<li>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.</li>

<li>Improved the <span class="argument"><a href="documentation.html#flac_options_decode_through_errors">-F</a></span> option to allow decoding of FLAC files whose metadata is corrupted, and other kinds of severe corruption.</li>
<li>Encoder can now take FLAC as input. The output FLAC file will have all the same metadata as the original unless overridden with options on the command line.</li>
<li>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.</li>
<li>Encoder can now take WAVEFORMATEXTENSIBLE WAVE files as input; decoder will output WAVEFORMATEXTENSIBLE WAVE files when necessary to conform to the latest Microsoft specifications.</li>
<li>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.</li>
<li>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.</li>

<span class="commandname">flac</span> is the command-line file encoder/decoder. The encoder currently supports as input RIFF WAVE, AIFF, or FLAC format, or raw interleaved samples. The decoder currently can output to RIFF WAVE or AIFF format, or raw interleaved samples. <span class="commandname">flac</span> 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.

<span class="commandname">flac</span> assumes that files ending in ".wav" or that have the RIFF WAVE header present are WAVE 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 ".ogg" are Ogg FLAC files. Other than this, <span class="commandname">flac</span> makes no assumptions about file extensions, though the convention is that FLAC files have the extension ".flac" (or ".fla" on ancient file systems like FAT-16).

Before going into the full command-line description, a few other things help to sort it out: 1) <span class="commandname">flac</span> encodes by default, so you must use <b>-d</b> to decode; 2) the options <span class="argument">-0</span> .. <span class="argument">-8</span> (or <span class="argument">--fast</span> and <span class="argument">--best</span>) 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) <span class="commandname">flac</span> behaves similarly to gzip in the way it handles input and output files.

In test mode, <span class="commandname">flac</span> 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.
<br /><br />
<span class="commandname">flac</span> can also re-encode FLAC files. In other words, you can specify a 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.).
