Description

When converting a CDDA to CDRWin's BIN+CUE format, I've noticed that Track 1 often starts abruptly, not how I remember the CD starting. The generated Cue sheet reports the audio starting at 2 seconds, which is about 1.5 seconds after the audio actually seems to start.

However it's clear the the audio is starting earlier than 00:02:00 by opening the raw file in audacity.

If I'm using aaru wrong, that's fine, I haven't made a lot of progress, but I'd like to learn that now than later. Is this related to my drive not being in the drive database?

Edit: I get the same issue when I providing the --first-pregap option to aaru media dump.

The problem is that in 472a1d94d8/Aaru.Core/Devices/Dumping/CompactDisc/Dump.cs (L1047) it is not finding your drive in the database.

I ran aaru database update --clear-all and I see that section now reports a drive offset:

Drive reading offset is 2668 bytes (667 samples).
Disc write offset is unknown, dump may not be correct.
Setting speed to MAX for data reading.
Setting speed to 8x for audio reading.
Setting index 1 for track 1 to LBA 0.

However the Cue sheet still reports 00:02:00 as the beginning of track 1, and the audio still starts before this point in the BIN file when viewed in Audacity.

nothing to do with the problem.

However the Cue sheet still reports 00:02:00 as the beginning of track 1, and the audio still starts before this point in the BIN file when viewed in Audacity.

Seems there is a problem with cue generation.

The earliest the index 1 of track 1 can start is 00:02:00 (LBA 0), however CDRWin Cuesheet considers 00:00:00 as the start of the file (this is LBA 0).

So what really, in the disc is:

INDEX 00 00:00:00
INDEX 01 00:02:00

in the cuesheet should be:

INDEX 01 00:00:00

The bug is therefore in this method:

@terinjokes commented on GitHub (Feb 2, 2021):

The INDEX 00 gets added here, when the track has a pregap.

16e043cedd/Aaru.Images/CDRWin/Write.cs (L520-L529)

150 frames (as we can see in aaru image info) is 2 seconds (assuming 75 frames/second), which is the area for the TOC. So this seems accurate, however, per a user on the hydrogenaudio forums:

INDEX 00 implies that the pregap is included in the rip. PREGAP implies that it is digital silence and not included in the rip. The result produces the same disc if the pregap is indeed digital silence.

It seems like the correct behavior might be to change this to a PREGAP if aaru doesn't include that audio in the data? Or change the condition to only add the INDEX 00 if the pregap is longer than 150? I'll be hesitant to make such a change without understanding what aaru does for gaps between tracks.

Sorry, if I'm barking up the wrong tree.

For sake of comparison, I also ripped with cdrdao to see what it was doing.

The raw file looks the same however, so I agree the Cue sheet generation is the likely culprit here.

150 frames (as we can see in aaru image info) is 2 seconds (assuming 75 frames/second), which is the area for the TOC.
It's not, 150 sectors is the minimum size for the first track of a session.

The solution for the bug is to not write an index 00 for track 1, and displace the LBA to MSF 150 sectors.

On discs, LBA 0 == MSF 00:02:00, LBA -150 = MSF 00:00:00.
On cuesheet, LBA 0 == MSF 00:00:00, it doesn't store negative LBAs.

This is not the solution because INDEX 00 for track 1 is where HTOA is represented.

Sorry, what do you mean with HTOA?

I have not been able to get CDRWin or IsoBuster to properly dump any disc with a hidden track, tried with a CD-i Ready and an audio one.

@FakeShemp you had one, can you try and see what CDRWin 3/4 generates for INDEX 0, if any?

@claunia commented on GitHub (Feb 3, 2021):

Ok so correct behaviour is to put INDEX 00 in the CUE when the pregap is bigger than 150 sectors and INDEX 01 with 2 seconds less.

So:
Track 1 index 0 => 00:00:00 (LBA -150)
Track 1 Index 1 => 02:35:15 (LBA 6992)

If(track1.Pregap > 150)

Cue:

INDEX 00 00:00:00
INDEX 01 02:33:15

While:
Track 1 index 0 => 00:00:00 (LBA -150)
Track 1 index 1 => 00:02:00 (LBA 0)

If(track1.Pregap <= 150)

Cue:

INDEX 01 00:00:00

That solves the hidden tracks case.
