: + + doc/ the HTML documentation + include/ public include files for libFLAC and libFLAC++ + man/ the man page for `flac' + src/ the source code and private headers + test/ the test scripts + + +=============================================================================== +Prerequisites +=============================================================================== + +To build FLAC with support for Ogg FLAC you must have built and installed +libogg according to the specific instructions below. You must have +libogg 1.1.2 or greater, or there will be seeking problems with Ogg FLAC. + +If you are building on x86 and want the assembly optimizations, you will +need to have NASM >= 0.98.30 installed according to the specific instructions +below. + + +=============================================================================== +Note to embedded developers +=============================================================================== + +libFLAC has grown larger over time as more functionality has been +included, but much of it may be unnecessary for a particular embedded +implementation. Unused parts may be pruned by some simple editing of +configure.in and src/libFLAC/Makefile.am; the following dependency +graph shows which modules may be pruned without breaking things +further down: + +metadata.h + stream_decoder.h + format.h + +stream_encoder.h + stream_decoder.h + format.h + +stream_decoder.h + format.h + +In other words, for pure decoding applications, both the stream encoder +and metadata editing interfaces can be safely removed. + +There is a section dedicated to embedded use in the libFLAC API +HTML documentation (see doc/html/api/index.html). + +Also, there are several places in the libFLAC code with comments marked +with "OPT:" where a #define can be changed to enable code that might be +faster on a specific platform. Experimenting with these can yield faster +binaries. + + +=============================================================================== +Building in a GNU environment +=============================================================================== + +FLAC uses autoconf and libtool for configuring and building. +Better documentation for these will be forthcoming, but in +general, this should work: + +./configure && make && make check && make install + +The 'make check' step is optional; omit it to skip all the tests, +which can take several hours and use around 70-80 megs of disk space. +Even though it will stop with an explicit message on any failure, it +does print out a lot of stuff so you might want to capture the output +to a file if you're having a problem. Also, don't run 'make check' +as root because it confuses some of the tests. + +NOTE: Despite our best efforts it's entirely possible to have +problems when using older versions of autoconf, automake, or +libtool. If you have the latest versions and still can't get it +to work, see the next section on Makefile.lite. + +There are a few FLAC-specific arguments you can give to +`configure': + +--enable-debug : Builds everything with debug symbols and some +extra (and more verbose) error checking. + +--disable-asm-optimizations : Disables the compilation of the +assembly routines. Many routines have assembly versions for +speed and `configure' is pretty good about knowing what is +supported, but you can use this option to build only from the +C sources. May be necessary for building on OS X (Intel) + +--enable-sse : If you are building for an x86 CPU that supports +SSE instructions, you can enable some of the faster routines +if your operating system also supports SSE instructions. flac +can tell if the CPU supports the instructions but currently has +no way to test if the OS does, so if it does, you must pass +this argument to configure to use the SSE routines. If flac +crashes when built with this option you will have to go back and +configure without --enable-sse. Note that +--disable-asm-optimizations implies --disable-sse. + +--enable-local-xmms-plugin : Installs the FLAC XMMS plugin in +$HOME/.xmms/Plugins, instead of the global XMMS plugin area +(usually /usr/lib/xmms/Input). + +--with-ogg= +--with-xmms-prefix= +--with-libiconv-prefix= +Use these if you have these packages but configure can't find them. + +If you want to build completely from scratch (i.e. starting with just +configure.in and Makefile.am) you should be able to just run 'autogen.sh' +but make sure and read the comments in that file first. + + +=============================================================================== +Building with Makefile.lite +=============================================================================== + +There is a more lightweight build system for do-it-yourself-ers. +It is also useful if configure isn't working, which may be the +case since lately we've had some problems with different versions +of automake and libtool. The Makefile.lite system should work +on GNU systems with few or no adjustments. + +From the top level just 'make -f Makefile.lite'. You can +specify zero or one optional target from 'release', 'debug', +'test', or 'clean'. The default is 'release'. There is no +'install' target but everything you need will end up in the +obj/ directory. + +If you are not on an x86 system or you don't have nasm, you +may have to change the DEFINES in src/libFLAC/Makefile.lite. If +you don't have nasm, remove -DFLAC__HAS_NASM. If your target is +not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN. + + +=============================================================================== +Building with MSVC +=============================================================================== + +There are .dsp projects and a master FLAC.dsw workspace to build all +the libraries and executables with MSVC6. There are also .vcproj +projects and a master FLAC.sln solution to build all the libraries and +executables with VC++ 2005. + +Prerequisite: you must have the Ogg libraries installed as described +later. + +Prerequisite: you must have nasm installed, and nasmw.exe must be in +your PATH, or the path to nasmw.exe must be added to the list of +directories for executable files in the MSVC global options. + +MSVC6: +To build everything, run Developer Studio, do File|Open Workspace, +and open FLAC.dsw. Select "Build | Set active configuration..." +from the menu, then in the dialog, select "All - Win32 Release" (or +Debug if you prefer). Click "Ok" then hit F7 to build. + +VC++ 2005: +To build everything, run Visual Studio, do File|Open and open FLAC.sln. +From the dropdown in the toolbar, select "Release" instead of "Debug", +then hit F7 to build. + +Either way, this will build all libraries both statically (e.g. +obj\release\lib\libFLAC_static.lib) and as DLLs (e.g. +obj\release\lib\libFLAC.dll), and it will build all binaries, statically +linked (e.g. obj\release\bin\flac.exe). + +Everything will end up in the "obj" directory. DLLs and .exe files +are all that are needed and can be copied to an installation area and +added to the PATH. The plugins have to be copied to their appropriate +place in the player area. For Winamp2 this is \Plugins. + +By default the code is configured with Ogg support. Before building FLAC +you will need to get the Ogg source distribution +(see http://xiph.org/ogg/vorbis/download/), build ogg_static.lib (load and +build win32\ogg_static.dsp), copy ogg_static.lib into FLAC's +'obj\release\lib' directory, and copy the entire include\ogg tree into +FLAC's 'include' directory (so that there is an 'ogg' directory in FLAC's +'include' directory with the files ogg.h, os_types.h and config_types.h). + +If you want to build without Ogg support, instead edit all .dsp or +.vcproj files and remove any occurrences of "/D FLAC__HAS_OGG". + + +=============================================================================== +Building on Mac OS X +=============================================================================== + +If you have Fink or a recent version of OS X with the proper autotooles, +the GNU flow above should work. The Project Builder project has been +deprecated but we are working on replacing it with an Xcode equivalent. diff --git a/flac/all.dsp b/flac/all.dsp new file mode 100644 index 0000000..c85ef84 --- /dev/null +++ b/flac/all.dsp @@ -0,0 +1,67 @@ +# Microsoft Developer Studio Project File - Name="all" - Package Owner=<4> +# Microsoft Developer Studio Generated Build File, Format Version 6.00 +# ** DO NOT EDIT ** + +# TARGTYPE "Win32 (x86) Generic Project" 0x010a + +CFG=all - Win32 Debug +!MESSAGE This is not a valid makefile.

+ This is an informal changelog, a summary of changes in each release. (See also known bugs.) Particulary important for developers is the precise description of changes to the library interfaces. See also the porting guide for specific instructions on porting to newer versions of FLAC.
+ +
+ + + + FLAC 1.2.1 (17-Sep-2007) + +
+ +
    +
  • + General: +
      +
    • With the new --keep-foreign-metadata in flac, non-audio RIFF and AIFF chunks can be stored in FLAC files and recreated when decoding. This allows, among other, things support for archiving BWF files and other WAVE files from editing tools that preserves all the metadata.
      • +
    +
    • +
  • + FLAC format: +
      +
    • Specified 2 new APPLICATION metadata blocks for storing WAVE and AIFF chunks (for use with --keep-foreign-metadata in flac).
      • +
    • The lead-out track number for non-CDDA cuesheets now must be 255.
      • +
    +
    • +
  • + Ogg FLAC format: +
      +
    • This is not a format change, but changed default extension for Ogg FLAC from .ogg to .oga, according to new Xiph specification (SF #1762492).
      • +
    +
    • +
  • + flac: +
      +
    • Added a new option --no-utf8-convert which works like it does in metaflac (SF #973740).
      • +
    • Added a new option --keep-foreign-metadata which can save/restore RIFF and AIFF chunks to/from FLAC files (SF #363478).
      • +
    • Changed default extension for Ogg FLAC from .ogg to .oga, according to new Xiph specification (SF #1762492).
      • +
    • Fixed bug where using --replay-gain without any padding option caused only a small PADDING block to be created (SF #1760790).
      • +
    • Fixed bug where encoding from stdin on Windows could fail if WAVE/AIFF contained unknown chunks (SF #1776803).
      • +
    • Fixed bug where importing non-CDDA cuesheets would cause an invalid lead-out track number (SF #1764105).
      • +
    +
    • +
  • + metaflac: +
      +
    • Changed default extension for Ogg FLAC from .ogg to .oga, according to new Xiph specification (SF #1762492).
      • +
    • Fixed bug where importing non-CDDA cuesheets would cause an invalid lead-out track number (SF #1764105).

    • + libFLAC: +
        +
      • Added FLAC__metadata_simple_iterator_is_last()
        • +

        • +
      +
      • +

        • +
      • Added FLAC::Metadata::SimpleIterator::get_block_offset()
        • +
      • Added FLAC::Metadata::SimpleIterator::get_block_length()

    • +
+ +
+ + FLAC 1.2.0 (23-Jul-2007) + +
+ +
    +
  • + General: +
      +
    • Small encoding speedups for all modes.
      • +
    +
    • +
  • + FLAC format: +
      +
    • One of the reserved bits in the FLAC frame header has been assigned for future use; make sure to refer to the porting guide if you parse FLAC streams manually.
      • +
    +
    • +
  • + Ogg FLAC format: +
      +
    • (none)
      • +
    +
    • +
  • + flac: +
      +
    • Added runtime detection of SSE OS support for most operating systems.
      • +
    • Added a new undocumented option --ignore-chunk-sizes for ignoring the size of the 'data' chunk (WAVE) or 'SSND' chunk (AIFF). Can be used to encode files with bogus data sizes (e.g. with WAV files piped from foobar2000 to flac.exe as an external encoder). Use with caution: all subsequent data is treated as audio, so the data/SSND chunk must be the last or the following data/tags will be treated as audio and encoded.

      • +
    +
    • +
  • + libraries: +
      +
    • Added runtime detection of SSE OS support for most operating systems.
      • +

      • +
    +
    • +
  • + Interface changes (see also the porting guide for specific instructions on porting to FLAC 1.2.0): +
      +
    • + libFLAC: +
        +
      • Added FLAC__format_sample_rate_is_subset()
        • +
      +
      • +
    • + libFLAC++: +

    • +
+ +
+ + FLAC 1.1.4 (13-Feb-2007) + +
+ +
    +
  • + General: +
      +
    • Improved compression with no change to format or decrease in speed.
      • +
    • Encoding and decoding speedups for all modes. Encoding at -8 is twice as fast.
      • +
    +
    • +
  • + FLAC format: +
      +
    • (none)
      • +
    +
    • +
  • + Ogg FLAC format: +
      +
    • (none)
      • +
    +
    • +
  • + flac: +
      +
    • Improved compression with no change to format or decrease in speed.
      • +
    • Encoding and decoding speedups for all modes. Encoding at -8 is twice as fast.
      • +
    • Added a new option -w,--warnings-as-errors for treating all warnings as errors.
      • +
    • Allow --picture option to take only a filename, and have all other attributes extracted from the file itself.
      • +
    • Fixed a bug that caused suboptimal default compression settings in some locales (SF #1608883).
      • +
    • Fixed a bug where FLAC-to-FLAC transcoding of a corrupted FLAC file would truncate the transcoded file at the first error (SF #1615019).
      • +
    • Fixed a bug where using -F with FLAC-to-FLAC transcoding of a corrupted FLAC would have no effect (SF #1615391).
      • +
    • Fixed a bug where new PICTURE metadata blocks specified with --picture would not be transferred during FLAC-to-FLAC transcoding (SF #1627993).
      • +
    +
    • +
  • + metaflac: +
      +
    • Allow --import-picture-from option to take only a filename, and have all other attributes extracted from the file itself.
      • +
    +
    • +
  • + plugins: +
      +
    • Fixed a bug in the XMMS plugin where Ctrl-3 (file info) would cause a crash if the file did not exist (SF #1634941).
      • +
    +
    • +
  • + build system: +
      +
    • Fixed a makefile linkage bug with libogg (SF #1611414).
      • +
    • Added pkg-config files for libFLAC and libFLAC++ (SF #1647881).
      • +
    • Added --disable-ogg option for building without Ogg support even if libogg is installed (SF #1196996).
      • +
    +
    • +
  • + libraries: +
      +
    • Completely rewritten bitbuffer which uses native machine word size instead of bytes for dramatic speed improvements. The speedup should be most dramatic on CPUs with slower byte manipulation capability and big-endian machines.
      • +
    • Much faster Rice partition size estimation which greatly speeds encoding in higher modes.
      • +
    • Increased compression for all modes.
      • +
    • Reduced memory requirements for encoder and decoder.
      • +
    • Fixed a bug with default apodization settings that were erroneous in some locales (SF #1608883).
      • +
    +
    • +
  • + Interface changes: +
      +
    • + libFLAC: +
        +
      • (behavior only) FLAC__stream_encoder_set_metadata() now makes a copy of the "metadata" array of pointers (but still not copies of the objects themselves) so the client does not need to maintain its copy of the array after the call.
        • +
      +
      • +
    • + libFLAC++: +
        +
      • (none)
        • +
      +
      • +
    +
    • +
+ +
+ + FLAC 1.1.3 (27-Nov-2006) + +
+ +
    +
  • + General: +
      +
    • Improved compression with no impact on format or decoding speed.
      • +
    • Much better recovery for corrupted files
      • +
    • Better multichannel support
      • +
    • Large file (>2GB) support everywhere
      • +
    • flac now supports FLAC and Ogg FLAC as input to the encoder (e.g. can re-encode FLAC to FLAC) and preserve all the metadata like tags, etc.
      • +
    • New PICTURE metadata block for storing things like cover art, new --picture option to flac and --import-picture-from option to metaflac for importing pictures, new --export-picture-to option to metaflac for exporting pictures, and metadata API additions for searching for suitable pictures based on type, size and color constraints.
      • +
    • Support for new REPLAYGAIN_REFERENCE_LOUDNESS tag.
      • +
    • Fixed a bug in Ogg FLAC encoding where metadata was not being updated properly. Existing Ogg FLAC files should be recoded to fix up the metadata, e.g. flac -Vf -S 10s --ogg file.ogg
      • +
    • In the developer libraries, the interface has been simplfied by merging the three decoding layers into a single class; ditto for the encoders. Also, libOggFLAC has been merged into libFLAC and libOggFLAC++ has been merged into libFLAC++ so there is a single API supporting both native FLAC and Ogg FLAC.
      • +
    +
    • +
  • + FLAC format: +
      +
    • New PICTURE metadata block for storing things like cover art.
      • +
    • Speaker assignments and channel orders for 3-6 channels (see frame header).
      • +
    • Further restrictions on the FLAC subset when the sample rate is <=48kHz; in this case the maximum LPC order is now 12 and maximum blocksize is 4608. This is to further limit the processing and memory requirements for hardware implementations while not measurably affecting compression.
      • +
    +
    • +
  • + Ogg FLAC format: +
      +
    • (none)
      • +
    +
    • +
  • + flac: +
      +
    • Improved the -F option to allow decoding of FLAC files whose metadata is corrupted, and other kinds of severe corruption.
      • +
    • Encoder can now take FLAC and Ogg FLAC as input. The output FLAC file will have all the same metadata as the original unless overridden with options on the command line.
      • +
    • Encoder can now take WAVEFORMATEXTENSIBLE WAVE files as input; decoder will output WAVEFORMATEXTENSIBLE WAVE files when necessary to conform to the latest Microsoft specifications.
      • +
    • Now properly supports AIFF and WAVEFORMATEXTENSIBLE multichannel input, performing necessary channel reordering both for encoding and decoding. WAVEFORMATEXTENSIBLE channel mask is also saved to a tag on encoding and restored on decoding for situations when there is no natural mapping to FLAC channel assignments.
      • +
    • Expanded support for "odd" sample resolutions to WAVE and AIFF input; all resolutions from 4 to 24 bits-per-sample now supported for all input types.
      • +
    • Added a new option --tag-from-file for setting a tag from file (e.g. for importing a cuesheet as a tag).
      • +
    • Added a new option --picture for adding pictures.
      • +
    • Added a new option --apodization for specifying the window function(s) to be used in LPC analysis.
      • +
    • Added support for encoding from non-compressed AIFF-C (SF #1090933).
      • +
    • Importing of non-CDDA-compliant cuesheets now only issues a warning, not an error (see here).
      • +
    • MD5 comparison failures on decoding are now an error instead of a warning and will also return a non-zero exit code (SF #1493725).
      • +
    • The default padding size is now 8K, or 64K if the input audio stream is more than 20 minutes long.
      • +
    • Fixed a bug in cuesheet parsing where it would return an error if the last line of the cuesheet did not end with a newline.
      • +
    • Fixed a bug that caused a crash when -a and -t were used together (SF #1229481).
      • +
    • Fixed a bug with --sector-align where appended samples were not always totally silent (SF #1237707).
      • +
    • Fixed bugs with --sector-align and raw input files.
      • +
    • Fixed a bug printing out unknown AIFF subchunk names (SF #1267476).
      • +
    • Fixed a bug where WAVE files with "data" subchunks of size 0 where accepted (SF #1293830).
      • +
    • Fixed a bug where sync error at end-of-stream of truncated files was not being caught (SF #1244071).
      • +
    • Fixed a problem with filename parsing if file does not have extension but also has a . in the path (SF #1161916).
      • +
    • Fixed a problem with fractional-second parsing for --skip/--until in some locales (SF #1031043).
      • +
    • Increase progress report rate when -p and -e are used together (SF #1580122).
      • +
    +
    • +
  • + metaflac: +
      +
    • Added support for read-only operations on Ogg FLAC files.
      • +
    • Added a new option --set-tag-from-file for setting a tag from file (e.g. for importing a cuesheet as a tag).
      • +
    • Added a new option --import-picture-from for importing pictures.
      • +
    • Added a new option --export-picture-to for exporting pictures.
      • +
    • Added shorthand operation --remove-replay-gain for removing ReplayGain tags.
      • +
    • --export-cuesheet-to now properly specifies the FLAC file name (SF #1272825).
      • +
    • Importing of non-CDDA-compliant cuesheets now issues a warning.
      • +
    • Removed the following deprecated tag editing options; you should use the new option names shown instead: +
        +
      • Removed --show-vc-vendor; use --show-vendor-tag
        • +
      • Removed --show-vc-field; use --show-tag
        • +
      • Removed --remove-vc-all; use --remove-all-tags

        • +
      • Removed --set-vc-field; use --set-tag
        • +
      • Removed --import-vc-from; use --import-tags-from
        • +
      • Removed --export-vc-to; use --export-tags-to
        • +
      +
      • +
    • Disallow multiple input FLAC files when --import-tags-from=- is used (SF #1082577).
      • +
    +
    • +
  • + plugins: +
      +
    • When ReplayGain is on, if tags for the preferred kind of gain (album/track) are not in a stream, the other kind will be used.
      • +
    • Added ReplayGain info to file info box in XMMS plugin
      • +
    • Fixed UTF-8 decoder to disallow non-shortest-form and surrogate sequences (see here).
      • +
    +
    • +
  • + build system: +
      +
    • Added support for building on OS/2 with EMX (SF #1229495)
      • +
    • Added support for building with Borland C++ (SF #1599018)
      • +
    • Added a --disable-xmms-plugin option to configure to prevent building the XMMS plugin (SF #930494).
      • +
    • Added a --disable-doxygen-docs option to configure for disabling Doxygen-based API doc generation (SF #1365935).
      • +
    • Added a --disable-thorough-tests option to configure to do the basic library, stream, and tool tests in a reasonable time (SF #1077948).
      • +
    • Added large file support with AC_SYS_LARGEFILE; use --disable-largefile with configure to disable.
      • +
    +
    • +
  • + libraries: +
      +
    • Merged libOggFLAC into libFLAC; both formats are now supporte through the same API.
      • +
    • Merged libOggFLAC++ into libFLAC++; both formats are now supporte through the same API.
      • +
    • libFLAC and libFLAC++: Simplified encoder setup with new FLAC__stream_encoder_set_compression_level() function.
      • +
    • libFLAC: Improved compression with no impact on FLAC format or decoding time by adding a windowing stage before LPC analysis.
      • +
    • libFLAC: Fixed a bug where missing STREAMINFO fields (min/max framesize, total samples, MD5 sum) and seek point offsets were not getting rewritten back to Ogg FLAC file (SF #1338969).
      • +
    • libFLAC: Fixed a bug in cuesheet parsing where it would return an error if the last line of the cuesheet did not end with a newline.

      • The above two changes mean that when the decoder encounters what it thinks are unparseable frames from a future decoder, instead of returning a fatal error with the FLAC__STREAM_DECODER_UNPARSEABLE_STREAM state, it just calls the error callback with FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM and leaves the behavior up to the application.

+ + FLAC 1.1.2 (05-Feb-2005) + +
+ +
    +
  • + General: +
      +
    • Sped up decoding by a few percent overall.
      • +
    • Sped up encoding when not using LPC (i.e. when using flac options -0, -1, -2, or -l 0).
      • +
    • Fixed a decoding bug that could cause sync errors with some ID3v1-tagged FLAC files.
      • +
    • Added HTML documentation for metaflac.
      • +

    • New option --input-size to manually specify the input size when encoding raw samples from stdin.

      +
    • (none)
      • +
    +
    • +
  • + plugins: +
      +
    • Added support for HTTP streaming in XMMS plugin. NOTE: there is a bug in the XMMS mpg123 plugin that hijacks FLAC streams; to fix it you will need to add the '.flac' extension to the list of exceptions in Input/mpg123/mpg123.c:is_our_file() in the XMMS sources and recompile.

      +
    • (none)
      • +
    +
    • +
  • + libraries: +
      +
    • libFLAC: Sped up Rice block decoding in the bitbuffer, resulting in decoding speed gains of a few percent.
      • +
    • libFLAC: Sped up encoding when not using LPC (i.e. max_lpc_order == 0).
      • +
    • libFLAC: Trailing NUL characters maintained on Vorbis comment entries so they can be treated like C strings.
      • +
    • libFLAC: More FLAC tag (i.e. Vorbis comment) validation.
      • +
    • libFLAC: Fixed a bug in the logic that determines the frame or sample number in a frame header; the bug could cause sync errors with some ID3v1-tagged FLAC files.
      • +
    • libFLAC, libOggFLAC: Can now be compiled to use only integer instructions, including encoding. The decoder is almost completely integer anyway but there were a couple places that needed a fixed-point replacement. There is no fixed-point version of LPC analysis yet, so if libFLAC is compiled integer-only, the encoder will behave as if the max LPC order is 0 (i.e. used fixed predictors only). LPC decoding is supported in all cases as it always was integer-only.

      • Added FLAC__metadata_object_vorbiscomment_entry_to_name_value_pair()

        +
        • +
      • Changed the signature of FLAC::Metadata::VorbisComment::get_vendor_string() and FLAC::Metadata::VorbisComment::set_vendor_string() to use a UTF-8, NUL-terminated string const FLAC__byte * for the vendor string instead of FLAC::Metadata::VorbisComment::Entry.
        • +
      • Added FLAC::Metadata::*::assign() to all Metadata objects.

+ +
    +
  • + General: +
      +
    • Ogg FLAC seeking now works
      • +
    • New optimizations almost double the decoding speed on PowerPC (e.g. Mac G4/G5)
      • +
    • A native OS X release thanks to updated Project Builder and autotools files
      • +
    +
    • +
  • + FLAC format: +
      +
    • Made invalid the metadata block type 127 so that audio frames can always be distinguished from metadata by seeing 0xff as the first byte. (This was also required for the Ogg FLAC mapping.)
      • +
    +
    • +
  • + Ogg FLAC format: +
      +
    • First official FLAC->Ogg bitstream mapping standardized (see new FLAC-to-Ogg mapping specification). See the documentation for the --ogg switch about having to re-encode older Ogg FLAC files.
      • +
    +
    • +
  • + flac: +
      +
    • Print an error when output file already exists instead of automatically overwriting.
      • +
    • New option -f (--force) to force overwriting if the output file already exists.
      • +
    • New option --cue to select a specific section to decode using cuesheet track/index points.
      • +
    • New option --totally-silent to suppress all output.
      • +
    • New (but undocumented) option --apply-replaygain-which-is-not-lossless which applies ReplayGain to the decoded output. See this thread for usage and caveats.
      • +
    • When encoding to Ogg FLAC, use a random serial number (instead of 0 as was done before) when a serial number is not specified.
      • +
    • When encoding multiple Ogg FLAC streams, --serial-number or random serial number sets the first number, which is then incremented for subsequent streams (before, the same serial number was used for all streams).
      • +
    • Decoder no longer exits with an error when writing to stdout and the pipe is broken.
      • +
    • Better explanation of common error messages.

+ comparison +
+
+
+ Many lossless comparisons look at only compression ratio and speed. FLAC decoding is the fastest among lossless codecs and it has the fastest encoding mode. FLAC's compression is within 3% of even the most complex codecs. Note that the compression ratios of all lossless codecs fall in a quite narrow range; the difference between the very best and very worst is only around 7%, and only 4% for the practical codecs.
+
+ So the evaluation of lossless codecs typically depends mainly on other features, which is what our first table shows; features like how well it is supported in devices and software, licensing, etc. Additionally, as archiving is one of the main applications for a lossless codec, of chief importance is the ability to use and recover data in the future. FLAC stands out as the most widely supported codec, and the only codec that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.
+
+ The rest of the tables show in detail the compression ratios and speed of the codecs in different modes. FLAC's high decoding speed is due to very low complexity and is instrumental to its support by dozens of consumer electronic devices.
+
+ (Note: this comparison leaves out some archaic or impractical codecs; see below for some other comparisons.)

+
+ The machine used for encoding the test files is a PII-333 with 256 megs of RAM, running Windows NT 4.0 SP5. Unfortunately, though flac runs just about everywhere, Windows is the lowest-common-denominator platform for all the encoders. Apple Lossless was tested on a newer machine (P4-2.4GHz Windows 2000); only the overall encoding and decoding times are shown, and the times are scaled to the PII-333 by multiplying by the ratio of flac times on the PII to P4.
+
+ By default when processing files, flac computes the MD5 sum while encoding and decoding. Since MD5 sums are not typically used in playback, and since most codecs either do not support MD5 sums or do not compute them by default, to make the comparison as accurate as possible MD5 checking was disabled for FLAC decoding. However since it is currently not possible to disable MD5 computation for FLAC encoding, the FLAC encoding times here are 4-15% longer than they would be without MD5 checking.
+
+ The audio corpus currently consists entirely of CD music tracks. In the future it may include more kinds of input (like speech, other sample rates/resolutions, etc). There are 14 tracks whose genres range from rock to pop to death metal to classical to chant.
+
+ Here is a summary table of results on the whole corpus, using just the most 'economic' modes (the ones that give the most compression for the least amount of encode/decode time) for each codec. The table is ordered by the average track compression ratio, which is the average of the ratios for each track; this keeps long tracks from having more influence than short ones. Clicking the column header links will take you to complete tables ordered by that column.
+
+ Shown in white, flac in its default mode is right in the middle with respect to compression, relatively fast on the encoding range, and the fastest decoding. This is about what you would expect; FLAC is designed to put most of the processing on the encoding side, which is only done once, whereas the adaptive codecs take as long to decode as encode. FLAC is more suited in this way for playback on low-power devices, borne out by the many hardware devices which support it.

+
+ FLAC is an open source project and we are happy to enlist the help of anyone who wants to contribute, or to help with FLAC support in other programs and devices. The preferred method of communication is the developer mailing list (you must subscribe to post).
+
+ FLAC is open to third-party developers who want to add support for FLAC into their programs. All the necessary functionality is contained the libFLAC libraries which are licensed under Xiph.org's BSD license.
+
+ Some pointers to developer documentation and code:
+ + More resources are available on the FLAC project page on Sourceforge.net. +
+
+
+ +
+ +
+
+ goals +
+
+
+ Since FLAC is an open-source project, it's important to have a set of goals that everyone works to. They may change slightly from time to time but they're a good guideline. Changes should be in line with the goals and should not attempt to embrace any of the anti-goals.
+
+ Goals +
    +
  • + FLAC should be and stay an open format with an open-source reference implementation. +
    • +
  • + FLAC should be lossless. This seems obvious but lossy compression seems to creep into every audio codec. This goal also means that flac should stay archival quality and be truly lossless for all input. Testing of releases should be thorough. +
    • +
  • + FLAC should yield respectable compression, on par or better than other lossless codecs. +
    • +
  • + FLAC should allow at least realtime decoding on even modest hardware. +
    • +
  • + FLAC should support fast sample-accurate seeking. +
    • +
  • + FLAC should allow gapless playback of consecutive streams. This follows from the lossless goal. +
    • +
  • + The FLAC project owes a lot to the many people who have advanced the audio compression field so freely, and aims also to contribute through the open-source development of new ideas. +
    • +
+ Anti-goals
+
    +
  • + Lossy compression. There are already many suitable lossy formats (Ogg Vorbis, MP3, etc.). +
    • +
  • + Copy prevention, DRM, etc. There is no intention to add any copy prevention methods. Of course, we can't stop someone from encrypting a FLAC stream in another container (e.g. the way Apple encrypts AAC in MP4 with FairPlay), that is the choice of the user. +

+
+
+ To report a bug, please go to the FLAC bug tracker (or appropriately the feature request tracker, patch page, or support page).
+
+ First check that there is not already an existing request. If you do submit a new request, make sure and provide an email contact and use the Monitor feature.
+
+ Note that we get many false bug reports from people with faulty hardware or who overclock their machines that FLAC is not working. Please do due diligence if you are getting FLAC encoding or decoding errors that it is not the fault of the hardware. FLAC encoding tends to highlight problems with bad RAM, corrupted files, and excessive overclocking. +

+
+ format +
+
+
+ The basic structure of a FLAC stream is: +
    +
  • The four byte string "fLaC"
    • +
  • The STREAMINFO metadata block
    • +
  • Zero or more other metadata blocks
    • +
  • One or more audio frames
    • +
+ The first four bytes are to identify the FLAC stream. The metadata that follows contains all the information about the stream except for the audio data itself. After the metadata comes the encoded audio data.
+
+ METADATA
+
+ FLAC defines several types of metadata blocks (see the format page for the complete list). Metadata blocks can be any length and new ones can be defined. A decoder is allowed to skip any metadata types it does not understand. Only one is mandatory: the STREAMINFO block. This block has information like the sample rate, number of channels, etc., and data that can help the decoder manage its buffers, like the minimum and maximum data rate and minimum and maximum block size. Also included in the STREAMINFO block is the MD5 signature of the unencoded audio data. This is useful for checking an entire stream for transmission errors.
+
+ Other blocks allow for padding, seek tables, tags, cuesheets, and application-specific data. There are flac options for adding PADDING blocks or specifying seek points. FLAC does not require seek points for seeking but they can speed up seeks, or be used for cueing in editing applications.
+
+ Also, if you have a need of a custom metadata block, you can define your own and request an ID here. Then you can reserve a PADDING block of the correct size when encoding, and overwrite the padding block with your APPLICATION block after encoding. The resulting stream will be FLAC compatible; decoders that are aware of your metadata can use it and the rest will safely ignore it.
+
+ AUDIO DATA
+
+ After the metadata comes the encoded audio data. Audio data and metadata are not interleaved. Like most audio codecs, FLAC splits the unencoded audio data into blocks, and encodes each block separately. The encoded block is packed into a frame and appended to the stream. The reference encoder uses a single block size for the whole stream but the FLAC format does not require it.
+
+ BLOCKING
+
+ The block size is an important parameter to encoding. If it is too small, the frame overhead will lower the compression. If it is too large, the modeling stage of the compressor will not be able to generate an efficient model. Understanding FLAC's modeling will help you to improve compression for some kinds of input by varying the block size. In the most general case, using linear prediction on 44.1kHz audio, the optimal block size will be between 2-6 ksamples. flac defaults to a block size of 4096 in this case. Using the fast fixed predictors, a smaller block size is usually preferable because of the smaller frame header.
+
+ INTER-CHANNEL DECORRELATION
+
+ In the case of stereo input, once the data is blocked it is optionally passed through an inter-channel decorrelation stage. The left and right channels are converted to center and side channels through the following transformation: mid = (left + right) / 2, side = left - right. This is a lossless process, unlike joint stereo. For normal CD audio this can result in significant extra compression. flac has two options for this: -m always compresses both the left-right and mid-side versions of the block and takes the smallest frame, and -M, which adaptively switches between left-right and mid-side.
+
+ MODELING
+
+ In the next stage, the encoder tries to approximate the signal with a function in such a way that when the approximation is subracted, the result (called the residual, residue, or error) requires fewer bits-per-sample to encode. The function's parameters also have to be transmitted so they should not be so complex as to eat up the savings. FLAC has two methods of forming approximations: 1) fitting a simple polynomial to the signal; and 2) general linear predictive coding (LPC). I will not go into the details here, only some generalities that involve the encoding options.
+
+ First, fixed polynomial prediction (specified with -l 0) is much faster, but less accurate than LPC. The higher the maximum LPC order, the slower, but more accurate, the model will be. However, there are diminishing returns with increasing orders. Also, at some point (usually around order 9) the part of the encoder that guesses what is the best order to use will start to get it wrong and the compression will actually decrease slightly; at that point you will have to you will have to use the exhaustive search option -e to overcome this, which is significantly slower.
+
+ Second, the parameters for the fixed predictors can be transmitted in 3 bits whereas the parameters for the LPC model depend on the bits-per-sample and LPC order. This means the frame header length varies depending on the method and order you choose and can affect the optimal block size.
+
+ RESIDUAL CODING
+
+ Once the model is generated, the encoder subracts the approximation from the original signal to get the residual (error) signal. The error signal is then losslessly coded. To do this, FLAC takes advantage of the fact that the error signal generally has a Laplacian (two-sided geometric) distribution, and that there are a set of special Huffman codes called Rice codes that can be used to efficiently encode these kind of signals quickly and without needing a dictionary.
+
+ Rice coding involves finding a single parameter that matches a signal's distribution, then using that parameter to generate the codes. As the distribution changes, the optimal parameter changes, so FLAC supports a method that allows the parameter to change as needed. The residual can be broken into several contexts or partitions, each with it's own Rice parameter. flac allows you to specify how the partitioning is done with the -r option. The residual can be broken into 2^n partitions, by using the option -r n,n. The parameter n is called the partition order. Furthermore, the encoder can be made to search through m to n partition orders, taking the best one, by specifying -r m,n. Generally, the choice of n does not affect encoding speed but m,n does. The larger the difference between m and n, the more time it will take the encoder to search for the best order. The block size will also affect the optimal order.
+
+ FRAMING
+
+ An audio frame is preceded by a frame header and trailed by a frame footer. The header starts with a sync code, and contains the minimum information necessary for a decoder to play the stream, like sample rate, bits per sample, etc. It also contains the block or sample number and an 8-bit CRC of the frame header. The sync code, frame header CRC, and block/sample number allow resynchronization and seeking even in the absence of seek points. The frame footer contains a 16-bit CRC of the entire encoded frame for error detection. If the reference decoder detects a CRC error it will generate a silent block.
+
+ MISCELLANEOUS
+
+ As a convenience, the reference decoder knows how to skip ID3v1 and ID3v2 tags. Note however that the FLAC specification does not require compliant implementations to support ID3 in any form and their use is strongly discouraged.
+
+ flac has a verify option -V that verifies the output while encoding. With this option, a decoder is run in parallel to the encoder and its output is compared against the original input. If a difference is found flac will stop with an error. +

+ flac +
+
+
+ Table of Contents + + General Usage
+
+ flac is the command-line file encoder/decoder. The encoder currently supports as input RIFF WAVE, Wave64, RF64, AIFF, FLAC or Ogg FLAC format, or raw interleaved samples. The decoder currently can output to RIFF WAVE, Wave64, RF64, or AIFF format, or raw interleaved samples. flac only supports linear PCM samples (in other words, no A-LAW, uLAW, etc.), and the input must be between 4 and 24 bits per sample. This is not a limitation of the FLAC format, just the reference encoder/decoder.
+
+ flac assumes that files ending in ".wav" or that have the RIFF WAVE header present are WAVE files, files ending in ".w64" or have the Wave64 header present are Wave64 files, files ending in ".rf64" or have the RF64 header present are RF64 files, files ending in ".aif" or ".aiff" or have the AIFF header present are AIFF files, and files ending in ".flac" or have the FLAC header present are FLAC files. This assumption may be overridden with a command-line option. It also assumes that files ending in ".oga" or ".ogg" or have the Ogg FLAC header present are Ogg FLAC files. Other than this, flac makes no assumptions about file extensions, though the convention is that FLAC files have the extension ".flac" (or ".fla" on ancient "8.3" file systems like FAT-16).
+
+ Before going into the full command-line description, a few other things help to sort it out: 1) flac encodes by default, so you must use -d to decode; 2) the options -0 .. -8 (or --fast and --best) that control the compression level actually are just synonyms for different groups of specific encoding options (described later) and you can get the same effect by using the same options; 3) flac behaves similarly to gzip in the way it handles input and output files.
+
+ Skip to the tutorial below for examples of some common tasks.
+
+ flac will be invoked one of four ways, depending on whether you are encoding, decoding, testing, or analyzing: + + In any case, if no inputfile is specified, stdin is assumed. If only one inputfile is specified, it may be "-" for stdin. When stdin is used as input, flac will write to stdout. Otherwise flac will perform the desired operation on each input file to similarly named output files (meaning for encoding, the extension will be replaced with ".flac", or appended with ".flac" if the input file has no extension, and for decoding, the extension will be ".wav" for WAVE output and ".raw" for raw output). The original file is not deleted unless --delete-input-file is specified.
+
+ If you are encoding/decoding from stdin to a file, you should use the -o option like so: +
    +
  • + flac [options] -o outputfile +
    • +
  • + flac -d [options] -o outputfile +
    • +
+ which are better than: +
    +
  • + flac [options] > outputfile +
    • +
  • + flac -d [options] > outputfile +
    • +
+ since the former allows flac to seek backwards to write the STREAMINFO or RIFF WAVE header contents when necessary.
+
+ Also, you can force output data to go to stdout using -c.
+
+ To encode or decode files that start with a dash, use -- to signal the end of options, to keep the filenames themselves from being treated as options: +
    +
  • + flac -V -- -01-filename.wav +
    • +
+ The encoding options affect the compression ratio and encoding speed. The format options are used to tell flac the arrangement of samples if the input file (or output file when decoding) is a raw file. If it is a RIFF WAVE, Wave64, RF64, or AIFF file the format options are not needed since they are read from the file's header.
+
+ In test mode, flac acts just like in decode mode, except no output file is written. Both decode and test modes detect errors in the stream, but they also detect when the MD5 signature of the decoded audio does not match the stored MD5 signature, even when the bitstream is valid.
+
+ flac can also re-encode FLAC files. In other words, you can specify a FLAC or Ogg FLAC file as an input to the encoder and it will decoder it and re-encode it according to the options you specify. It will also preserve all the metadata unless you override it with other options (e.g. specifying new tags, seekpoints, cuesheet, padding, etc.).
+
+ flac has been tuned so that the default settings yield a good speed vs. compression tradeoff for many kinds of input. However, if you are looking to maximize the compression rate or speed, or want to use the full power of FLAC's metadata system, see About the FLAC Format.
+
+ + Tutorial
+
+ Some common encoding tasks using flac:
+
+ flac abc.wav
+ Encode abc.wav to abc.flac using the default compression setting. abc.wav is not deleted.
+
+ flac --delete-input-file abc.wav
+ Like above, except abc.wav is deleted if there were no errors.
+
+ flac --delete-input-file -w abc.wav
+ Like above, except abc.wav is deleted if there were no errors or warnings.
+
+ flac --best abc.wav
+ Encode abc.wav to abc.flac using the highest compression setting.
+
+ flac --verify abc.wav
+ Encode abc.wav to abc.flac and internally decode abc.flac to make sure it matches abc.wav.
+
+ flac -o my.flac abc.wav
+ Encode abc.wav to my.flac.
+
+ flac -T "TITLE=Bohemian Rhapsody" -T "ARTIST=Queen" abc.wav
+ Encode abc.wav and add some tags at the same time to abc.flac.
+
+ flac *.wav
+ Encode all .wav files in the current directory. NOTE: Wildcards on Windows
+
+ flac abc.aiff
+ Encode abc.aiff to abc.flac.
+
+ flac abc.rf64
+ Encode abc.rf64 to abc.flac.
+
+ flac abc.w64
+ Encode abc.w64 to abc.flac.
+
+ flac abc.flac --force
+ This one's a little tricky: notice that flac is in encode mode by default (you have to specify -d to decode) so this command actually recompresses abc.flac back to abc.flac. --force is needed to make sure you really want to overwrite abc.flac with a new version. Why would you want to do this? It allows you to recompress an existing FLAC file with (usually) higher compression options or a newer version of FLAC and preserve all the metadata like tags too.
+
+ + Some common decoding tasks using flac:
+
+ flac -d abc.flac
+ Decode abc.flac to abc.wav. abc.flac is not deleted. NOTE: Without -d it means re-encode abc.flac to abc.flac (see above).
+
+ flac -d --force-aiff-format abc.flac
+ flac -d -o abc.aiff abc.flac
+ Two different ways of decoding abc.flac to abc.aiff (AIFF format). abc.flac is not deleted.
+
+ flac -d --force-rf64-format abc.flac
+ flac -d -o abc.rf64 abc.flac
+ Two different ways of decoding abc.flac to abc.rf64 (RF64 format). abc.flac is not deleted.
+
+ flac -d --force-wave64-format abc.flac
+ flac -d -o abc.w64 abc.flac
+ Two different ways of decoding abc.flac to abc.w64 (Wave64 format). abc.flac is not deleted.
+
+ flac -d -F abc.flac
+ Decode abc.flac to abc.wav and don't abort if errors are found (useful for recovering as much as possible from corrupted files).
+
+ flac has many other useful options, described below.
+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ General Options +
+ + -v, --version + + Show the flac version number. +
+ + -h, --help + + Show basic usage and a list of all options. Running flac without arguments shows the short help screen by default. +
+ + -H, --explain + + Show detailed explanation of usage and all options. Running flac without arguments shows the short help screen by default. +
+ + -d, --decode + + Decode (flac encodes by default). flac will exit with an exit code of 1 (and print a message, even in silent mode) if there were any errors during decoding, including when the MD5 checksum does not match the decoded output. Otherwise the exit code will be 0. +
+ + -t, --test + + Test (same as -d except no decoded file is written). The exit codes are the same as in decode mode. +
+ + -a, --analyze + + Analyze (same as -d except an analysis file is written). The exit codes are the same as in decode mode. This option is mainly for developers; the output will be a text file that has data about each frame and subframe. +
+ + -c, --stdout + + Write output to stdout. +
+ + -s, --silent + + Silent: do not show encoding/decoding statistics. +
+ + --totally-silent + + Do not print anything of any kind, including warnings or errors. The exit code will be the only way to determine successful completion. +
+ + --no-utf8-convert + + Do not convert tags from local charset to UTF-8. This is useful for scripts, and setting tags in situations where the locale is wrong. This option must appear before any tag options! +
+ + -w, --warnings-as-errors + + Treat all warnings as errors (which cause flac to terminate with a non-zero exit code). +
+ + -f, --force + + Force overwriting of output files. By default, flac warns that the output file already exists and continues to the next file. +
+ + -o filename,
--output-name=filename + 		+ Force the output file name (usually flac just changes the extension). May only be used when encoding a single file. May not be used in conjunction with --output-prefix. +
+ + --output-prefix=string + + Prefix each output file name with the given string. This can be useful for encoding/decoding files to a different directory. Make sure if your string is a path name that it ends with a trailing '/' slash. +
+ + --delete-input-file + + Automatically delete the input file after a successful encode or decode. If there was an error (including a verify error) the input file is left intact. +
+ + --preserve-modtime + + Output files have their timestamps/permissions set to match those of their inputs (this is default). Use --no-preserve-modtime to make output files have the current time and default permissions. +
+ + --keep-foreign-metadata + + If encoding, save WAVE, Wave64, RF64, or AIFF non-audio chunks in FLAC metadata. If decoding, restore any saved non-audio chunks from FLAC metadata when writing the decoded file. Foreign metadata cannot be transcoded, e.g. WAVE chunks saved in a FLAC file cannot be restored when decoding to AIFF. Input and output must be regular files (not stdin or stdout).
+ +
+ + --skip={#|mm:ss.ss} + + Skip over the first # of samples of the input. This works for both encoding and decoding, but not testing. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second.
+
+ Examples:
+
+ --skip=123 : skip the first 123 samples of the input
+ --skip=1:23.45 : skip the first 1 minute and 23.45 seconds of the input +
+ + --until={#|[+|-]mm:ss.ss} + + Stop at the given sample number for each input file. This works for both encoding and decoding, but not testing. The given sample number is not included in the decoded output. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second. If a + sign is at the beginning, the --until point is relative to the --skip point. If a - sign is at the beginning, the --until point is relative to end of the audio.
+
+ Examples:
+
+ --until=123 : decode only the first 123 samples of the input (samples 0-122, stopping at 123)
+ --until=1:23.45 : decode only the first 1 minute and 23.45 seconds of the input
+ --skip=1:00 --until=+1:23.45 : decode 1:00.00 to 2:23.45
+ --until=-1:23.45 : decode everything except the last 1 minute and 23.45 seconds
+ --until=-0:00 : decode until the end of the input (the same as not specifying --until) +
+ + --ogg + + When encoding, generate Ogg FLAC output instead of native FLAC. Ogg FLAC streams are FLAC streams wrapped in an Ogg transport layer. The resulting file should have an '.oga' extension and will still be decodable by flac.
+
+ When decoding, force the input to be treated as Ogg FLAC. This is useful when piping input from stdin or when the filename does not end in '.oga' or '.ogg'.
+
+ NOTE: Ogg FLAC files created prior to flac 1.1.1 used an ad-hoc mapping and do not support seeking. They should be decoded and re-encoded with flac 1.1.1 or later. +
+ + --serial-number=# + + When used with --ogg, specifies the serial number to use for the first Ogg FLAC stream, which is then incremented for each additional stream. When encoding and no serial number is given, flac uses a random number for the first stream, then increments it for each additional stream. When decoding and no number is given, flac uses the serial number of the first page. +
+
+ +
+ +
+ + + + + + + + + + + + +
+ Analysis Options +
+ + --residual-text + + Includes the residual signal in the analysis file. This will make the file very big, much larger than even the decoded file. +
+ + --residual-gnuplot + + Generates a gnuplot file for every subframe; each file will contain the residual distribution of the subframe. This will create a lot of files. +
+
+ +
+ +
+ + + + + + + + + + + + + +
+ Decoding Options +
+ + --cue=[#.#][-[#.#]] + + Set the beginning and ending cuepoints to decode. The optional first #.# is the track and index point at which decoding will start; the default is the beginning of the stream. The optional second #.# is the track and index point at which decoding will end; the default is the end of the stream. If the cuepoint does not exist, the closest one before it (for the start point) or after it (for the end point) will be used. If those don't exist, the start of the stream (for the start point) or end of the stream (for the end point) will be used. The cuepoints are merely translated into sample numbers then used as --skip and --until.
+
+ Examples:
+
+ --cue=- : decode the entire stream
+ --cue=4.1 : decode from track 4, index 1 to the end of the stream
+ --cue=4.1- : decode from track 4, index 1 to the end of the stream
+ --cue=-4.1 : decode from the beginning of the stream up to, but not including, track 4, index 1
+ --cue=2.1-2.4 : decode from track 2, index 1, up to, but not including, track 2, index 4
+ --cue=9.1-10.1 : decode from track 9 the way it would be played on a CD player; this works even if the CD has no 10th track. +
+ + -F,
--decode-through-errors + 		+ By default flac stops decoding with an error and removes the partially decoded file if it encounters a bitstream error. With -F, errors are still printed but flac will continue decoding to completion. Note that errors may cause the decoded audio to be missing some samples or have silent sections. +
+
+ +
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ Encoding Options +
+ + -V, --verify + + Verify the encoding process. With this option, flac will create a parallel decoder that decodes the output of the encoder and compares the result against the original. It will abort immediately with an error if a mismatch occurs. -V increases the total encoding time but is guaranteed to catch any unforseen bug in the encoding process. +
+ + --lax + + Allow encoder to generate non-Subset files. The resulting FLAC file may not be streamable or might have trouble being played in all players (especially hardware devices), so you should only use this option in combination with custom encoding options meant for archival. +
+ + --replay-gain + + Calculate ReplayGain values and store them as FLAC tags, similar to VorbisGain. Title gains/peaks will be computed for each input file, and an album gain/peak will be computed for all files. All input files must have the same resolution, sample rate, and number of channels. Only mono and stereo files are allowed, and the sample rate must be one of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48 kHz. Also note that this option may leave a few extra bytes in a PADDING block as the exact size of the tags is not known until all files are processed.
+
+ Note that this option cannot be used when encoding to standard output (stdout). +
+ + --cuesheet=FILENAME + + Import the given cuesheet file and store it in a CUESHEET metadata block. This option may only be used when encoding a single file. A seekpoint will be added for each index point in the cuesheet to the SEEKTABLE unless --no-cued-seekpoints is specified.
+
+ The cuesheet file must be of the sort written by CDRwin, CDRcue, EAC, etc. See also cuesheet syntax. +
+ + --picture={FILENAME|SPECIFICATION} + + Import a picture and store it in a PICTURE metadata block. More than one --picture command can be specified. Either a filename for the picture file or a more complete specification form can be used. The SPECIFICATION is a string whose parts are separated by | (pipe) characters. Some parts may be left empty to invoke default values. FILENAME is just shorthand for ||||FILENAME. The format of SPECIFICATION is
+
+   [TYPE]|[MIME-TYPE]|[DESCRIPTION]|[WIDTHxHEIGHTxDEPTH[/COLORS]]|FILE
+
+ TYPE is optional; it is a number from one of:
+
    +
  • 0: Other
    • +
  • 1: 32x32 pixels 'file icon' (PNG only)
    • +
  • 2: Other file icon
    • +
  • 3: Cover (front)
    • +
  • 4: Cover (back)
    • +
  • 5: Leaflet page
    • +
  • 6: Media (e.g. label side of CD)
    • +
  • 7: Lead artist/lead performer/soloist
    • +
  • 8: Artist/performer
    • +
  • 9: Conductor
    • +
  • 10: Band/Orchestra
    • +
  • 11: Composer
    • +
  • 12: Lyricist/text writer
    • +
  • 13: Recording Location
    • +
  • 14: During recording
    • +
  • 15: During performance
    • +
  • 16: Movie/video screen capture
    • +
  • 17: A bright coloured fish
    • +
  • 18: Illustration
    • +
  • 19: Band/artist logotype
    • +
  • 20: Publisher/Studio logotype
    • +
+ The default is 3 (front cover). There may only be one picture each of type 1 and 2 in a file.
+
+ MIME-TYPE is optional; if left blank, it will be detected from the file. For best compatibility with players, use pictures with MIME type image/jpeg or image/png. The MIME type can also be --> to mean that FILE is actually a URL to an image, though this use is discouraged.
+
+ DESCRIPTION is optional; the default is an empty string.
+
+ The next part specfies the resolution and color information. If the MIME-TYPE is image/jpeg, image/png, or image/gif, you can usually leave this empty and they can be detected from the file. Otherwise, you must specify the width in pixels, height in pixels, and color depth in bits-per-pixel. If the image has indexed colors you should also specify the number of colors used. When manually specified, it is not checked against the file for accuracy.
+
+ FILE is the path to the picture file to be imported, or the URL if MIME type is -->
+
+ For example, the specification |image/jpeg|||../cover.jpg will embed the JPEG file at ../cover.jpg, defaulting to type 3 (front cover) and an empty description. The resolution and color info will be retrieved from the file itself.
+
+ The specification 4|-->|CD|320x300x24/173|http://blah.blah/backcover.tiff will embed the given URL, with type 4 (back cover), description "CD", and a manually specified resolution of 320x300, 24 bits-per-pixel, and 173 colors. The file at the URL will not be fetched; the URL itself is stored in the PICTURE metadata block. +
+ + --sector-align + + Align encoding of multiple CD format files on sector boundaries. This option is only allowed when encoding files all of which have a 44.1kHz sample rate and 2 channels. With --sector-align, the encoder will align the resulting .flac streams so that their lengths are even multiples of a CD sector (1/75th of a second, or 588 samples). It does this by carrying over any partial sector at the end of each file to the next stream. The last stream will be padded to alignment with zeroes.
+
+ This option will have no effect if the files are already aligned (as is the normally the case with WAVE files ripped from a CD). flac can only align a set of files given in one invocation of flac.
+
+ WARNING: The ordering of files is important! If you give a command like 'flac --sector-align *.wav' the shell may not expand the wildcard to the order you expect. To be safe you should 'echo *.wav' first to confirm the order, or be explicit like 'flac --sector-align 8.wav 9.wav 10.wav'.
+
+ NOTE:This option is DEPRECATED and may not exist in future version of flac. shntool provides similar functionality. +
+ + -S {#|X|#x|#s},
--seekpoint={#|X|#x|#s} + 		+ Include a point or points in a SEEKTABLE:
+
    +
  • + #  : a specific sample number for a seek point +
    • +
  • + X  : a placeholder point (always goes at the end of the SEEKTABLE) +
    • +
  • + #x : # evenly spaced seekpoints, the first being at sample 0 +
    • +
  • + #s : a seekpoint every # seconds; # does not have to be a whole number, it can be, for example, 9.5, meaning a seekpoint every 9.5 seconds +
    • +
+ You may use many -S options; the resulting SEEKTABLE will be the unique-ified union of all such values.
+ With no -S options, flac defaults to '-S 10s'. Use --no-seektable for no SEEKTABLE.
+ NOTE: -S #x and -S #s will not work if the encoder can't determine the input size before starting.
+ NOTE: if you use -S # and # is >= samples in the input, there will be either no seek point entered (if the input size is determinable before encoding starts) or a placeholder point (if input size is not determinable).
+
+ + -P #, --padding=# + + Tell the encoder to write a PADDING metadata block of the given length (in bytes) after the STREAMINFO block. This is useful if you plan to tag the file later with an APPLICATION block; instead of having to rewrite the entire file later just to insert your block, you can write directly over the PADDING block. Note that the total length of the PADDING block will be 4 bytes longer than the length given because of the 4 metadata block header bytes. You can force no PADDING block at all to be written with --no-padding. The encoder writes a PADDING block of 8192 bytes by default (or 65536 bytes if the input audio stream is more than 20 minutes long). +
+ + -T FIELD=VALUE,
--tag=FIELD=VALUE + 		+ Add a FLAC tag. The comment must adhere to the Vorbis comment spec (which FLAC tags implement), i.e. the FIELD must contain only legal characters, terminated by an 'equals' sign. Make sure to quote the comment if necessary. This option may appear more than once to add several comments. NOTE: all tags will be added to all encoded files. +
+ + --tag-from-file=FIELD=FILENAME + + Like --tag, except FILENAME is a file whose contents will be read verbatim to set the tag value. The contents will be converted to UTF-8 from the local charset. This can be used to store a cuesheet in a tag (e.g. --tag-from-file="CUESHEET=image.cue"). Do not try to store binary data in tag fields! Use APPLICATION blocks for that. +
+ + -b #, --blocksize=# + + Specify the block size in samples. Subset streams must use one of 192/576/1152/2304/4608/256/512/1024/2048/4096 (and 8192/16384 if the sample rate is >48kHz). The reference encoder uses the same block size for the entire stream. +
+ + -m, --mid-side + + Enable mid-side coding (only for stereo streams). Tends to increase compression by a few percent on average. For each block both the stereo pair and mid-side versions of the block will be encoded, and smallest resulting frame will be stored. +
+ + -M, --adaptive-mid-side + + Enable adaptive mid-side coding (only for stereo streams). Like -m but the encoder adaptively switches between independent and mid-side coding, which is faster but yields less compression than -m (which does an exhaustive search). +
+ + -0 .. -8 + + Fastest compression .. highest compression. The default is -5. +
+ + -0, --compression-level-0 + + Synonymous with -l 0 -b 1152 -r 3 +
+ + -1, --compression-level-1 + + Synonymous with -l 0 -b 1152 -M -r 3 +

+ + --fast + + Fastest compression. Currently synonymous with -0 +
+ + --best + + Highest compression. Currently synonymous with -8 +
+ + -e,
--exhaustive-model-search + 		+ Exhaustive model search (expensive!). Normally the encoder estimates the best model to use and encodes once based on the estimate. With an exhaustive model search, the encoder will generate subframes for every order and use the smallest. If the max LPC order is high this can significantly increase the encode time but can shave off another 0.5%. +
+ + -A "function", --apodization="function" + + Window audio data with given the apodization function. The functions are: bartlett, bartlett_hann, blackman, blackman_harris_4term_92db, connes, flattop, gauss(STDDEV), hamming, hann, kaiser_bessel, nuttall, rectangle, triangle, tukey(P), welch.
+ For gauss(STDDEV), STDDEV is the standard deviation (0<STDDEV<=0.5).
+ For tukey(P), P specifies the fraction of the window that is tapered (0<=P<=1; P=0 corresponds to "rectangle" and P=1 corresponds to "hann").
+ More than one -A option (up to 32) may be used. Any function that is specified erroneously is silently dropped. The encoder chooses suitable defaults in the absence of any -A options; any -A option specified replaces the default(s).
+ When more than one function is specified, then for every subframe the encoder will try each of them separately and choose the window that results in the smallest compressed subframe. Multiple functions can greatly increase the encoding time.
+
+ + -l #, --max-lpc-order=# + + Specifies the maximum LPC order. This number must be <= 32. For Subset streams, it must be <=12 if the sample rate is <=48kHz. If 0, the encoder will not attempt generic linear prediction, and use only fixed predictors. Using fixed predictors is faster but usually results in files being 5-10% larger. +
+ + -q #,
--qlp-coeff-precision=# + 		+ Specifies the precision of the quantized LP coefficients, in bits. The default is -q 0, which means let the encoder decide based on the signal. Unless you really know your input file it's best to leave this up to the encoder. +
+ + -p,
--qlp-coeff-precision-search + 		+ Do exhaustive LP coefficient quantization optimization. This option overrides any -q option. It is expensive and typically will only improve the compression a tiny fraction of a percent. -q has no effect when -l 0 is used. +
+ + -r [#,]#,
--rice-partition-order=[#,]# + 		+ Set the [min,]max residual partition order. The min value defaults to 0 if unspecified.
+
+ By default the encoder uses a single Rice parameter for the subframe's entire residual. With this option, the residual is iteratively partitioned into 2^min# .. 2^max# pieces, each with its own Rice parameter. Higher values of max# yield diminishing returns. The most bang for the buck is usually with -r 2,2 (more for higher block sizes). This usually shaves off about 1.5%. The technique tends to peak out about when blocksize/(2^n)=128. Use -r 0,16 to force the highest degree of optimization. +
+
+ +
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ Format Options +
+ + --endian={big|little} + + Specify big-endian or little-endian byte order in the raw file. +
+ + --channels=# + + Specify the number of channels in the raw file. +
+ + --bps=# + + Specify the number of bits per sample in the raw file. +
+ + --sample-rate=# + + Specify the sample rate of the raw file. +
+ + --sign={signed|unsigned} + + Specify that the samples in the raw file are signed or unsigned (the default is signed). +
+ + --input-size=# + + Specify the size of the raw input in bytes. If you are encoding raw samples from stdin, you must set this option in order to be able to use --skip, --until, --cue-sheet, or other options that need to know the size of the input beforehand. If the size given is greater than what is found in the input stream, the encoder will complain about an unexpected end-of-file. If the size given is less, samples will be truncated. +
+ + --force-raw-format + + Treat the input file (or output file if decoding) as a raw file, regardless of the extension. +
+ + --force-aiff-format + + Force the decoder to output AIFF format. This option is not needed if the output filename (as set by -o) ends with .aif or .aiff. Also, this option has no effect when encoding since input AIFF is auto-detected. +
+ + --force-rf64-format + + Force the decoder to output RF64 format. This option is not needed if the output filename (as set by -o) ends with .rf64. Also, this option has no effect when encoding since input RF64 is auto-detected. +
+ + --force-wave64-format + + Force the decoder to output Wave64 format. This option is not needed if the output filename (as set by -o) ends with .w64. Also, this option has no effect when encoding since input Wave64 is auto-detected. +

+ metaflac +
+
+
+ Table of Contents + + General Usage
+
+ metaflac is the command-line .flac file metadata editor. You can use it to list the contents of metadata blocks, edit, delete or insert blocks, and manage padding.
+
+ metaflac takes a set of "options" (though some are not optional) and a set of FLAC files to operate on. There are three kinds of "options": +
    +
  • + Major operations, which specify a mode of operation like listing blocks, removing blocks, etc. These will have sub-operations describing exactly what is to be done. +
    • +
  • + Shorthand operations, which are convenient synonyms for major operations. For example, there is a shorthand operation --show-sample-rate that shows just the sample rate field from the STREAMINFO metadata block. +
    • +
  • + Global options, which affect all the operations. +
    • +
+ All of these are described in the tables below. At least one shorthand or major operation must be supplied. You can use multiple shorthand operations to do more than one thing to a file or set of files. Most of the common things to do to metadata have shorthand operations. As an example, here is how to show the MD5 signatures for a set of three FLAC files:
+
+ metaflac --show-md5sum file1.flac file2.flac file3.flac
+
+ Another example; this removes all DESCRIPTION and COMMENT tags in a set of FLAC files, and uses the --preserve-modtime global option to keep the FLAC file modification times the same (usually when files are edited the modification time is set to the current time):
+
+ metaflac --preserve-modtime --remove-tag=DESCRIPTION --remove-tag=COMMENT file1.flac file2.flac file3.flac
+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + +
+ Global Options +
+ + --preserve-modtime + + Preserve the original modification time in spite of edits. +
+ + --with-filename + + Prefix each output line with the FLAC file name (the default if more than one FLAC file is specified). +
+ + --no-filename + + Do not prefix each output line with the FLAC file name (the default if only one FLAC file is specified) +
+ + --no-utf8-convert + + Do not convert tags from UTF-8 to local charset, or vice versa. This is useful for scripts, and setting tags in situations where the locale is wrong. +
+ + --dont-use-padding + + By default metaflac tries to use padding where possible to avoid rewriting the entire file if the metadata size changes. Use this option to tell metaflac to not take advantage of padding this way. +
+
+ +
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ Shorthand Operations +
+ + --show-md5sum + + Show the MD5 signature from the STREAMINFO block. +
+ + --show-min-blocksize + + Show the minimum block size from the STREAMINFO block. +
+ + --show-max-blocksize + + Show the maximum block size from the STREAMINFO block. +
+ + --show-min-framesize + + Show the minimum frame size from the STREAMINFO block. +
+ + --show-max-framesize + + Show the maximum frame size from the STREAMINFO block. +
+ + --show-sample-rate + + Show the sample rate from the STREAMINFO block. +
+ + --show-channels + + Show the number of channels from the STREAMINFO block. +
+ + --show-bps + + Show the # of bits per sample from the STREAMINFO block. +
+ + --show-total-samples + + Show the total # of samples from the STREAMINFO block. +
+ + --show-vendor-tag + + Show the vendor string from the VORBIS_COMMENT block. +
+ + --show-tag=NAME + + Show all tags where the the field name matches NAME. +
+ + --remove-tag=NAME + + Remove all tags whose field name is NAME. +
+ + --remove-first-tag=NAME + + Remove first tag whose field name is NAME. +
+ + --remove-all-tags + + Remove all tags, leaving only the vendor string. +
+ + --set-tag=FIELD + + Add a tag. The FIELD must comply with the Vorbis comment spec, of the form NAME=VALUE. If there is currently no tag block, one will be created. +
+ + --set-tag-from-file=FIELD + + Like --set-tag, except the VALUE is a filename whose contents will be read verbatim to set the tag value. Unless --no-utf8-convert is specified, the contents will be converted to UTF-8 from the local charset. This can be used to store a cuesheet in a tag (e.g. --set-tag-from-file="CUESHEET=image.cue"). Do not try to store binary data in tag fields! Use APPLICATION blocks for that. +
+ + --import-tags-from=FILE + + Import tags from a file. Use - for stdin. Each line should be of the form NAME=VALUE. Multi-line comments are currently not supported. Specify --remove-all-tags and/or --no-utf8-convert before --import-tags-from if necessary. If FILE is - (stdin), only one FLAC file may be specified. +
+ + --export-tags-to=FILE + + Export tags to a file. Use - for stdin. Each line will be of the form NAME=VALUE. Specify --no-utf8-convert if necessary. +
+ + --import-cuesheet-from=FILE + + Import a cuesheet from a file. Use - for stdin. Only one FLAC file may be specified. A seekpoint will be added for each index point in the cuesheet to the SEEKTABLE unless --no-cued-seekpoints is specified. +
+ + --export-cuesheet-to=FILE + + Export CUESHEET block to a cuesheet file, suitable for use by CD authoring software. Use - for stdout. Only one FLAC file may be specified on the command line. +
+ + --import-picture-from={FILENAME|SPECIFICATION} + + Import a picture and store it in a PICTURE metadata block. See the flac option --picture for an explanation of the SPECIFICATION syntax. +
+ + --export-picture-to=FILE + + Export PICTURE block to a file. Use - for stdout. Only one FLAC file may be specified on the command line. The first PICTURE block will be exported unless --export-picture-to is preceded by a --block-number=# option to specify the exact metadata block to extract. Note that the block number is the one shown by --list. +
+ + --add-replay-gain + + Calculates the title and album gains/peaks of the given FLAC files as if all the files were part of one album, then stores them as FLAC tags. The tags are the same as those used by vorbisgain. Existing ReplayGain tags will be replaced. If only one FLAC file is given, the album and title gains will be the same. Since this operation requires two passes, it is always executed last, after all other operations have been completed and written to disk. All FLAC files specified must have the same resolution, sample rate, and number of channels. The sample rate must be one of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48 kHz. +
+ + --remove-replay-gain + + Removes the ReplayGain tags. +
+ + --add-seekpoint={#|X|#x|#s} + + Add seek points to a SEEKTABLE block:
+
    +
  • + #  : a specific sample number for a seek point +
    • +
  • + X  : a placeholder point (always goes at the end of the SEEKTABLE) +
    • +
  • + #x : # evenly spaced seekpoints, the first being at sample 0 +
    • +
  • + #s : a seekpoint every # seconds; # does not have to be a whole number, it can be, for example, 9.5, meaning a seekpoint every 9.5 seconds +
    • +
+ If no SEEKTABLE block exists, one will be created. If one already exists, points will be added to the existing table, and any duplicates will be turned into placeholder points.
+ You may use many --add-seekpoint options; the resulting SEEKTABLE will be the unique-ified union of all such values. Example: --add-seekpoint=100x --add-seekpoint=3.5s will add 100 evenly spaced seekpoints and a seekpoint every 3.5 seconds.
+
+ + --add-padding=# + + Add a padding block of the given length (in bytes). The overall length of the new block will be 4 + length; the extra 4 bytes is for the metadata block header. +
+
+ +
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ Major Operations +
+ + --version + + Show the metaflac version number. +
+ + --list + + List the contents of one or more metadata blocks to stdout. By default, all metadata blocks are listed in text format. Use the following options to change this behavior:
+
+ + --block-number=#[,#[...]]
+ An optional comma-separated list of block numbers to display. The first block, the STREAMINFO block, is block 0.
+
+ + --block-type=type[,type[...]]
+ --except-block-type=type[,type[...]]
+ An optional comma-separated list of block types to be included or ignored with this option. Use only one of --block-type or --except-block-type. The valid block types are: STREAMINFO, PADDING, APPLICATION, SEEKTABLE, VORBIS_COMMENT. You may narrow down the types of APPLICATION blocks displayed as follows:
+ + + + + + + + + +
APPLICATION:abcdThe APPLICATION block(s) whose textual representation of the 4-byte ID is "abcd"
APPLICATION:0xXXXXXXXXThe APPLICATION block(s) whose hexadecimal big- endian representation of the 4-byte ID is "0xXXXXXXXX". For the example "abcd" above the hexadecimal equivalalent is 0x61626364
+
+ + NOTE: if both --block-number and --[except-]block-type are specified, the result is the logical AND of both arguments.
+
+ + --application-data-format=hexdump|text
+ If the application block you are displaying contains binary data but your --data-format=text, you can display a hex dump of the application data contents instead using --application-data-format=hexdump. +
+ + --remove + + Remove one or more metadata blocks from the metadata. Unless --dont-use-padding is specified, the blocks will be replaced with padding. You may not remove the STREAMINFO block.
+
+ + --block-number=#[,#[...]]
+ --block-type=type[,type[...]]
+ --except-block-type=type[,type[...]]
+ See --list above for usage.
+
+ + NOTE: if both --block-number and --[except-]block-type are specified, the result is the logical AND of both arguments. +
+ + --remove-all + + Remove all metadata blocks (except the STREAMINFO block) from the metadata. Unless --dont-use-padding is specified, the blocks will be replaced with padding. +
+ + --merge-padding + + Merge adjacent PADDING blocks into single blocks. +
+ + --sort-padding + + Move all PADDING blocks to the end of the metadata and merge them into a single block. +

+ xmms plugin +
+
+
+ Normally the FLAC plugin for XMMS is installed with a package, but some of the binary builds have a compiled plugin. All that is necessary is to copy libxmms-flac.so to the directory where XMMS looks for input plugins (usually /usr/lib/xmms/Input or $HOME/.xmms/Input). There is nothing else to configure. Make sure to restart XMMS before trying to play any .flac files. +
+
+
+ +
+ +
+
+ winamp plugin +
+
+
+ Since Winamp 5.31, Nullsoft has supplied a FLAC plugin with their Full install; nothing else is needed to get FLAC to play in Wnamp.
+
+ Before Winamp 5.31 it was necessary to use our FLAC plugin. If you have an older version of Winamp, our plugin is still available in the FLAC Installer for Windows. The Winamp plugin should work for both Winamp2 and Winamp5. All that is necessary is to copy in_flac.dll to the Plugins/ directory of your Winamp installation. There is nothing else to configure. Make sure to restart Winamp before trying to play any .flac files. +

+ General +

+ + What is FLAC?
+
+ FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.
+
+ For more details, see What is FLAC?
+
+ I have a FLAC file, how do I play it?
+ How can I create FLAC files?
+
+ See Using FLAC.
+
+ What licensing applies to the FLAC format and software?
+
+ See the license page.
+
+ What kinds of tags does FLAC support?
+
+ FLAC has it's own native tagging system which is identical to that of Vorbis. They are called alternately "FLAC tags" and "Vorbis comments". It is the only tagging system required and guaranteed to be supported by FLAC implementations.
+
+ Out of convenience, the reference decoder knows how to skip ID3 tags so that they don't interfere with decoding. But you should not expect any tags beside FLAC tags to be supported in applications; some implementations may not even be able to decode a FLAC file with ID3 tags.
+
+ What software support FLAC?
+
+ This list is so large now it is difficult to maintain and keep up-to-date. For a partial list of open-source software that supports FLAC, see the software section of the links page. For a partial list of the most popular software used to encode, decode, play, tag, and rip FLAC files, see the download page.
+
+ How can I play FLAC in Windows Media Player?
+
+ See this guide.
+
+ What hardware products support FLAC?
+
+ See the hardware section of the links page.
+
+ What is the difference between (native) FLAC and Ogg FLAC?
+
+ You can think of an audio codec as having two layers. The inside layer is the raw compressed data, and the outside layer is the "container" or "transport layer" that splits and arranges the compressed data in pieces so it can be seeked through, edited, etc.
+
+ "Native" FLAC is the compressed FLAC data stored in a very minimalist container, designed to be very efficient at storing single audio streams.
+
+ Ogg FLAC is the compressed FLAC data stored in an Ogg container. Ogg is a much more powerful transport layer that enables mixing several kinds of different streams (audio, data, metadata, etc). The overhead is slightly higher than with native FLAC.
+
+ In either case, the compressed FLAC data is the same and one can be converted to the other without re-encoding.
+
+ Which should I use, (native) FLAC or Ogg FLAC?
+
+ The short answer right now is probably "native FLAC". If all you are doing is compressing audio to be played back later, native FLAC will do everything you need, is more widely supported, and will yield smaller files. If you plan to edit the compressed audio, or want to multiplex the audio with video later in an Ogg container, Ogg FLAC is a better choice.
+
+ Why aren't PERFORMER/TITLE/etc tags stored in the FLAC CUESHEET block?
+
+ This has turned out to be a pretty polarizing issue and requires a long explanation.
+
+ The original purpose of a cue sheet in CD authoring software was to lay out the disc, essentially specifying how the audio will be organized on the disc; some of the information ends up as the CD table of contents: the track numbers and locations, and the index points. Later CD-TEXT was added. But CD-TEXT is a very complex spec, and actually goes in the CD subcode data. It is internationalized, not through Unicode, but with several different character sets, some of them multi-byte. It even allows for graphics. In cue sheets, the TITLE/PERFORMER/etc tags are just a limited shorthand for authoring CD-TEXT, but when you rip, you almost never parse the CD-TEXT, you get it from another database, and it doesn't really belong in the FLAC CUESHEET block.
+
+ For FLAC the intention is that applications can calculate the CDDB or CDindex ID from the CUESHEET block and look it up in an online or local database just like CD rippers and players do. But if you really want it in the file itself, the track metadata should be stored separate from the CUESHEET, and already can be because of FLAC's metadata system. There just isn't a method specified yet because as soon as it is, people will say that it's not flexible enough. From experience (and you can see this come up time and time again in many lists), anyone who is going to the trouble of keeping a lossless collection in the first place will already be picky about metadata, and it is hard to come up with a standard that will please even the majority. That is the big problem with metadata and is why Xiph has deferred on it, waiting for someone to come up with a good metadata spec that can be multiplexed together with data.
+
+ Some players (for example Foobar2000) allow you to store the CDDB data as FLAC tags and can parse that.
+
+ Why doesn't FLAC store all WAVE metadata?
+ If flac compresses WAVE files, why isn't it technically a WAVE file compressor?
+
+ (By default, flac does not store WAVE metadata, but it can with the --keep-foreign-metadata option described below.)
+
+ FLAC is a general-purpose audio format, not just a compressed WAVE file format. There's a subtle difference. WAVE is a complicated standard; many kinds of data besides audio data can be put in it. FLAC's purpose is not to reproduce a WAVE file, including all the non-audio data that is in it, it is to losslessly compress the audio.
+
+ However, if you really need to store the non-audio parts of a WAVE or AIFF file, you can use the --keep-foreign-metadata option to flac when encoding to store it in FLAC metadata, then use the option again when decoding to restore in to the decoded WAVE/AIFF file.
+
+ Why do some lossless comparisons say FLAC does not support RIFF chunks?
+
+ This is a limitation that no longer exists with FLAC (see above).
+
+ Why do the encoder settings have a big effect on the encoding time but not the decoding time?
+
+ It's hard to explain without going into the codec design, but to oversimplify, the encoder is looking for functions that approximate the signal. Higher settings make the encoder search more to find better approximations. The functions are themselves encoded in the FLAC file. Decoding only requires computing the one chosen function, and the complexity of the function is very stable. This is by design, to make decoding easier, and is one of the things that makes FLAC easy to implement in hardware.
+
+ Why use FLAC instead of other codecs that compress more?
+
+ For most users, a small difference in filesize is usually far outweighed by FLAC's advantages: open patent free codec, portable open source (BSD) reference implementation, documented API, multi-platform support, hardware support, multi-channel support, etc. Improving FLAC to get a little more compression is not worth making it more complex and more compute-intensive to decode, and hence, less likely to be supported in hardware.
+
+ Why can't you make FLAC encode faster?
+
+ FLAC already encodes pretty fast. It is faster than real-time even on weak systems and is not much slower than even the fastest codecs. And it is faster than the CD ripping process with which it is usually paired, meaning even if it went faster, it would not speed up the ripping-encoding process anyway.
+
+ Part of the reason is that FLAC is asymmetric (see also). That means that it is optimized for decoding speed at the expense of encoding speed, because it makes it easier to decode on low-powered hardware, and because you only encode once but you decode many times.
+
+ How can I be sure FLAC is lossless?
+ How much testing has been done on FLAC?
+
+ First, FLAC is probably the only lossless compressor that has a published and comprehensive test suite. With the others you rely on the author's personal testing or the longevity of the program. But with FLAC you can download the whole test suite and run it on any version you like, or alter it to test your own data. The test suite checks every function in the API, as well as running many thousands of streams through an encode-decode-verify process, to test every nook and cranny of the system. Even on a fast machine the full test suite takes hours. The full test suite must pass on several platforms before a release is made.
+
+ Second, you can always use the -V option with flac (also supported by most GUI frontends) to verify while encoding. With this option, a decoder is run in parallel to the encoder and its output is compared against the original input. If a difference is found flac will stop with an error.
+
+ Finally, FLAC is used by many people and has been judged stable enough by many software and hardware makers to be incorporated into their products.
+
+ What is the lowest bitrate (or highest compression) achievable with FLAC?
+
+ With FLAC you do not specify a bitrate like with some lossy codecs. It's more like specifying a quality with Vorbis or MPC, except with FLAC the quality is always "lossless" and the resulting bitrate is roughly proportional to the amount of information in the original signal. You cannot control the bitrate much and the result can be from around 100% of the input rate (if you are encoding noise), down to almost 0 (encoding silence).
+
+ How many channels does FLAC support?
+
+ FLAC supports from 1 to 8 channels per stream. Channels are only grouped in FLAC to take advantage of interchannel correlation and to define common channel assignments (like stereo L/R, 5.1 surround, et cetera). When encoding a large number of independent channels it is expected that they are coded separately and if required, multiplexed together in a suitable container like Ogg or Matroska.
+
+ What kind of audio samples does FLAC support?
+
+ FLAC supports linear PCM samples with a resolution between 4 and 32 bits per sample. FLAC does not support floating point samples. In some cases it is possible to losslessly transform samples from an incompatible range to a FLAC-compatible range before encoding.
+
+ FLAC supports linear sample rates from 1Hz - 655350Hz in 1Hz increments. + +

+ Tools +

+ + How do I set up EAC to rip directly to FLAC?
+
+ See Case's excellent EAC configuration page. Or use AutoFLAC, Omni Encoder, or MAREO to rip to FLAC or multiple formats at once.
+
+ Why am I getting "Run-time error '75': Path/File access error" with FLAC Frontend?
+
+ Depending on how FLAC Frontend is installed, it could be one of two things: 1) you are trying to encode to file to a directory where you do not have write permission; 2) the FLAC Frontend program must be set to run as Administrator by opening Windows Explorer, navigating to C:\Program Files\FLAC (or wherever FLAC was installed), then right-clicking on FLAC Frontend.exe and checking "Run this program as an administrator".
+
+ How do I encode a file that starts with a dash?
+
+ When using flac to encode on the command-line, a file that starts with a dash will be treated as an option, but there is a simple workaround. Use -- to signal the end of options and the beginning of filenames, like so:
+
+ flac -V -- -01-name.wav
+
+ Why does it take so long to edit some FLAC files with metaflac?
+
+ Since metadata is stored at the beginning of a FLAC file, changing the length of it can sometimes cause the whole file to be rewritten. You can avoid this by adding padding with flac when you encode, or with metaflac after encoding. By default, flac adds 8k of padding; you can change this amount if you need more or less.
+
+ Why don't Unicode file names work with flac/metaflac on Windows?
+
+ Windows implements Unicode filenames differently than all other operating systems, and can only be supported via Windows APIs (non-portable). Also the method is different for different versions of Windows. It's so hard to get right that most programs that have to work for other operating systems also do not support it. A workaround can be found here.
+
+ Why don't wildcards for file names like *.flac or *.wav work with flac/metaflac on Windows?
+
+ The Windows command shells (cmd.exe, command.com) implement wildcard handling differently than most other shells, leaving it up to the program to do everything including difficult and ambiguous cases. For an explanation of why wildcards on cmd.exe/command.com are dangerous, see here. Better command shells for Windows exist, e.g. from Cygwin. A workaround with the Windows shells is to do something like:
+
+ for %F in (*.wav) do flac "%F"
+
+ but care must still be taken that the command will execute as intended.
+
+ I compressed a file to FLAC with verify on, and flac said "Verify FAILED!" Why?
+
+ The only known cause of verify errors is faulty hardware. The dead giveaway is that if you repeat the exact same command, the error occurs in a different place or not at all. This can also happen when decoding or testing a FLAC file. If this is happening it is your hardware and not a FLAC bug.
+
+ The problem is usually caused by overclocking/overheating the CPU or bad RAM. Try one of the many free programs available for testing hardware (e.g. Memtest86+). We have had reports of a few cases where a system is passing with flying colors and still getting unrepeatable FLAC errors, and the one thing many (all?) of these systems have in common is an ASUS motherboard (A7V133 or P3V4X) which we suspect is buggy in some way. (See also)
+
+ If you ever have a verify error that fails at the same place every time, please file a bug, uploading a sample according to the instructions found at the bottom of this bug report.
+
+ I compressed a WAVE file to FLAC, then decompressed to WAVE, and the two weren't identical. Why?
+ I compressed a WAVE file to FLAC and it said "warning: skipping unknown sub-chunk LIST". Why?
+
+ WAVE is a complicated standard; many kinds of data besides audio data can be put in it. Most likely what has happened is that the application that created the original WAVE file also added some extra information for it's own use, which FLAC does not store or recreate by default (but can with the --keep-foreign-metadata option) (see also). The audio data in the two WAVE files will be identical. There are other tools to compare just the audio content of two WAVE files; ExactAudioCopy has such a feature.
+
+ For the more technically inclined, by default FLAC only stores what is in the 'fmt ' and 'data' sub-chunks of a WAVE file. (see also)
+
+ I decoded a FLAC file and the WAVE is 2 bytes shorter than the original. Why?
+
+ The difference is probably that between an 18-byte 'fmt ' subchunk in the original WAVE vs. a 16-byte one in the decoded WAVE. With WAVE there is more than one way to write identical formatting information, but FLAC always writes the most common legal form. (see also)
+
+ Why did I get "ERROR initializing encoder, state = FLAC__STREAM_ENCODER_NOT_STREAMABLE"?
+
+ You specified encoding options that are outside the Streamable subset. If that is what you really wanted and you understand the consequences, you can use flac --lax to generate a non-Subset stream. The resulting file may not be streamable or play in all players.
+
+ Why doesn't the same file compressed on different machines with the same options yield the same FLAC file?
+
+ It's not supposed to, and neither does it mean either encoding was bad. There are many variations between different machines or even different builds of flac on the same machine that can lead to small differences in the FLAC file, even if they have the exact same final size. This is normal. + +

+ API +

+ + Why does your API change for point releases?
+
+ The FLAC release numbering scheme of MAJOR.MINOR.MICRO reflects the state of the FLAC format, not the API. This is most intuitive for users, at the expense of flustering developers. The shared library number (derived from the libtool current:revision:age number) is the indicator of binary API compatibility. As of FLAC 1.1.3, the current, revision, and age numbers are also #defined in the library headers to make porting easier; see the porting guide.
+
+ How can I determine the encoded frame length?
+
+ With native FLAC, it is not possible to determine the frame length without decoding. Probably if I had it all to do again I would have constrained the possible block sizes, which would have made it more practical to put the frame length in the frame header. For an example of how to find the frame boundaries in a stream, see the source code to metaflac, in the functionality that adds seek points.
+
+ With Ogg FLAC, it can be calculated from the Ogg page header. + +

+ Project +

+ + Where are the mailing lists, forums, discussion areas, etc.?
+
+ There are a few places. The main discussions happen on the official FLAC mailing lists (you must subscribe to post). Also, there is a lot of discussion relating to FLAC on Hydrogen Audio.
+
+ How do I submit a bug report?
+
+ First, visit the bug tracking page and do a little searching of both open and closed bugs to see if yours is already there. If you have something truly new, submit a new bug. Make sure to monitor the bug or include your email address in the description. Include as much information as possible: the version of FLAC that you are running, the name and version of any frontend you are running, your operating system and version, your CPU type and speed, the amount of memory you have, where you downloaded FLAC from, the exact error message (if any) copied from the console, and anything else you may think will help. +

+ introduction +
+
+
+ FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.
+
+ FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.
+
+ FLAC supports tagging, cover art, and fast seeking. FLAC is freely available and supported on most operating systems, including Windows, "unix" (Linux, *BSD, Solaris, OS X, IRIX), BeOS, OS/2, and Amiga.
+
+ There are many programs and devices that support FLAC, but the core FLAC project here maintains the format and provides programs and libraries for working with FLAC files. See Getting FLAC for instructions on downloading and installing the official FLAC tools, or Using FLAC for instructions and guides on playing FLAC files, ripping CDs to FLAC, etc.
+
+ When we say that FLAC is "Free" it means more than just that it is available at no cost. It means that the specification of the format is fully open to the public to be used for any purpose (the FLAC project reserves the right to set the FLAC specification and certify compliance), and that neither the FLAC format nor any of the implemented encoding/decoding methods are covered by any known patent. It also means that all the source code is available under open-source licenses. It is the first truly open and free lossless audio format. (For more information, see the license page.)
+
+ Notable features of FLAC: +
    +
  • + Lossless: The encoding of audio (PCM) data incurs no loss of information, and the decoded audio is bit-for-bit identical to what went into the encoder. Each frame contains a 16-bit CRC of the frame data for detecting transmission errors. The integrity of the audio data is further insured by storing an MD5 signature of the original unencoded audio data in the file header, which can be compared against later during decoding or testing. +
    • +
  • + Fast: FLAC is asymmetric in favor of decode speed. Decoding requires only integer arithmetic, and is much less compute-intensive than for most perceptual codecs. Real-time decode performance is easily achievable on even modest hardware. +
    • +
  • + Hardware support: FLAC is supported by dozens of consumer electronic devices, from portable players, to home stereo equipment, to car stereo. +
    • +
  • + Flexible metadata: FLAC's metadata system supports tags, cover art, seek tables, and cue sheets. Applications can write their own APPLICATION metadata once they register an ID. New metadata blocks can be defined and implemented in future versions of FLAC without breaking older streams or decoders. +
    • +
  • + Seekable: FLAC supports fast sample-accurate seeking. Not only is this useful for playback, it makes FLAC files suitable for use in editing applications. +
    • +
  • + Streamable: Each FLAC frame contains enough data to decode that frame. FLAC does not even rely on previous or following frames. FLAC uses sync codes and CRCs (similar to MPEG and other formats), which, along with framing, allow decoders to pick up in the middle of a stream with a minimum of delay. +
    • +
  • + Suitable for archiving: FLAC is an open format, and there is no generation loss if you need to convert your data to another format in the future. In addition to the frame CRCs and MD5 signature, flac has a verify option that decodes the encoded stream in parallel with the encoding process and compares the result to the original, aborting with an error if there is a mismatch. +
    • +
  • + Convenient CD archiving: FLAC has a "cue sheet" metadata block for storing a CD table of contents and all track and index points. For instance, you can rip a CD to a single file, then import the CD's extracted cue sheet while encoding to yield a single file representation of the entire CD. If your original CD is damaged, the cue sheet can be exported later in order to burn an exact copy. +
    • +
  • + Error resistant: Because of FLAC's framing, stream errors limit the damage to the frame in which the error occurred, typically a small fraction of a second worth of data. Contrast this with some other lossless codecs, in which a single error destroys the remainder of the stream. +
    • +
+ What FLAC is not: +
    +
  • + Lossy. FLAC is intended for lossless compression only, as there are many good lossy formats already, such as Vorbis, MPC, and MP3 (see LAME for an excellent open-source implementation). +
    • +
  • + DRM. There is no intention to add any copy prevention methods. Of course, we can't stop someone from encrypting a FLAC stream in another container (e.g. the way Apple encrypts AAC in MP4 with FairPlay), that is the choice of the user. +

+
+ This is a detailed description of the FLAC format. There is also a companion document that describes FLAC-to-Ogg mapping.
+
+ For a user-oriented overview, see About the FLAC Format.
+
+ Table of Contents + + Acknowledgments
+
+ FLAC owes much to the many people who have advanced the audio compression field so freely. For instance: +
    +
  • + A. J. Robinson for his work on Shorten; his paper is a good starting point on some of the basic methods used by FLAC. FLAC trivially extends and improves the fixed predictors, LPC coefficient quantization, and Rice coding used in Shorten. +
    • +
  • + S. W. Golomb and Robert F. Rice; their universal codes are used by FLAC's entropy coder. +
    • +
  • + N. Levinson and J. Durbin; the reference encoder uses an algorithm developed and refined by them for determining the LPC coefficients from the autocorrelation coefficients. +
    • +
  • + And of course, Claude Shannon +
    • +
+ Scope
+
+ It is a known fact that no algorithm can losslessly compress all possible input, so most compressors restrict themselves to a useful domain and try to work as well as possible within that domain. FLAC's domain is audio data. Though it can losslessly code any input, only certain kinds of input will get smaller. FLAC exploits the fact that audio data typically has a high degree of sample-to-sample correlation.
+
+ Within the audio domain, there are many possible subdomains. For example: low bitrate speech, high-bitrate multi-channel music, etc. FLAC itself does not target a specific subdomain but many of the default parameters of the reference encoder are tuned to CD-quality music data (i.e. 44.1kHz, 2 channel, 16 bits per sample). The effect of the encoding parameters on different kinds of audio data will be examined later.
+
+ Architecture
+
+ Similar to many audio coders, a FLAC encoder has the following stages: +
    +
  • + Blocking. The input is broken up into many contiguous blocks. With FLAC, the blocks may vary in size. The optimal size of the block is usually affected by many factors, including the sample rate, spectral characteristics over time, etc. Though FLAC allows the block size to vary within a stream, the reference encoder uses a fixed block size. +
    • +
  • + Interchannel Decorrelation. In the case of stereo streams, the encoder will create mid and side signals based on the average and difference (respectively) of the left and right channels. The encoder will then pass the best form of the signal to the next stage. +
    • +
  • + Prediction. The block is passed through a prediction stage where the encoder tries to find a mathematical description (usually an approximate one) of the signal. This description is typically much smaller than the raw signal itself. Since the methods of prediction are known to both the encoder and decoder, only the parameters of the predictor need be included in the compressed stream. FLAC currently uses four different classes of predictors (described in the prediction section), but the format has reserved space for additional methods. FLAC allows the class of predictor to change from block to block, or even within the channels of a block. +
    • +
  • + Residual coding. If the predictor does not describe the signal exactly, the difference between the original signal and the predicted signal (called the error or residual signal) must be coded losslessy. If the predictor is effective, the residual signal will require fewer bits per sample than the original signal. FLAC currently uses only one method for encoding the residual (see the Residual coding section), but the format has reserved space for additional methods. FLAC allows the residual coding method to change from block to block, or even within the channels of a block. +
    • +
+ In addition, FLAC specifies a metadata system, which allows arbitrary information about the stream to be included at the beginning of the stream.
+
+ Definitions
+
+ Many terms like "block" and "frame" are used to mean different things in differenct encoding schemes. For example, a frame in MP3 corresponds to many samples across several channels, whereas an S/PDIF frame represents just one sample for each channel. The definitions we use for FLAC follow. Note that when we talk about blocks and subblocks we are referring to the raw unencoded audio data that is the input to the encoder, and when we talk about frames and subframes, we are referring to the FLAC-encoded data. +
    +
  • + Block: One or more audio samples that span several channels. +
    • +
  • + Subblock: One or more audio samples within a channel. So a block contains one subblock for each channel, and all subblocks contain the same number of samples. +
    • +
  • + Blocksize: The number of samples in any of a block's subblocks. For example, a one second block sampled at 44.1KHz has a blocksize of 44100, regardless of the number of channels. +
    • +
  • + Frame: A frame header plus one or more subframes. +
    • +
  • + Subframe: A subframe header plus one or more encoded samples from a given channel. All subframes within a frame will contain the same number of samples. +
    • +
+ Blocking
+
+ The size used for blocking the audio data has a direct effect on the compression ratio. If the block size is too small, the resulting large number of frames mean that excess bits will be wasted on frame headers. If the block size is too large, the characteristics of the signal may vary so much that the encoder will be unable to find a good predictor. In order to simplify encoder/decoder design, FLAC imposes a minimum block size of 16 samples, and a maximum block size of 65535 samples. This range covers the optimal size for all of the audio data FLAC supports.
+
+ Currently the reference encoder uses a fixed block size, optimized on the sample rate of the input. Future versions may vary the block size depending on the characteristics of the signal.
+
+ Blocked data is passed to the predictor stage one subblock (channel) at a time. Each subblock is independently coded into a subframe, and the subframes are concatenated into a frame. Because each channel is coded separately, it means that one channel of a stereo frame may be encoded as a constant subframe, and the other an LPC subframe.
+
+ Interchannel Decorrelation
+
+ In stereo streams, many times there is an exploitable amount of correlation between the left and right channels. FLAC allows the frames of stereo streams to have different channel assignments, and an encoder may choose to use the best representation on a frame-by-frame basis. +
    +
  • + Independent. The left and right channels are coded independently. +
    • +
  • + Mid-side. The left and right channels are transformed into mid and side channels. The mid channel is the midpoint (average) of the left and right signals, and the side is the difference signal (left minus right). +
    • +
  • + Left-side. The left channel and side channel are coded. +
    • +
  • + Right-side. The right channel and side channel are coded +
    • +
+ Surprisingly, the left-side and right-side forms can be the most efficient in many frames, even though the raw number of bits per sample needed for the original signal is slightly more than that needed for independent or mid-side coding.
+
+ Prediction
+
+ FLAC uses four methods for modeling the input signal: +
    +
  • + Verbatim. This is essentially a zero-order predictor of the signal. The predicted signal is zero, meaning the residual is the signal itself, and the compression is zero. This is the baseline against which the other predictors are measured. If you feed random data to the encoder, the verbatim predictor will probably be used for every subblock. Since the raw signal is not actually passed through the residual coding stage (it is added to the stream 'verbatim'), the encoding results will not be the same as a zero-order linear predictor. +
    • +
  • + Constant. This predictor is used whenever the subblock is pure DC ("digital silence"), i.e. a constant value throughout. The signal is run-length encoded and added to the stream. +
    • +
  • + Fixed linear predictor. FLAC uses a class of computationally-efficient fixed linear predictors (for a good description, see audiopak and shorten). FLAC adds a fourth-order predictor to the zero-to-third-order predictors used by Shorten. Since the predictors are fixed, the predictor order is the only parameter that needs to be stored in the compressed stream. The error signal is then passed to the residual coder. +
    • +
  • + FIR Linear prediction. For more accurate modeling (at a cost of slower encoding), FLAC supports up to 32nd order FIR linear prediction (again, for information on linear prediction, see audiopak and shorten). The reference encoder uses the Levinson-Durbin method for calculating the LPC coefficients from the autocorrelation coefficients, and the coefficients are quantized before computing the residual. Whereas encoders such as Shorten used a fixed quantization for the entire input, FLAC allows the quantized coefficient precision to vary from subframe to subframe. The FLAC reference encoder estimates the optimal precision to use based on the block size and dynamic range of the original signal. +
    • +
+ Residual Coding
+
+ FLAC currently defines two similar methods for the coding of the error signal from the prediction stage. The error signal is coded using Rice codes in one of two ways: 1) the encoder estimates a single Rice parameter based on the variance of the residual and Rice codes the entire residual using this parameter; 2) the residual is partitioned into several equal-length regions of contiguous samples, and each region is coded with its own Rice parameter based on the region's mean. (Note that the first method is a special case of the second method with one partition, except the Rice parameter is based on the residual variance instead of the mean.)
+
+ The FLAC format has reserved space for other coding methods. Some possiblities for volunteers would be to explore better context-modeling of the Rice parameter, or Huffman coding. See LOCO-I and pucrunch for descriptions of several universal codes.
+
+ Format
+
+ This section specifies the FLAC bitstream format. FLAC has no format version information, but it does contain reserved space in several places. Future versions of the format may use this reserved space safely without breaking the format of older streams. Older decoders may choose to abort decoding or skip data encoded with newer methods. Apart from reserved patterns, in places the format specifies invalid patterns, meaning that the patterns may never appear in any valid bitstream, in any prior, present, or future versions of the format. These invalid patterns are usually used to make the synchronization mechanism more robust.
+
+ All numbers used in a FLAC bitstream are integers; there are no floating-point representations. All numbers are big-endian coded. All numbers are unsigned unless otherwise specified.
+
+ Before the formal description of the stream, an overview might be helpful. +
    +
  • + A FLAC bitstream consists of the "fLaC" marker at the beginning of the stream, followed by a mandatory metadata block (called the STREAMINFO block), any number of other metadata blocks, then the audio frames. +
    • +
  • + FLAC supports up to 128 kinds of metadata blocks; currently the following are defined: +
      +
    • STREAMINFO: This block has information about the whole stream, like sample rate, number of channels, total number of samples, etc. It must be present as the first metadata block in the stream. Other metadata blocks may follow, and ones that the decoder doesn't understand, it will skip.
      • +
    • APPLICATION: This block is for use by third-party applications. The only mandatory field is a 32-bit identifier. This ID is granted upon request to an application by the FLAC maintainers. The remainder is of the block is defined by the registered application. Visit the registration page if you would like to register an ID for your application with FLAC.
      • +
    • PADDING: This block allows for an arbitrary amount of padding. The contents of a PADDING block have no meaning. This block is useful when it is known that metadata will be edited after encoding; the user can instruct the encoder to reserve a PADDING block of sufficient size so that when metadata is added, it will simply overwrite the padding (which is relatively quick) instead of having to insert it into the right place in the existing file (which would normally require rewriting the entire file).
      • +
    • SEEKTABLE: This is an optional block for storing seek points. It is possible to seek to any given sample in a FLAC stream without a seek table, but the delay can be unpredictable since the bitrate may vary widely within a stream. By adding seek points to a stream, this delay can be significantly reduced. Each seek point takes 18 bytes, so 1% resolution within a stream adds less than 2k. There can be only one SEEKTABLE in a stream, but the table can have any number of seek points. There is also a special 'placeholder' seekpoint which will be ignored by decoders but which can be used to reserve space for future seek point insertion.
      • +
    • VORBIS_COMMENT: This block is for storing a list of human-readable name/value pairs. Values are encoded using UTF-8. It is an implementation of the Vorbis comment specification (without the framing bit). This is the only officially supported tagging mechanism in FLAC. There may be only one VORBIS_COMMENT block in a stream. In some external documentation, Vorbis comments are called FLAC tags to lessen confusion.
      • +
    • CUESHEET: This block is for storing various information that can be used in a cue sheet. It supports track and index points, compatible with Red Book CD digital audio discs, as well as other CD-DA metadata such as media catalog number and track ISRCs. The CUESHEET block is especially useful for backing up CD-DA discs, but it can be used as a general purpose cueing mechanism for playback.
      • +
    • PICTURE: This block is for storing pictures associated with the file, most commonly cover art from CDs. There may be more than one PICTURE block in a file. The picture format is similar to the APIC frame in ID3v2. The PICTURE block has a type, MIME type, and UTF-8 description like ID3v2, and supports external linking via URL (though this is discouraged). The differences are that there is no uniqueness constraint on the description field, and the MIME type is mandatory. The FLAC PICTURE block also includes the resolution, color depth, and palette size so that the client can search for a suitable picture without having to scan them all.
      • +
    +
    • +
  • + The audio data is composed of one or more audio frames. Each frame consists of a frame header, which contains a sync code, information about the frame like the block size, sample rate, number of channels, et cetera, and an 8-bit CRC. The frame header also contains either the sample number of the first sample in the frame (for variable-blocksize streams), or the frame number (for fixed-blocksize streams). This allows for fast, sample-accurate seeking to be performed. Following the frame header are encoded subframes, one for each channel, and finally, the frame is zero-padded to a byte boundary. Each subframe has its own header that specifies how the subframe is encoded. +
    • +
  • + Since a decoder may start decoding in the middle of a stream, there must be a method to determine the start of a frame. A 14-bit sync code begins each frame. The sync code will not appear anywhere else in the frame header. However, since it may appear in the subframes, the decoder has two other ways of ensuring a correct sync. The first is to check that the rest of the frame header contains no invalid data. Even this is not foolproof since valid header patterns can still occur within the subframes. The decoder's final check is to generate an 8-bit CRC of the frame header and compare this to the CRC stored at the end of the frame header. +
    • +
  • + Again, since a decoder may start decoding at an arbitrary frame in the stream, each frame header must contain some basic information about the stream because the decoder may not have access to the STREAMINFO metadata block at the start of the stream. This information includes sample rate, bits per sample, number of channels, etc. Since the frame header is pure overhead, it has a direct effect on the compression ratio. To keep the frame header as small as possible, FLAC uses lookup tables for the most commonly used values for frame parameters. For instance, the sample rate part of the frame header is specified using 4 bits. Eight of the bit patterns correspond to the commonly used sample rates of 8/16/22.05/24/32/44.1/48/96 kHz. However, odd sample rates can be specified by using one of the 'hint' bit patterns, directing the decoder to find the exact sample rate at the end of the frame header. The same method is used for specifying the block size and bits per sample. In this way, the frame header size stays small for all of the most common forms of audio data. +
    • +
  • + Individual subframes (one for each channel) are coded separately within a frame, and appear serially in the stream. In other words, the encoded audio data is NOT channel-interleaved. This reduces decoder complexity at the cost of requiring larger decode buffers. Each subframe has its own header specifying the attributes of the subframe, like prediction method and order, residual coding parameters, etc. The header is followed by the encoded audio data for that channel. +
    • +
  • + FLAC specifies a subset of itself as the Subset format. The purpose of this is to ensure that any streams encoded according to the Subset are truly "streamable", meaning that a decoder that cannot seek within the stream can still pick up in the middle of the stream and start decoding. It also makes hardware decoder implementations more practical by limiting the encoding parameters such that decoder buffer sizes and other resource requirements can be easily determined. flac generates Subset streams by default unless the "--lax" command-line option is used. The Subset makes the following limitations on what may be used in the stream: +
      +
    • + The blocksize bits in the frame header must be 0001-1110. The blocksize must be <=16384; if the sample rate is <= 48000Hz, the blocksize must be <=4608. +
      • +
    • + The sample rate bits in the frame header must be 0001-1110. +
      • +
    • + The bits-per-sample bits in the frame header must be 001-111. +
      • +
    • + If the sample rate is <= 48000Hz, the filter order in LPC subframes must be less than or equal to 12, i.e. the subframe type bits in the subframe header may not be 101100-111111. +
      • +
    • + The Rice partition order in a Rice-coded residual section must be less than or equal to 8. +
      • +
    +
    • +
+ + The following tables constitute a formal description of the FLAC format. Numbers in angle brackets indicate how many bits are used for a given field.

Given the stated purpose of vorbis comments, i.e. human-readable textual information, this limit is unlikely to be restrictive. Also note that the 32-bit field lengths are little-endian coded according to the vorbis spec, as opposed to the usual big-endian coding of fixed-length integers in the rest of FLAC. +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ METADATA_BLOCK_CUESHEET +
+ <128*8> + + Media catalog number, in ASCII printable characters 0x20-0x7e. In general, the media catalog number may be 0 to 128 bytes long; any unused characters should be right-padded with NUL characters. For CD-DA, this is a thirteen digit number, followed by 115 NUL bytes. +
+ <64> + + The number of lead-in samples. This field has meaning only for CD-DA cuesheets; for other uses it should be 0. For CD-DA, the lead-in is the TRACK 00 area where the table of contents is stored; more precisely, it is the number of samples from the first sample of the media to the first sample of the first index point of the first track. According to the Red Book, the lead-in must be silence and CD grabbing software does not usually store it; additionally, the lead-in must be at least two seconds but may be longer. For these reasons the lead-in length is stored here so that the absolute position of the first track can be computed. Note that the lead-in stored here is the number of samples up to the first index point of the first track, not necessarily to INDEX 01 of the first track; even the first track may have INDEX 00 data. +
+ <1> + + 1 if the CUESHEET corresponds to a Compact Disc, else 0. +
+ <7+258*8> + + Reserved. All bits must be set to zero. +
+ <8> + + The number of tracks. Must be at least 1 (because of the requisite lead-out track). For CD-DA, this number must be no more than 100 (99 regular tracks and one lead-out track). +
+ CUESHEET_TRACK+ + + One or more tracks. A CUESHEET block is required to have a lead-out track; it is always the last track in the CUESHEET. For CD-DA, the lead-out track number must be 170 as specified by the Red Book, otherwise is must be 255. +
+
+
+ +
+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ CUESHEET_TRACK +
+ <64> + + Track offset in samples, relative to the beginning of the FLAC audio stream. It is the offset to the first index point of the track. (Note how this differs from CD-DA, where the track's offset in the TOC is that of the track's INDEX 01 even if there is an INDEX 00.) For CD-DA, the offset must be evenly divisible by 588 samples (588 samples = 44100 samples/sec * 1/75th of a sec). +
+ <8> + + Track number. A track number of 0 is not allowed to avoid conflicting with the CD-DA spec, which reserves this for the lead-in. For CD-DA the number must be 1-99, or 170 for the lead-out; for non-CD-DA, the track number must for 255 for the lead-out. It is not required but encouraged to start with track 1 and increase sequentially. Track numbers must be unique within a CUESHEET. +
+ <12*8> + + Track ISRC. This is a 12-digit alphanumeric code; see here and here. A value of 12 ASCII NUL characters may be used to denote absence of an ISRC. +
+ <1> + + The track type: 0 for audio, 1 for non-audio. This corresponds to the CD-DA Q-channel control bit 3. +
+ <1> + + The pre-emphasis flag: 0 for no pre-emphasis, 1 for pre-emphasis. This corresponds to the CD-DA Q-channel control bit 5; see here. +
+ <6+13*8> + + Reserved. All bits must be set to zero. +
+ <8> + + The number of track index points. There must be at least one index in every track in a CUESHEET except for the lead-out track, which must have zero. For CD-DA, this number may be no more than 100. +
+ CUESHEET_TRACK_INDEX+ + + For all tracks except the lead-out track, one or more track index points. +
+
+
+ +
+ +
+
+ + + + + + + + + + + + + + + + +
+ CUESHEET_TRACK_INDEX +
+ <64> + + Offset in samples, relative to the track offset, of the index point. For CD-DA, the offset must be evenly divisible by 588 samples (588 samples = 44100 samples/sec * 1/75th of a sec). Note that the offset is from the beginning of the track, not the beginning of the audio data. +
+ <8> + + The index point number. For CD-DA, an index number of 0 corresponds to the track pre-gap. The first index in a track must have a number of 0 or 1, and subsequently, index numbers must increase by 1. Index numbers must be unique within a track. +
+ <3*8> + + Reserved. All bits must be set to zero. +

    +
  • + The "blocking strategy" bit must be the same throughout the entire stream. +
    • +
  • + The "blocking strategy" bit determines how to calculate the sample number of the first sample in the frame. If the bit is 0 (fixed-blocksize), the frame header encodes the frame number as above, and the frame's starting sample number will be the frame number times the blocksize. If it is 1 (variable-blocksize), the frame header encodes the frame's starting sample number itself. (In the case of a fixed-blocksize stream, only the last block may be shorter than the stream blocksize; its starting sample number will be calculated as the frame number times the previous frame's blocksize, or zero if it is the first frame). +
    • +
  • + The "UTF-8" coding used for the sample/frame number is the same variable length code used to store compressed UCS-2, extended to handle larger input. +

+
+ what is FLAC? +
+
+
+ FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.
+
+ FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.
+
+ See About FLAC for more, or Using FLAC for how to play FLAC files, rip CDs to FLAC, etc. +

+ Would you like iTunes to support FLAC? So would we!
+
+ Due to the design of iTunes, only Apple can add support for FLAC [1]. And why wouldn't they? FLAC usage is accelerating, many bands like Pearl Jam, Phish, Dave Matthews Band, Metallica -- the same hip, influential people whose fans Apple courts -- are already distributing music in FLAC format, and users are clamoring for it in the iTunes forums:
+
    +
  • [2] "I have seen a lot of people on live music message boards turn away from the iPod because there are other music players that support FLAC. I am on the verge... and I am an Apple die-hard!"
    • +
  • [3] "If your source material is FLAC (as many bands have gone this way to distribute online music) your choice is to use another music player ..."
    • +
  • [4] (many more requests)
    • +
+ Make your voice heard! Fill out the iTunes feedback form (politely!) and let them know. Feel free to also direct them to this page. We at the FLAC project stand ready to help as well.
+
+
+
+ [1] XiphQT, through tremendous effort by developers, goes as far as possible in allowing some playback capability via QuickTime. But proper iTunes support -- tag handling, no import delays, etc. -- is not possible without Apple.

+ license +
+
+
+ FLAC is a free codec in the fullest sense. This page explicitly states all that you may do with the format and software.
+
+ The FLAC and Ogg FLAC formats themselves, and their specifications, are fully open to the public to be used for any purpose (the FLAC project reserves the right to set the FLAC specification and certify compliance). They are free for commercial or noncommercial use. That means that commercial developers may independently write FLAC or Ogg FLAC software which is compatible with the specifications for no charge and without restrictions of any kind. There are no licensing fees or royalties of any kind for use of the formats or their specifications, or for distributing, selling, or streaming media in the FLAC or Ogg FLAC formats.
+
+ The FLAC project also makes available software that implements the formats, which is distributed according to Open Source licenses as follows:
+
+ The reference implementation libraries are licensed under the New BSD License. In simple terms, these libraries may be used by any application, Open or proprietary, linked or incorporated in whole, so long as acknowledgement is made to Xiph.org Foundation when using the source code in whole or in derived works. The Xiph License is free enough that the libraries have been used in commercial products to implement FLAC, including in the firmware of hardware devices where other Open Source licenses can be problematic. In the source code these libraries are called libFLAC and libFLAC++.
+
+ The rest of the software that the FLAC project provides is licensed under the GNU General Public License (GPL). This software includes various utilities for converting files to and from FLAC format, plugins for audio players, et cetera. In general, the GPL allows redistribution as long as derived works are also made available in source code form according to compatible terms.
+
+ Neither the FLAC nor Ogg FLAC formats nor any of the implemented encoding/decoding methods are covered by any known patent.
+
+ FLAC is one of a family of codecs of the Xiph.org Foundation, all created according to the same free ideals. For some other codecs' descriptions of the Xiph License see the Speex and Vorbis license pages.
+
+ If you would like to redistribute parts or all of FLAC under different terms, contact Josh Coalson. +

+ The links page is the place for all things FLAC. The hardware section lists the home stereo, car stereo, and portable devices that support the FLAC format. The music section has links to artists, labels, and legal trading/sharing sites that offer works encoded in FLAC. The software section is a loosely categorized list of open-source software that supports the FLAC format. Some of the most popular (some non-free) software can be found on the download page in the extras section. +

+ Reviews:
+ The main purpose of these reviews is to give an idea of how well particular devices support FLAC. Other subjective comments here are based on our general impressions and are not meant to be thorough or authoritative. We only review devices we have tested directly ourselves.
+
+ Sonos: A very slick networked audio system. Each ZonePlayer connects to an amplifier or speakers, accessing music over the network. ZonePlayers are controlled by a wireless remote with color LCD and clickwheel; they can network together wired or wireless and play in sync or independently. FLAC support is excellent; nearly the full subset (i.e. mono and stereo files, sample rates from 16kHz-48kHz, 16-bits per sample) including all standard encoding modes are supported. Also supported: gapless playback, FLAC tags, and ReplayGain.
+
+ Squeezebox: A fantastic networked audio player from Slim Devices with analog and digital outputs for connecting to an amplifier/receiver. Has an easy-to-read vacuum fluorescent display, wired or wireless networking, multi-room synchronization, and a bunch of other features. The server-side software, SlimServer, is open-source, runs on Windows, Mac OS X, Linux, etc. and has an active community. FLAC support is excellent; nearly the full subset (i.e. mono and stereo files, sample rates from 8kHz-48kHz, 16- and 24-bits per sample) including all standard encoding modes are supported. Also supported: gapless playback, FLAC tags, ReplayGain, automatic transcoding on the server of many audio formats to FLAC for transmission to the box, and external cuesheet support (internal cuesheet support is in the works).
+
+ Transporter: Top-of-the-line networked audio player from Slim Devices. Offers all the features of the Squeezebox (see just above), but loaded with pro-grade connectors (including balanced analog outputs and optical/coax/BNC/XLR digital ins and outs), top-end components, and a larger display. FLAC support is also excellent; all standard FLAC encoding modes and tags are supported, as are gapless playback, ReplayGain, cuesheets ... everything the Squeezebox supports, plus support for sample rates up to 96kHz.

    +
  • + FLAC has joined the Xiph project  See here for the press release.
    +
    + Xiph.org is behind other free codecs such as Vorbis, Theora, and Speex. Our merger with Xiph will bring FLAC into the ranks and lead to better integration with the Ogg multimedia framework.
    +
    + Note that the FLAC format is not changing, native FLAC will continue to exist, and the command-line tools and plugins will continue to work as before. The codec libraries will now be available under Xiph's BSD-like license.
    +
    + Over the next few days we will be transitioning normal operations off SourceForge and over to Xiph.org; first will be CVS and the web pages, followed by the mailing lists, bug tracker, and file release area. We will keep a mirror here until the transition is complete. It's OK to send patches to the flac-dev list but they won't be able to be integrated until CVS is fully moved over. +
    • +
+ + 26-Jan-2003: +
    +
  • + FLAC 1.1.0 released  I didn't get everything in that I wanted, but it's high time for a release.
    +
    + Note that the minor version has incremented, meaning forward compatibility was broken (forward compatibility means an earlier decoder can play all streams made by a later decoder). This is only because of a bug in 1.0.4 and prior where the decoder could not properly skip unknown metadata. The stream format itself has not changed and FLAC is still fully backward-compatible. All it means is that a FLAC file containing cue sheet metadata will not decode in older decoders. This bug is fixed in 1.1.0.
    +
    + Here's what's new:
    +
    + General: +
      +
    • All code is now Valgrind-clean!
      • +
    • New CUESHEET metadata block for storing CD TOC and index point information. Now a CD can be completely backed up to a single FLAC file for archival.
      • +
    • ReplayGain support.
      • +
    • Better compression of 24-bit files.
      • +
    • More complete AIFF support.
      • +
    • 3DNow! optimizations enabled by default.
      • +
    • Complete MSVC build system with .dsp projects for everything, which can build both static libs and DLLs, and in debug or release mode, all in the same source tree.
      • +
    + flac: +
      +
    • Can now decode FLAC to AIFF; new --force-aiff-format option.
      • +
    • New --cuesheet option for reading and storing a cuesheet when encoding a whole CD. Automatically creates seek points for track and index points unless --no-cued-seekpoints is used.
      • +
    • New --replay-gain option for calculating ReplayGain values and storing them as tags.
      • +
    • New --until option complements --skip to stop decoding at a specified point in the stream.
      • +
    • --skip and --until now also accept mm:ss.ss format.
      • +
    • New -S #s flavor to specify seekpoints every '#' number of seconds.
      • +
    • flac now defaults to -S 10s instead of -S 100x for the seek table.
      • +
    • flac now adds a 4k PADDING block by default (turn off with --no-padding).
      • +
    • Fixed a bug with --skip and AIFF-to-FLAC encoding.
      • +
    • Fixed a bug where decoding a FLAC file whose total_samples==0 in the STREAMINFO would corrupt the WAVE header.
      • +
    + metaflac: +
      +
    • New --import-cuesheet-from option for reading and storing a cuesheet to a FLAC-encoded CD. Automatically creates seek points for track and index points unless --no-cued-seekpoints is used.
      • +
    • New --export-cuesheet-to option for writing a cuesheet from a FLAC file for use with CD authoring software.
      • +
    • New --add-replay-gain option for calculating ReplayGain values and storing them as tags.
      • +
    • New --add-seekpoint option to add seekpoints to an existing FLAC file. Includes new --add-seekpoint=#s flavor to add seekpoints every '#' number of seconds.
      • +
    + XMMS plugin: +
      +
    • Configurable sample resolution conversion with dither.
      • +
    • ReplayGain support with customizable noise shaping, pre-amp, and optional hard limiter.
      • +
    • New Vorbis comment editor.
      • +
    • File info now works.
      • +
    • Bitrate now shows the smoothed instantaneous bitrate.
      • +
    • Uses the ARTIST tag if there is no PERFORMER tag.
      • +
    + Winamp2 plugin: +
      +
    • Configurable sample resolution conversion with dither.
      • +
    • ReplayGain support with customizable noise shaping, pre-amp, and optional hard limiter.
      • +
    • File info now works.
      • +
    • Uses the ARTIST tag if there is no PERFORMER tag.
      • +
    + Libraries (developers take note!): +
      +
    • All code and tests are instrumented for Valgrind. All tests run Valgrind-clean, meaning no memory leaks or buffer over/under-runs.
      • +
    • Separate 64-bit datapath through the filter in libFLAC for better compression of >16 bps files.
      • +
    • FLAC__metadata_object_new(FLAC__METADATA_TYPE_VORBIS_COMMENT) now sets the vendor string.
      • +
    • The documentation on the usage of FLAC::Iterator::get_block() in libFLAC++ has an important correction. If you use this class make sure to read this.
      • +
    +
    • +
+ + 24-Sep-2002: +
    +
  • + FLAC 1.0.4 released  There are a lot of improvements since 1.0.3; let's get right to it:
    +
    + Plugins: +
      +
    • Support for Vorbis comments, ID3 v1 and v2 tags.
      • +
    • Configurable title formatting and charset conversion in XMMS plugin.
      • +
    • Support for 8- and 24-bit FLAC files. There is a compile-time option for raw 24-bit output or 24bps-to-16bps linear dithering (the default).
      • +
    + flac: +
      +
    • Improved option parser (now uses getopt).
      • +
    • AIFF input support (thanks to Brady Patterson).
      • +
    • Small decoder speedup.
      • +
    • --sector-align now supported for raw input files.
      • +
    • New -T, --tag options for adding Vorbis comments while encoding.
      • +
    • New --serial-number option for use with --ogg.
      • +
    • Automatically writes vendor string in Vorbis comments.
      • +
    • Drastically reduced memory requirements.
      • +
    • Fixed bug where extra fmt/data chunks that were supposed to be skipped were not getting skipped.
      • +
    • Fixed bug in granulepos setting for Ogg FLAC streams.
      • +
    • Fixed memory leak when encoding multiple files with -V.
      • +
    + metaflac: +
      +
    • UTF-8 support in Vorbis comments.
      • +
    • New --import-vc-from and --export-vc-to commands for importing/exporting Vorbis comments from/to a file. For example, the following can be used to copy tags back and forth:
      + + metaflac --export-vc-to=- --no-utf8-convert file.flac | vorbiscomment --raw -w file.ogg
      + vorbiscomment --raw -l file.ogg | metaflac --import-vc-from=- --no-utf8-convert file.flac
      +       +
      • +
    • Fixed bug #606796 where metaflac was failing on read-only files.
      • +
    + Libraries: +
      +
    • All APIs now meticulously documented via Doxygen. See here.
      • +
    • New libOggFLAC and libOggFLAC++ libraries. These wrap around libFLAC to provide encoding and decoding of Ogg FLAC streams, providing interfaces similar to the ones of the native FLAC libraries. These are also documented via Doxygen.
      • +
    • New FLAC__SeekableStreamEncoder and FLAC__FileEncoder in libFLAC simplify common encoding tasks.
      • +
    • New verify mode in all encoders.
      • +
    • FLAC__stream_encoder_finish() now resets the defaults just like the stream decoders.
      • +
    • Drastically reduced memory requirements of encoders and decoders.
      • +
    • Encoder now automatically writes vendor string in VORBIS_COMMENT block.
      • +
    • Encoding speedup of fixed predictors and MD5 speedup for 16bps mono/stereo signals on x86 (thanks to Miroslav Lichvar).
      • +
    • Fixed bug in metadata interface where a bps in STREAMINFO > 16 was incorrectly parsed.
      • +
    • Fixed bug where aborting stream decoder could cause infinite loop.
      • +
    • Behavior change: simplified decoder *_process() commands.
      • +
    • Behavior change: calling FLAC__stream_encoder_init() calls write callback once for "fLaC" signature and once for each metadata block.
      • +
    • Behavior change: deprecated do_escape_coding and rice_parameter_search_distance in encoder.
      • +
    +
    • +
+ + 22-Aug-2002: +
    +
  • + Rio Receiver  FLAC support has been added to the Rio Receiver and Dell Digital Audio Receiver via David Flowerday's RioPlay client. See here for the announcement. +
    • +
+ + 03-Jul-2002: +
    +
  • + FLAC 1.0.3 released  Although by version number only a 0.0.1 increment, this release is significant. Remember, micro-revisions mean the FLAC format remains both forward and backward compatible, however, the libFLAC API has changed for the better.
    +
    + New features: +
      +
    • 24-bit input support restored in flac.
      • +
    • Decoder speedup in libFLAC, which is directly passed on to the command-line decoder and plugins.
      • +
    • New -F option to flac to continue decoding in spite of errors.

      • +
    • Fixed bug in Ogg packet numbering.
      • +
    +
    • +
+ + 13-Feb-2002: +
    +
  • + FLAC goes hardware!  PhatNoise has become the first commercial hardware platform to support FLAC. Firmware is now available for the Phatbox player to play FLAC files. See here for details. +
    • +
+ + 03-Dec-2001: +
    +
  • + FLAC 1.0.2 released  This release is only to fix a bug that was causing some of the plugins to crash sporadically. It can also affect libFLAC users that reuse one file decoder instance for multiple files; see here for more. +
    • +
+ + 14-Nov-2001: +
    +
  • + FLAC 1.0.1 released  The core codec is unchanged but there have been some features added and some bugs fixed:
    +
    + New features for users: +
      +
    • Support for Ogg-FLAC, i.e. flac can now read and write FLAC streams using Ogg as the transport layer.
      • +
    • New Winamp 3 plugin based on the Wasabi Beta 1 SDK.
      • +
    • New utilities for adding FLAC support to the Monkey's Audio GUI (see how).
      • +
    • Mac OS X support. The download area now contains an OS X binary release.
      • +
    • Mingw32 support.
      • +
    • Better handling of MS-specific 'fmt' chunks in WAVE files.
      • +
    + New features for developers: +
      +
    • Added a SeekableStreamDecoder layer between StreamDecoder and FileDecoder. This makes it easier to use libFLAC in situations where files have been abstracted away. See the latest documentation for more. The interface for the StreamDecoder and FileDecoder remain the same and are still binary-compatible with libFLAC 1.0.
      • +
    • Drastically reduced the stack requirements of the encoder.
      • +
    + Bug fixes: +
      +
    • Fixed a serious bug with flac and raw input where the encoder was trying to rewind when it shouldn't, which would add 12 junk samples to the encoded file. This was not present in WAVE encoding.
      • +
    • Fixed a minor bug in libFLAC with setting the file name to stdin on a file decoder.
      • +
    • Fixed a minor bug in libFLAC where multiple calls to setting the file name on a file decoder caused leaked memory.
      • +
    • Fixed a minor bug in metaflac, now correctly skips an id3v2 tag if present.
      • +
    • Fixed a minor bug in metaflac, now correctly skips long metadata blocks.
      • +
    +
    • +
+ + 20-Jul-2001: +
    +
  • + FLAC 1.0 is out!  It's finally here. There are a few new features but mostly it is minor bug fixes since 0.10: +
      +
    • New '--sector-align' option to flac which aligns a group of encoded files on CD audio sector boundaries.
      • +
    • New '--output-prefix' option to flac to allow the user to prepend a prefix to all output filenames (useful, for example, for encoding/decoding to a different directory).
      • +
    • Better WAVE autodetection (doesn't rely on ungetc() anymore).
      • +
    • Cleaner one-line encoding/decoding stats.
      • +
    • Changes to the libFLAC interface and type names to make binary compatibility easier to maintain in the future.
      • +
    • New '--sse-os' option to 'configure' to enable faster SSE-based routines.
      • +
    • Another (hopefully last) fix to the Winamp 2 plugin.
      • +
    • Slightly improved Rice parameter estimation.
      • +
    • Bug fixes for some very rare corner cases when encoding.
      • +
    +
    • +
+ + 07-Jun-2001: +
    +
  • + FLAC 0.10 released.  This is probably the final beta. There have been many improvements in the last two months: +
      +
    • Both the encoder and decoder have been significantly sped up. Aside from C improvements, the code base now has an assembly infrastructure that allows assembly routines for different architectures to be easily integrated. Many key routines have now have faster IA-32 implementations (thanks to Miroslav).
      • +
    • A new metadata block SEEKTABLE has been defined to hold an arbitrary number of seek points, which speeds up seeking within a stream.
      • +
    • flac now has a command-line usage similar to 'gzip'; make sure to see the latest documentation for the new usage. It also attempts to preserve the input file's timestamp and permissions.
      • +
    • The -# options in flac have been tweaked to yield the best compression-to-encode-time ratios. The new default is -5.
      • +
    • flac can now usually autodetect WAVE files when encoding so that -fw is usually not needed when encoding from stdin.
      • +
    • The WAVE reader in flac now just ignores (with a warning) unsupported sub-chunks instead of aborting with an error.
      • +
    • Added an option '--delete-input-file' to flac which automatically deletes the input after a successful encode/decode.
      • +
    • Added an option '-o' to flac to force the output file name (the old usage of "flac - outputfilename" is no longer supported).
      • +
    • Changed the XMMS plugin to send smaller chunks of samples (now 512) so that visualization is not slow.
      • +
    • Fixed a bug in the stream decoder where the decoded samples counter got corrupted after a seek.
      • +
    + It should be a short hop to 1.0. +
    • +
+ + 31-Mar-2001: +
    +
  • + FLAC 0.9 released.  There were some format changes that broke backwards compatibility but these should be the last (see below). Also, there have been several bug fixes and some new features: +
      +
    • FLAC's sync code has been lengthened to 14 bits from 9 bits. This should enable a faster and more robust synchronization mechanism.
      • +
    • Two reserved bits were added to the frame header.
      • +
    • A CRC-16 was added to the FLAC frame footer, and the decoder now does frame integrity checking based on the CRC.
      • +
    • The format now includes a new subframe field to indicate when a subblock has one or more 0 LSBs for all samples. This increases compression on some kinds of data.
      • +
    • Added two options to the analysis mode, one for including the residual signal in the analysis file, and one for generating gnuplot files of each subframe's residual distribution with some statistics. See the latest documentation.
      • +
    • XMMS plugin now supports 8-bit files.
      • +
    • Fixed a bug in the Winamp2 plugin where the audio sounded garbled.
      • +
    • Fixed a bug in the Winamp2 plugin where Winamp would hang sporadically at the end of a track (c.f. bug #231197).
      • +
    + FLAC is on track for an official 1.0 release soon. +
    • +
+ + 05-Mar-2001: +
    +
  • + FLAC 0.8 released.  This release is a result of extensive testing and fixes several bugs encountered when pushing the encoder to the limit. I'm pretty confident in the stability of the encoder/decoder now for all kinds of input. There have also been several features added. Here is a complete list of the changes since 0.7: +
      +
    • Created a new utility called metaflac. It is a metadata editor for .flac files. Right now it just lists the contents of the metadata blocks but eventually it will allow update/insertion/deletion.
      • +
    • Added two new metadata blocks: PADDING which has an obvious function, and APPLICATION, which is meant to be open to third party applications. See the latest format docs for more info, or the new id registration page.
      • +
    • Added a -P option to flac to reserve a PADDING block when encoding.
      • +
    • Added support for 24-bit files to flac (the FLAC format always supported it).
      • +
    • Started the Winamp3 plugin.
      • +
    • Greatly expanded the test suite, adding more streams (24-bit streams, noise streams, non-audio streams, more patterns) and more option combinations to the encoder. The test suite runs about 30 streams and over 5000 encodings now.
      • +
    • Fixed a bug in libFLAC that happened when using an exhaustive LPC coefficient quantization search with 8 bps input.
      • +
    • Fixed a bug in libFLAC where the error estimation in the fixed predictor could overflow.
      • +
    • Fixed a bug in libFLAC where LPC was attempted even when the autocorrelation coefficients implied it wouldn't help.
      • +
    • Reworked the LPC coefficient quantizer, which also fixed another bug that might occur in rare cases.
      • +
    • Really fixed the '-V overflow' bug (c.f. bug #231976).
      • +
    • Fixed a bug in flac related to the decode buffer sizing.
      • +
    + FLAC is very close to being ready for an official release. The only known problems left are with the Winamp plugins, which should be fixed soon, and pipes with MSVC. +
    • +
+ + 12-Feb-2001: +
    +
  • + FLAC 0.7 released.  This is mainly a bug fix release, specifically: +
      +
    • Fixed a bug that happened when both -fr and --seek were used at the same time.
      • +
    • Fixed a bug with -p (c.f. bug #230992).
      • +
    • Fixed a bug that happened when using large (>32K) blocksizes and -V (c.f. bug #231976).
      • +
    • Fixed a bug where encoder was double-closing a file.
      • +
    • Expanded the test suite.
      • +
    • Added more optimization flags for gcc, which should speed up flac.
      • +
    +
    • +
+ + 28-Jan-2001: +
    +
  • + FLAC 0.6 released.  The encoder is now much faster. The -m option has been sped up by 4x and -r improved, meaning that in the default compression mode (-6), encoding should be at least 3 times faster. Other changes: +
      +
    • Some bugs related to flac and pipes were fixed (see here for the discussion).
      • +
    • A "loose mid-side" (-M) option to the encoder has been added, which adaptively switches between independent and mid-side coding, instead of the exhaustive search that -m does.
      • +
    • An analyze mode (-a) has been added to flac. This is useful mainly for developers; currently it will dump info about each frame and subframe to a file. It's a text file in a format that can be easily processed by scripts; a separate analysis program is in the works.
      • +
    • The source now has an autoconf/libtool-based build system. This should allow the source to build "out-of-the-box" on many more platforms.
      • +
    +
    • +
+ + 15-Jan-2001: +
    +
  • + FLAC 0.5 released.  This is the first beta version of FLAC. Being beta, there will be no changes to the format that will break older streams, unless a serious bug involving the format is found. What this means is that, barring such a bug, streams created with 0.5 will be decodable by future versions. This version also includes some new features: +
      +
    • An MD5 signature of the unencoded audio is computed during encoding, and stored in the Encoding metadata block in the stream header. When decoding, flac will now compute the MD5 signature of the decoded data and compare it against the signature in the stream header.
      • +
    • A test mode (-t) has been added to flac. It works like decode mode but doesn't write an output file.
      • +
    +
    • +
+ + 23-Dec-2000: +
    +
  • FLAC 0.4 released.  This version fixes a bug in the constant subframe detection. More importantly, a verify option (-V) has been added to flac that verifies the encoding process. With this option turned on, flac will create a parallel decoder while encoding to make sure that the encoded output decodes to exactly match the original input. In this way, any unknown bug in the encoder will be caught and flac will abort with an error message.
    • +
+ + 10-Dec-2000: +
    +
  • FLAC debuts on SourceForge.  The FLAC project is now being hosted on SourceForge. Visit the FLAC project page to join the mailing list or sign up as a developer.

+
+ ogg mapping +
+
+
+ This page specifies the way in which compressed FLAC data is encapsulated in an Ogg transport layer. It assumes basic knowledge of the FLAC format and Ogg structure and framing.
+
+ The original FLAC format includes a very thin transport system. This system of compressed FLAC audio data mixed with a thin transport has come to be known as 'native FLAC'. The transport consists of audio frame headers and footers which contain synchronization patterns, timecodes, and checksums (but notably not frame lengths), and a metadata system. It is very lightweight and does not support more elaborate transport mechanisms such as multiple logical streams, but it has served its purpose well.
+
+ The native FLAC transport is not a transport "layer" in the way of standard codec design because it cannot be entirely separated from the payload. Though the metadata system can be separated, the frame header includes both data that belongs in the transport (sync pattern, timecode, checksum) and data that belongs in the compressed packets (audio parameters like channel assignments, sample rate, etc).
+
+ This presents a problem when trying to encapsulate FLAC in other true transport layers; the choice has to be made between redundancy and complexity. In pursuit of correctness, a mapping could be created that removed from native FLAC the transport data, and merged the remaining frame header information into the audio packets. The disadvantage is that current native FLAC decoder software could not be used to decode because of the tight coupling with the transport. Either a separate decoding implementation would have to be created and maintained, or an Ogg FLAC decoder would have to synthesize native FLAC frames from Ogg FLAC packets and feed them to a native FLAC decoder.
+
+ The alternative is to treat native FLAC frames as Ogg packets and accept the transport redundancy. It turns out that this is not much of a penalty; a maximum of 12 bytes per frame will be wasted. Given the common case of stereo CD audio encoded with a blocksize of 4096 samples, a compressed frame will be 4-16 Kbytes. The redundancy amounts to a fraction of a percent.
+
+ In the interest of simplicity and expediency, the second method was chosen for the first official FLAC->Ogg mapping. A mapping version is included in the first packet so that a less redundant mapping can be defined in the future.
+
+ It should also be noted that support for encapsulating FLAC in Ogg has been present in the FLAC tools since version 1.0.1. However, the mappings used were never formalized and have insurmountable problems. For that reason, Ogg FLAC streams created with flac versions before 1.1.1 should be decoded and re-encoded with flac 1.1.1 or later (flac 1.1.1 can decode all previous Ogg FLAC files, but files made prior to 1.1.0 don't support seeking). Since the support for Ogg FLAC before FLAC 1.1.1 was limited, we hope this will not result in too much inconvenience.
+
+ Version 1.0 of the FLAC-to-Ogg mapping then is a simple identifying header followed by pure native FLAC data, as follows: +
    +
  • + The first packet of a stream consists of: +
      +
    • The one-byte packet type 0x7F
      • +
    • The four-byte ASCII signature "FLAC", i.e. 0x46, 0x4C, 0x41, 0x43
      • +
    • A one-byte binary major version number for the mapping, e.g. 0x01 for mapping version 1.0
      • +
    • A one-byte binary minor version number for the mapping, e.g. 0x00 for mapping version 1.0
      • +
    • A two-byte, big-endian binary number signifying the number of header (non-audio) packets, not including this one. This number may be zero (0x0000) to signify 'unknown' but be aware that some decoders may not be able to handle such streams.
      • +
    • The four-byte ASCII native FLAC signature "fLaC" according to the FLAC format specification
      • +
    • The STREAMINFO metadata block for the stream.
      • +
    + This first packet is the only packet in the first page of the stream. This results in a first Ogg page of exactly 79 bytes at the very beginning of the logical stream. +
    • +
  • + This first page is marked 'beginning of stream' in the page flags. +
    • +
  • + The first packet is followed by one or more header packets. Each such packet will contain a single native FLAC metadata block. The first of these must be a VORBIS_COMMENT block. These packets may span page boundaries but the last will finish the page on which it ends, so that the first audio packet begins a page. The first byte of these metadata packets serves also as the packet type, and has a legal range of (0x01-0x7E,0x81-0xFE). +
    • +
  • + The granule position of these first pages containing only headers is zero. +
    • +
  • + The first audio packet of the logical stream begins a fresh Ogg page. +
    • +
  • + Native FLAC audio frames appear as subsequent packets in the stream. Each packet corresponds to one FLAC audio frame. The first byte of each packet serves as the packet type. Since audio packets are native FLAC frames, this first byte will be always 0xFF according to the native FLAC format specification. +
    • +
  • + The last page is marked 'end of stream' in the page flags. +
    • +
  • + FLAC packets may span page boundaries. +
    • +
  • + The granule position of pages containing FLAC audio follows the same semantics as that for Ogg-encapsulated Vorbis as described here. +
    • +
  • + Redundant fields in the STREAMINFO packet may be set to zero (indicating "unknown" in native FLAC), which also facilitates single-pass encoding. These fields are: the minimum and maximum frame sizes, the total samples count, and the MD5 signature. "Unknown" values for these fields will not prevent a compliant native FLAC or Ogg FLAC decoder from decoding the stream. +
    • +
+ It is intended that the first six bytes of any version of FLAC-to-Ogg mapping will share the same structure, namely, the four-byte signature and two-byte version number.
+
+ There is an implicit hint to the decoder in the mapping version number; mapping versions which share the same major version number should be decodable by decoders of the same major version number, e.g. a 1.x Ogg FLAC decoder should be able to decode any 1.y Ogg FLAC stream, even when x<y. If a mapping breaks this forward compatibility the major version number will be incremented. +

It is + * highly interconnected; this introduction should give you a top + * level idea of the structure and how to find the information you + * need. As a prerequisite you should have at least a basic + * knowledge of the FLAC format, documented + * here. + * + * \section c_api FLAC C API + * + * The FLAC C API is the interface to libFLAC, a set of structures + * describing the components of FLAC streams, and functions for + * encoding and decoding streams, as well as manipulating FLAC + * metadata in files. The public include files will be installed + * in your include area (for example /usr/include/FLAC/...). + * + * By writing a little code and linking against libFLAC, it is + * relatively easy to add FLAC support to another program. The + * library is licensed under Xiph's BSD license. + * Complete source code of libFLAC as well as the command-line + * encoder and plugins is available and is a useful source of + * examples. + * + * Aside from encoders and decoders, libFLAC provides a powerful + * metadata interface for manipulating metadata in FLAC files. It + * allows the user to add, delete, and modify FLAC metadata blocks + * and it can automatically take advantage of PADDING blocks to avoid + * rewriting the entire FLAC file when changing the size of the + * metadata. + * + * libFLAC usually only requires the standard C library and C math + * library. In particular, threading is not used so there is no + * dependency on a thread library. However, libFLAC does not use + * global variables and should be thread-safe. + * + * libFLAC also supports encoding to and decoding from Ogg FLAC. + * However the metadata editing interfaces currently have limited + * read-only support for Ogg FLAC files. + * + * \section cpp_api FLAC C++ API + * + * The FLAC C++ API is a set of classes that encapsulate the + * structures and functions in libFLAC. They provide slightly more + * functionality with respect to metadata but are otherwise + * equivalent. For the most part, they share the same usage as + * their counterparts in libFLAC, and the FLAC C API documentation + * can be used as a supplement. The public include files + * for the C++ API will be installed in your include area (for + * example /usr/include/FLAC++/...). + * + * libFLAC++ is also licensed under + * Xiph's BSD license. + * + * \section getting_started Getting Started + * + * A good starting point for learning the API is to browse through + * the modules. Modules are logical + * groupings of related functions or classes, which correspond roughly + * to header files or sections of header files. Each module includes a + * detailed description of the general usage of its functions or + * classes. + * + * From there you can go on to look at the documentation of + * individual functions. You can see different views of the individual + * functions through the links in top bar across this page. + * + * If you prefer a more hands-on approach, you can jump right to some + * example code. + * + * \section porting_guide Porting Guide + * + * Starting with FLAC 1.1.3 a \link porting Porting Guide \endlink + * has been introduced which gives detailed instructions on how to + * port your code to newer versions of FLAC. + * + * \section embedded_developers Embedded Developers + * + * libFLAC has grown larger over time as more functionality has been + * included, but much of it may be unnecessary for a particular embedded + * implementation. Unused parts may be pruned by some simple editing of + * src/libFLAC/Makefile.am. In general, the decoders, encoders, and + * metadata interface are all independent from each other. + * + * It is easiest to just describe the dependencies: + * + * - All modules depend on the \link flac_format Format \endlink module. + * - The decoders and encoders depend on the bitbuffer. + * - The decoder is independent of the encoder. The encoder uses the + * decoder because of the verify feature, but this can be removed if + * not needed. + * - Parts of the metadata interface require the stream decoder (but not + * the encoder). + * - Ogg support is selectable through the compile time macro + * \c FLAC__HAS_OGG. + * + * For example, if your application only requires the stream decoder, no + * encoder, and no metadata interface, you can remove the stream encoder + * and the metadata interface, which will greatly reduce the size of the + * library. + * + * Also, there are several places in the libFLAC code with comments marked + * with "OPT:" where a #define can be changed to enable code that might be + * faster on a specific platform. Experimenting with these can yield faster + * binaries. + */ + +/** \defgroup porting Porting Guide for New Versions + * + * This module describes differences in the library interfaces from + * version to version. It assists in the porting of code that uses + * the libraries to newer versions of FLAC. + * + * One simple facility for making porting easier that has been added + * in FLAC 1.1.3 is a set of \c #defines in \c export.h of each + * library's includes (e.g. \c include/FLAC/export.h). The + * \c #defines mirror the libraries' + * libtool version numbers, + * e.g. in libFLAC there are \c FLAC_API_VERSION_CURRENT, + * \c FLAC_API_VERSION_REVISION, and \c FLAC_API_VERSION_AGE. + * These can be used to support multiple versions of an API during the + * transition phase, e.g. + * + * \code + * #if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7 + * legacy code + * #else + * new code + * #endif + * \endcode + * + * The the source will work for multiple versions and the legacy code can + * easily be removed when the transition is complete. + * + * Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in + * include/FLAC/export.h), which can be used to determine whether or not + * the library has been compiled with support for Ogg FLAC. This is + * simpler than trying to call an Ogg init function and catching the + * error. + */ + +/** \defgroup porting_1_1_2_to_1_1_3 Porting from FLAC 1.1.2 to 1.1.3 + * \ingroup porting + * + * \brief + * This module describes porting from FLAC 1.1.2 to FLAC 1.1.3. + * + * The main change between the APIs in 1.1.2 and 1.1.3 is that they have + * been simplified. First, libOggFLAC has been merged into libFLAC and + * libOggFLAC++ has been merged into libFLAC++. Second, both the three + * decoding layers and three encoding layers have been merged into a + * single stream decoder and stream encoder. That is, the functionality + * of FLAC__SeekableStreamDecoder and FLAC__FileDecoder has been merged + * into FLAC__StreamDecoder, and FLAC__SeekableStreamEncoder and + * FLAC__FileEncoder into FLAC__StreamEncoder. Only the + * FLAC__StreamDecoder and FLAC__StreamEncoder remain. What this means + * is there is now a single API that can be used to encode or decode + * streams to/from native FLAC or Ogg FLAC and the single API can work + * on both seekable and non-seekable streams. + * + * Instead of creating an encoder or decoder of a certain layer, now the + * client will always create a FLAC__StreamEncoder or + * FLAC__StreamDecoder. The old layers are now differentiated by the + * initialization function. For example, for the decoder, + * FLAC__stream_decoder_init() has been replaced by + * FLAC__stream_decoder_init_stream(). This init function takes + * callbacks for the I/O, and the seeking callbacks are optional. This + * allows the client to use the same object for seekable and + * non-seekable streams. For decoding a FLAC file directly, the client + * can use FLAC__stream_decoder_init_file() and pass just a filename + * and fewer callbacks; most of the other callbacks are supplied + * internally. For situations where fopen()ing by filename is not + * possible (e.g. Unicode filenames on Windows) the client can instead + * open the file itself and supply the FILE* to + * FLAC__stream_decoder_init_FILE(). The init functions now returns a + * FLAC__StreamDecoderInitStatus instead of FLAC__StreamDecoderState. + * Since the callbacks and client data are now passed to the init + * function, the FLAC__stream_decoder_set_*_callback() functions and + * FLAC__stream_decoder_set_client_data() are no longer needed. The + * rest of the calls to the decoder are the same as before. + * + * There are counterpart init functions for Ogg FLAC, e.g. + * FLAC__stream_decoder_init_ogg_stream(). All the rest of the calls + * and callbacks are the same as for native FLAC. + * + * As an example, in FLAC 1.1.2 a seekable stream decoder would have + * been set up like so: + * + * \code + * FLAC__SeekableStreamDecoder *decoder = FLAC__seekable_stream_decoder_new(); + * if(decoder == NULL) do_something; + * FLAC__seekable_stream_decoder_set_md5_checking(decoder, true); + * [... other settings ...] + * FLAC__seekable_stream_decoder_set_read_callback(decoder, my_read_callback); + * FLAC__seekable_stream_decoder_set_seek_callback(decoder, my_seek_callback); + * FLAC__seekable_stream_decoder_set_tell_callback(decoder, my_tell_callback); + * FLAC__seekable_stream_decoder_set_length_callback(decoder, my_length_callback); + * FLAC__seekable_stream_decoder_set_eof_callback(decoder, my_eof_callback); + * FLAC__seekable_stream_decoder_set_write_callback(decoder, my_write_callback); + * FLAC__seekable_stream_decoder_set_metadata_callback(decoder, my_metadata_callback); + * FLAC__seekable_stream_decoder_set_error_callback(decoder, my_error_callback); + * FLAC__seekable_stream_decoder_set_client_data(decoder, my_client_data); + * if(FLAC__seekable_stream_decoder_init(decoder) != FLAC__SEEKABLE_STREAM_DECODER_OK) do_something; + * \endcode + * + * In FLAC 1.1.3 it is like this: + * + * \code + * FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new(); + * if(decoder == NULL) do_something; + * FLAC__stream_decoder_set_md5_checking(decoder, true); + * [... other settings ...] + * if(FLAC__stream_decoder_init_stream( + * decoder, + * my_read_callback, + * my_seek_callback, // or NULL + * my_tell_callback, // or NULL + * my_length_callback, // or NULL + * my_eof_callback, // or NULL + * my_write_callback, + * my_metadata_callback, // or NULL + * my_error_callback, + * my_client_data + * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; + * \endcode + * + * or you could do; + * + * \code + * [...] + * FILE *file = fopen("somefile.flac","rb"); + * if(file == NULL) do_somthing; + * if(FLAC__stream_decoder_init_FILE( + * decoder, + * file, + * my_write_callback, + * my_metadata_callback, // or NULL + * my_error_callback, + * my_client_data + * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; + * \endcode + * + * or just: + * + * \code + * [...] + * if(FLAC__stream_decoder_init_file( + * decoder, + * "somefile.flac", + * my_write_callback, + * my_metadata_callback, // or NULL + * my_error_callback, + * my_client_data + * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; + * \endcode + * + * Another small change to the decoder is in how it handles unparseable + * streams. Before, when the decoder found an unparseable stream + * (reserved for when the decoder encounters a stream from a future + * encoder that it can't parse), it changed the state to + * \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM. Now the decoder instead + * drops sync and calls the error callback with a new error code + * \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM. This is + * more robust. If your error callback does not discriminate on the the + * error state, your code does not need to be changed. + * + * The encoder now has a new setting: + * FLAC__stream_encoder_set_apodization(). This is for setting the + * method used to window the data before LPC analysis. You only need to + * add a call to this function if the default is not suitable.

This level is write- + * efficient in most cases (more on this below), and uses less memory + * than level 2. + * + * Level 2: + * Read-write access to all metadata blocks. This level is write- + * efficient in all cases, but uses more memory since all metadata for + * the whole file is read into memory and manipulated before writing + * out again. + * + * What do we mean by efficient? Since FLAC metadata appears at the + * beginning of the file, when writing metadata back to a FLAC file + * it is possible to grow or shrink the metadata such that the entire + * file must be rewritten. However, if the size remains the same during + * changes or PADDING blocks are utilized, only the metadata needs to be + * overwritten, which is much faster. + * + * Efficient means the whole file is rewritten at most one time, and only + * when necessary. Level 1 is not efficient only in the case that you + * cause more than one metadata block to grow or shrink beyond what can + * be accomodated by padding. In this case you should probably use level + * 2, which allows you to edit all the metadata for a file in memory and + * write it out all at once. + * + * All levels know how to skip over and not disturb an ID3v2 tag at the + * front of the file. + * + * All levels access files via their filenames. In addition, level 2 + * has additional alternative read and write functions that take an I/O + * handle and callbacks, for situations where access by filename is not + * possible. + * + * In addition to the three interfaces, this module defines functions for + * creating and manipulating various metadata objects in memory. As we see + * from the Format module, FLAC metadata blocks in memory are very primitive + * structures for storing information in an efficient way. Reading + * information from the structures is easy but creating or modifying them + * directly is more complex. The metadata object routines here facilitate + * this by taking care of the consistency and memory management drudgery. + * + * Unless you will be using the level 1 or 2 interfaces to modify existing + * metadata however, you will not probably not need these. + * + * From a dependency standpoint, none of the encoders or decoders require + * the metadata module.

Some (like + * seeking) are optional, depending on the capabilities of the input. + * + * For decoding directly from a file, use FLAC__stream_decoder_init_FILE() + * or FLAC__stream_decoder_init_file(). Then you must only supply an open + * \c FILE* or filename and fewer callbacks; the decoder will handle + * the other callbacks internally. + * + * There are three similarly-named init functions for decoding from Ogg + * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the + * library has been built with Ogg support. + * + * Once the decoder is initialized, your program will call one of several + * functions to start the decoding process: + * + * - FLAC__stream_decoder_process_single() - Tells the decoder to process at + * most one metadata block or audio frame and return, calling either the + * metadata callback or write callback, respectively, once. If the decoder + * loses sync it will return with only the error callback being called. + * - FLAC__stream_decoder_process_until_end_of_metadata() - Tells the decoder + * to process the stream from the current location and stop upon reaching + * the first audio frame. The client will get one metadata, write, or error + * callback per metadata block, audio frame, or sync error, respectively. + * - FLAC__stream_decoder_process_until_end_of_stream() - Tells the decoder + * to process the stream from the current location until the read callback + * returns FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM or + * FLAC__STREAM_DECODER_READ_STATUS_ABORT. The client will get one metadata, + * write, or error callback per metadata block, audio frame, or sync error, + * respectively. + * + * When the decoder has finished decoding (normally or through an abort), + * the instance is finished by calling FLAC__stream_decoder_finish(), which + * ensures the decoder is in the correct state and frees memory. Then the + * instance may be deleted with FLAC__stream_decoder_delete() or initialized + * again to decode another stream. + * + * Seeking is exposed through the FLAC__stream_decoder_seek_absolute() method. + * At any point after the stream decoder has been initialized, the client can + * call this function to seek to an exact sample within the stream. + * Subsequently, the first time the write callback is called it will be + * passed a (possibly partial) block starting at that sample. + * + * If the client cannot seek via the callback interface provided, but still + * has another way of seeking, it can flush the decoder using + * FLAC__stream_decoder_flush() and start feeding data from the new position + * through the read callback. + * + * The stream decoder also provides MD5 signature checking. If this is + * turned on before initialization, FLAC__stream_decoder_finish() will + * report when the decoded MD5 signature does not match the one stored + * in the STREAMINFO block. MD5 checking is automatically turned off + * (until the next FLAC__stream_decoder_reset()) if there is no signature + * in the STREAMINFO block or when a seek is attempted. + * + * The FLAC__stream_decoder_set_metadata_*() functions deserve special + * attention. By default, the decoder only calls the metadata_callback for + * the STREAMINFO block. These functions allow you to tell the decoder + * explicitly which blocks to parse and return via the metadata_callback + * and/or which to skip. Use a FLAC__stream_decoder_set_metadata_respond_all(), + * FLAC__stream_decoder_set_metadata_ignore() ... or FLAC__stream_decoder_set_metadata_ignore_all(), + * FLAC__stream_decoder_set_metadata_respond() ... sequence to exactly specify + * which blocks to return. Remember that metadata blocks can potentially + * be big (for example, cover art) so filtering out the ones you don't + * use can reduce the memory requirements of the decoder. Also note the + * special forms FLAC__stream_decoder_set_metadata_respond_application(id) + * and FLAC__stream_decoder_set_metadata_ignore_application(id) for + * filtering APPLICATION blocks based on the application ID. + * + * STREAMINFO and SEEKTABLE blocks are always parsed and used internally, but + * they still can legally be filtered from the metadata_callback. + * + * \note + * The "set" functions may only be called when the decoder is in the + * state FLAC__STREAM_DECODER_UNINITIALIZED, i.e. after + * FLAC__stream_decoder_new() or FLAC__stream_decoder_finish(), but + * before FLAC__stream_decoder_init_*(). If this is the case they will + * return \c true, otherwise \c false. + * + * \note + * FLAC__stream_decoder_finish() resets all settings to the constructor + * defaults, including the callbacks. + * + * \{ + */ + + +/** State values for a FLAC__StreamDecoder + * + * The decoder's state can be obtained by calling FLAC__stream_decoder_get_state(). + */ +typedef enum { + + FLAC__STREAM_DECODER_SEARCH_FOR_METADATA = 0, + /**< The decoder is ready to search for metadata. */ + + FLAC__STREAM_DECODER_READ_METADATA, + /**< The decoder is ready to or is in the process of reading metadata. */ + + FLAC__STREAM_DECODER_SEARCH_FOR_FRAME_SYNC, + /**< The decoder is ready to or is in the process of searching for the + * frame sync code. + */ + + FLAC__STREAM_DECODER_READ_FRAME, + /**< The decoder is ready to or is in the process of reading a frame. */ + + FLAC__STREAM_DECODER_END_OF_STREAM, + /**< The decoder has reached the end of the stream. */ + + FLAC__STREAM_DECODER_OGG_ERROR, + /**< An error occurred in the underlying Ogg layer. */ + + FLAC__STREAM_DECODER_SEEK_ERROR, + /**< An error occurred while seeking.

At a minimum, the following + * functions should be called: + * - FLAC__stream_encoder_set_channels() + * - FLAC__stream_encoder_set_bits_per_sample() + * - FLAC__stream_encoder_set_sample_rate() + * - FLAC__stream_encoder_set_ogg_serial_number() (if encoding to Ogg FLAC) + * - FLAC__stream_encoder_set_total_samples_estimate() (if known) + * - If the application wants to control the compression level or set its own + * metadata, then the following should also be called: + * - FLAC__stream_encoder_set_compression_level() + * - FLAC__stream_encoder_set_verify() + * - FLAC__stream_encoder_set_metadata() + * - The rest of the set functions should only be called if the client needs + * exact control over how the audio is compressed; thorough understanding + * of the FLAC format is necessary to achieve good results. + * - The program initializes the instance to validate the settings and + * prepare for encoding using + * - FLAC__stream_encoder_init_stream() or FLAC__stream_encoder_init_FILE() + * or FLAC__stream_encoder_init_file() for native FLAC + * - FLAC__stream_encoder_init_ogg_stream() or FLAC__stream_encoder_init_ogg_FILE() + * or FLAC__stream_encoder_init_ogg_file() for Ogg FLAC + * - The program calls FLAC__stream_encoder_process() or + * FLAC__stream_encoder_process_interleaved() to encode data, which + * subsequently calls the callbacks when there is encoder data ready + * to be written. + * - The program finishes the encoding with FLAC__stream_encoder_finish(), + * which causes the encoder to encode any data still in its input pipe, + * update the metadata with the final encoding statistics if output + * seeking is possible, and finally reset the encoder to the + * uninitialized state. + * - The instance may be used again or deleted with + * FLAC__stream_encoder_delete(). + * + * In more detail, the stream encoder functions similarly to the + * \link flac_stream_decoder stream decoder \endlink, but has fewer + * callbacks and more options. Typically the client will create a new + * instance by calling FLAC__stream_encoder_new(), then set the necessary + * parameters with FLAC__stream_encoder_set_*(), and initialize it by + * calling one of the FLAC__stream_encoder_init_*() functions. + * + * Unlike the decoders, the stream encoder has many options that can + * affect the speed and compression ratio. When setting these parameters + * you should have some basic knowledge of the format (see the + * user-level documentation + * or the formal description). The + * FLAC__stream_encoder_set_*() functions themselves do not validate the + * values as many are interdependent. The FLAC__stream_encoder_init_*() + * functions will do this, so make sure to pay attention to the state + * returned by FLAC__stream_encoder_init_*() to make sure that it is + * FLAC__STREAM_ENCODER_INIT_STATUS_OK. Any parameters that are not set + * before FLAC__stream_encoder_init_*() will take on the defaults from + * the constructor. + * + * There are three initialization functions for native FLAC, one for + * setting up the encoder to encode FLAC data to the client via + * callbacks, and two for encoding directly to a file. + * + * For encoding via callbacks, use FLAC__stream_encoder_init_stream(). + * You must also supply a write callback which will be called anytime + * there is raw encoded data to write. If the client can seek the output + * it is best to also supply seek and tell callbacks, as this allows the + * encoder to go back after encoding is finished to write back + * information that was collected while encoding, like seek point offsets, + * frame sizes, etc. + * + * For encoding directly to a file, use FLAC__stream_encoder_init_FILE() + * or FLAC__stream_encoder_init_file(). Then you must only supply a + * filename or open \c FILE*; the encoder will handle all the callbacks + * internally. You may also supply a progress callback for periodic + * notification of the encoding progress. + * + * There are three similarly-named init functions for encoding to Ogg + * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the + * library has been built with Ogg support. + * + * The call to FLAC__stream_encoder_init_*() currently will also immediately + * call the write callback several times, once with the \c fLaC signature, + * and once for each encoded metadata block. Note that for Ogg FLAC + * encoding you will usually get at least twice the number of callbacks than + * with native FLAC, one for the Ogg page header and one for the page body. + * + * After initializing the instance, the client may feed audio data to the + * encoder in one of two ways: + * + * - Channel separate, through FLAC__stream_encoder_process() - The client + * will pass an array of pointers to buffers, one for each channel, to + * the encoder, each of the same length. The samples need not be + * block-aligned, but each channel should have the same number of samples. + * - Channel interleaved, through + * FLAC__stream_encoder_process_interleaved() - The client will pass a single + * pointer to data that is channel-interleaved (i.e. channel0_sample0, + * channel1_sample0, ... , channelN_sample0, channel0_sample1, ...). + * Again, the samples need not be block-aligned but they must be + * sample-aligned, i.e. the first value should be channel0_sample0 and + * the last value channelN_sampleM. + * + * Note that for either process call, each sample in the buffers should be a + * signed integer, right-justified to the resolution set by + * FLAC__stream_encoder_set_bits_per_sample(). For example, if the resolution + * is 16 bits per sample, the samples should all be in the range [-32768,32767]. + * + * When the client is finished encoding data, it calls + * FLAC__stream_encoder_finish(), which causes the encoder to encode any + * data still in its input pipe, and call the metadata callback with the + * final encoding statistics. Then the instance may be deleted with + * FLAC__stream_encoder_delete() or initialized again to encode another + * stream. + * + * For programs that write their own metadata, but that do not know the + * actual metadata until after encoding, it is advantageous to instruct + * the encoder to write a PADDING block of the correct size, so that + * instead of rewriting the whole stream after encoding, the program can + * just overwrite the PADDING block. If only the maximum size of the + * metadata is known, the program can write a slightly larger padding + * block, then split it after encoding. + * + * Make sure you understand how lengths are calculated. All FLAC metadata + * blocks have a 4 byte header which contains the type and length. This + * length does not include the 4 bytes of the header.

This is useful for scripts, and setting tags in situations where the locale is wrong. This option must appear before any tag options! +.TP +\fB-w, --warnings-as-errors \fR +Treat all warnings as errors (which cause flac to terminate with a non-zero exit code). +.TP +\fB-f, --force \fR +Force overwriting of output files. By default, flac warns that the output file already exists and continues to the next file. +.TP +\fB-o \fIfilename\fB, --output-name=\fIfilename\fB\fR +Force the output file name (usually flac just changes the extension). May only be used when encoding a single file. May not be used in conjunction with --output-prefix. +.TP +\fB--output-prefix=\fIstring\fB\fR +Prefix each output file name with the given string. This can be useful for encoding or decoding files to a different directory. Make sure if your string is a path name that it ends with a trailing `/' (slash). +.TP +\fB--delete-input-file \fR +Automatically delete the input file after a successful encode or decode. If there was an error (including a verify error) the input file is left intact. +.TP +\fB--keep-foreign-metadata \fR +If encoding, save WAVE or AIFF non-audio chunks in FLAC metadata. If decoding, restore any saved non-audio chunks from FLAC metadata when writing the decoded file. Foreign metadata cannot be transcoded, e.g. WAVE chunks saved in a FLAC file cannot be restored when decoding to AIFF. Input and output must be regular files (not stdin or stdout). +.TP +\fB--skip={\fI#\fB|\fImm:ss.ss\fB}\fR +Skip over the first number of samples of the input. This works for both encoding and decoding, but not testing. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second. +.TP +\fB--until={\fI#\fB|[\fI+\fB|\fI-\fB]\fImm:ss.ss\fB}\fR +Stop at the given sample number for each input file. This works for both encoding and decoding, but not testing. The given sample number is not included in the decoded output. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second. If a `+' (plus) sign is at the beginning, the --until point is relative to the --skip point. If a `-' (minus) sign is at the beginning, the --until point is relative to end of the audio. +.TP +\fB--ogg\fR +When encoding, generate Ogg FLAC output instead of native FLAC. Ogg FLAC streams are FLAC streams wrapped in an Ogg transport layer. The resulting file should have an '.oga' extension and will still be decodable by flac. + +When decoding, force the input to be treated as Ogg FLAC. This is useful when piping input from stdin or when the filename does not end in '.oga' or '.ogg'. +.TP +\fB--serial-number=\fI#\fB\fR +When used with --ogg, specifies the serial number to use for the first Ogg FLAC stream, which is then incremented for each additional stream. When encoding and no serial number is given, flac uses a random number for the first stream, then increments it for each additional stream. When decoding and no number is given, flac uses the serial number of the first page. +.SS "ANALYSIS OPTIONS" +.TP +\fB--residual-text \fR +Includes the residual signal in the analysis file. This will make the file very big, much larger than even the decoded file. +.TP +\fB--residual-gnuplot \fR +Generates a gnuplot file for every subframe; each file will contain the residual distribution of the subframe. This will create a lot of files. +.SS "DECODING OPTIONS" +.TP +\fB--cue=[\fI#.#\fB][-[\fI#.#\fB]]\fR +Set the beginning and ending cuepoints to decode. The optional first #.# is the track and index point at which decoding will start; the default is the beginning of the stream. The optional second #.# is the track and index point at which decoding will end; the default is the end of the stream. If the cuepoint does not exist, the closest one before it (for the start point) or after it (for the end point) will be used. If those don't exist, the start of the stream (for the start point) or end of the stream (for the end point) will be used. The cuepoints are merely translated into sample numbers then used as --skip and --until. A CD track can always be cued by, for example, --cue=9.1-10.1 for track 9, even if the CD has no 10th track. +.TP +\fB-F, --decode-through-errors \fR +By default flac stops decoding with an error and removes the partially decoded file if it encounters a bitstream error. With -F, errors are still printed but flac will continue decoding to completion. Note that errors may cause the decoded audio to be missing some samples or have silent sections. +.SS "ENCODING OPTIONS" +.TP +\fB-V, --verify\fR +Verify a correct encoding by decoding the output in parallel and comparing to the original +.TP +\fB--lax\fR +Allow encoder to generate non-Subset files. The resulting FLAC file may not be streamable or might have trouble being played in all players (especially hardware devices), so you should only use this option in combination with custom encoding options meant for archival. +.TP +\fB--replay-gain\fR +Calculate ReplayGain values and store them as FLAC tags, similar to vorbisgain. Title gains/peaks will be computed for each input file, and an album gain/peak will be computed for all files. All input files must have the same resolution, sample rate, and number of channels. Only mono and stereo files are allowed, and the sample rate must be one of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48 kHz. Also note that this option may leave a few extra bytes in a PADDING block as the exact size of the tags is not known until all files are processed. Note that this option cannot be used when encoding to standard output (stdout). +.TP +\fB--cuesheet=\fIfilename\fB\fR +Import the given cuesheet file and store it in a CUESHEET metadata block. This option may only be used when encoding a single file. A seekpoint will be added for each index point in the cuesheet to the SEEKTABLE unless --no-cued-seekpoints is specified. +.TP +\fB--picture={\fIFILENAME\fB|\fISPECIFICATION\fB}\fR +Import a picture and store it in a PICTURE metadata block. More than one --picture command can be specified. Either a filename for the picture file or a more complete specification form can be used. The SPECIFICATION is a string whose parts are separated by | (pipe) characters. Some parts may be left empty to invoke default values. FILENAME is just shorthand for "||||FILENAME". The format of SPECIFICATION is + +[TYPE]|[MIME-TYPE]|[DESCRIPTION]|[WIDTHxHEIGHTxDEPTH[/COLORS]]|FILE + +TYPE is optional; it is a number from one of: + +0: Other + +1: 32x32 pixels 'file icon' (PNG only) + +2: Other file icon + +3: Cover (front) + +4: Cover (back) + +5: Leaflet page + +6: Media (e.g. label side of CD) + +7: Lead artist/lead performer/soloist + +8: Artist/performer + +9: Conductor + +10: Band/Orchestra + +11: Composer + +12: Lyricist/text writer + +13: Recording Location + +14: During recording + +15: During performance + +16: Movie/video screen capture + +17: A bright coloured fish + +18: Illustration + +19: Band/artist logotype + +20: Publisher/Studio logotype + +The default is 3 (front cover). There may only be one picture each of type 1 and 2 in a file. + +MIME-TYPE is optional; if left blank, it will be detected from the file. For best compatibility with players, use pictures with MIME type image/jpeg or image/png. The MIME type can also be --> to mean that FILE is actually a URL to an image, though this use is discouraged. + +DESCRIPTION is optional; the default is an empty string. + +The next part specfies the resolution and color information. If the MIME-TYPE is image/jpeg, image/png, or image/gif, you can usually leave this empty and they can be detected from the file. Otherwise, you must specify the width in pixels, height in pixels, and color depth in bits-per-pixel. If the image has indexed colors you should also specify the number of colors used. When manually specified, it is not checked against the file for accuracy. + +FILE is the path to the picture file to be imported, or the URL if MIME type is --> + +For example, "|image/jpeg|||../cover.jpg" will embed the JPEG file at ../cover.jpg, defaulting to type 3 (front cover) and an empty description. The resolution and color info will be retrieved from the file itself. + +The specification "4|-->|CD|320x300x24/173|http://blah.blah/backcover.tiff" will embed the given URL, with type 4 (back cover), description "CD", and a manually specified resolution of 320x300, 24 bits-per-pixel, and 173 colors. The file at the URL will not be fetched; the URL itself is stored in the PICTURE metadata block. +.TP +\fB--sector-align\fR +Align encoding of multiple CD format files on sector boundaries. See the HTML documentation for more information. +.TP +\fB-S {\fI#\fB|\fIX\fB|\fI#x\fB|\fI#s\fB}, --seekpoint={\fI#\fB|\fIX\fB|\fI#x\fB|\fI#s\fB}\fR +Include a point or points in a SEEKTABLE. Using #, a seek point at that sample number is added. Using X, a placeholder point is added at the end of a the table. Using #x, # evenly spaced seek points will be added, the first being at sample 0. Using #s, a seekpoint will be added every # seconds (# does not have to be a whole number; it can be, for example, 9.5, meaning a seekpoint every 9.5 seconds). You may use many -S options; the resulting SEEKTABLE will be the unique-ified union of all such values. With no -S options, flac defaults to '-S 10s'. Use --no-seektable for no SEEKTABLE. Note: '-S #x' and '-S #s' will not work if the encoder can't determine the input size before starting. Note: if you use '-S #' and # is >= samples in the input, there will be either no seek point entered (if the input size is determinable before encoding starts) or a placeholder point (if input size is not determinable). +.TP +\fB-P \fI#\fB, --padding=\fI#\fB\fR +Tell the encoder to write a PADDING metadata block of the given length (in bytes) after the STREAMINFO block. This is useful if you plan to tag the file later with an APPLICATION block; instead of having to rewrite the entire file later just to insert your block, you can write directly over the PADDING block. Note that the total length of the PADDING block will be 4 bytes longer than the length given because of the 4 metadata block header bytes. You can force no PADDING block at all to be written with --no-padding. The encoder writes a PADDING block of 8192 bytes by default (or 65536 bytes if the input audio stream is more that 20 minutes long). +.TP +\fB-T \fIFIELD=VALUE\fB, --tag=\fIFIELD=VALUE\fB\fR +Add a FLAC tag. The comment must adhere to the Vorbis comment spec; i.e. the FIELD must contain only legal characters, terminated by an 'equals' sign. Make sure to quote the comment if necessary. This option may appear more than once to add several comments. NOTE: all tags will be added to all encoded files. +.TP +\fB--tag-from-file=\fIFIELD=FILENAME\fB\fR +Like --tag, except FILENAME is a file whose contents will be read verbatim to set the tag value. The contents will be converted to UTF-8 from the local charset. This can be used to store a cuesheet in a tag (e.g. --tag-from-file="CUESHEET=image.cue"). Do not try to store binary data in tag fields! Use APPLICATION blocks for that. +.TP +\fB-b \fI#\fB, --blocksize=\fI#\fB\fR +Specify the block size in samples. Subset streams must use one of 192, 576, 1152, 2304, 4608, 256, 512, 1024, 2048, 4096 (and 8192 or 16384 if the sample rate is >48kHz). +.TP +\fB-m, --mid-side\fR +Try mid-side coding for each frame (stereo input only) +.TP +\fB-M, --adaptive-mid-side\fR +Adaptive mid-side coding for all frames (stereo input only) +.TP +\fB-0\&..-8, --compression-level-0\&..--compression-level-8\fR +Fastest compression..highest compression (default is -5).

The exit code will be the only way to determine successful completion. + + + + + + + + Do not convert tags from local charset to UTF-8. This is useful for scripts, and setting tags in situations where the locale is wrong. This option must appear before any tag options! + + + + + , + + + Treat all warnings as errors (which cause flac to terminate with a non-zero exit code). + + + + + , + + + Force overwriting of output files. By default, flac warns that the output file already exists and continues to the next file. + + + + + filename, =filename + + Force the output file name (usually flac just changes the extension). May only be used when encoding a single file. May not be used in conjunction with --output-prefix. + + + + + =string + + Prefix each output file name with the given string. This can be useful for encoding or decoding files to a different directory. Make sure if your string is a path name that it ends with a trailing `/' (slash). + + + + + + + + Automatically delete the input file after a successful encode or decode. If there was an error (including a verify error) the input file is left intact. + + + + + + + + Output files have their timestamps/permissions set to match those of their inputs (this is default). Use --no-preserve-modtime to make output files have the current time and default permissions. + + + + + + + + If encoding, save WAVE, RF64, or AIFF non-audio chunks in FLAC metadata. If decoding, restore any saved non-audio chunks from FLAC metadata when writing the decoded file. Foreign metadata cannot be transcoded, e.g. WAVE chunks saved in a FLAC file cannot be restored when decoding to AIFF. Input and output must be regular files (not stdin or stdout). + + + + + ={#|mm:ss.ss} + + Skip over the first number of samples of the input. This works for both encoding and decoding, but not testing. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second. + + + + + ={#|[+|-]mm:ss.ss} + + Stop at the given sample number for each input file. This works for both encoding and decoding, but not testing. The given sample number is not included in the decoded output. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second. If a `+' (plus) sign is at the beginning, the --until point is relative to the --skip point. If a `-' (minus) sign is at the beginning, the --until point is relative to end of the audio. + + + + + + + + When encoding, generate Ogg FLAC output instead of native FLAC. Ogg FLAC streams are FLAC streams wrapped in an Ogg transport layer. The resulting file should have an '.oga' extension and will still be decodable by flac. + When decoding, force the input to be treated as Ogg FLAC. This is useful when piping input from stdin or when the filename does not end in '.oga' or '.ogg'. + + + + + =# + + + When used with --ogg, specifies the serial number to use for the first Ogg FLAC stream, which is then incremented for each additional stream. When encoding and no serial number is given, flac uses a random number for the first stream, then increments it for each additional stream. When decoding and no number is given, flac uses the serial number of the first page. + + + + + + + + Analysis Options + + + + + + + Includes the residual signal in the analysis file. This will make the file very big, much larger than even the decoded file. + + + + + + + + Generates a gnuplot file for every subframe; each file will contain the residual distribution of the subframe. This will create a lot of files. + + + + + + + + Decoding Options + + + + + + Set the beginning and ending cuepoints to decode. The optional first #.# is the track and index point at which decoding will start; the default is the beginning of the stream. The optional second #.# is the track and index point at which decoding will end; the default is the end of the stream. If the cuepoint does not exist, the closest one before it (for the start point) or after it (for the end point) will be used. If those don't exist, the start of the stream (for the start point) or end of the stream (for the end point) will be used. The cuepoints are merely translated into sample numbers then used as --skip and --until. A CD track can always be cued by, for example, --cue=9.1-10.1 for track 9, even if the CD has no 10th track. + + + + + , + + + By default flac stops decoding with an error and removes the partially decoded file if it encounters a bitstream error. With -F, errors are still printed but flac will continue decoding to completion. Note that errors may cause the decoded audio to be missing some samples or have silent sections. + + + + + + + + Encoding Options + + + + , + + + Verify a correct encoding by decoding the output in parallel and comparing to the original + + + + + + + + Allow encoder to generate non-Subset files.

Title gains/peaks will be computed for each input file, and an album gain/peak will be computed for all files. All input files must have the same resolution, sample rate, and number of channels. Only mono and stereo files are allowed, and the sample rate must be one of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48 kHz. Also note that this option may leave a few extra bytes in a PADDING block as the exact size of the tags is not known until all files are processed. Note that this option cannot be used when encoding to standard output (stdout). + + + + + =filename + + + Import the given cuesheet file and store it in a CUESHEET metadata block. This option may only be used when encoding a single file. A seekpoint will be added for each index point in the cuesheet to the SEEKTABLE unless --no-cued-seekpoints is specified. + + + + + ={FILENAME|SPECIFICATION} + + + Import a picture and store it in a PICTURE metadata block. More than one --picture command can be specified. Either a filename for the picture file or a more complete specification form can be used. The SPECIFICATION is a string whose parts are separated by | (pipe) characters. Some parts may be left empty to invoke default values. FILENAME is just shorthand for "||||FILENAME".
