[Gwc-general] Invalid cdrdao toc file

[Brian B. <br...@pi...>]

I am using GWC 0.21-16, which is currently shipped with the ubuntu 
studio 12.04 precise pangolin beta 2. It is also the current version 
with my production ubuntu studio 11.10 system.

It isn't strictly relevant, but I convert vinyl to digital using an 
Edirol FA-66 firewire device controlled by jackd and captured by Ardour.

I use Ardour to export a single wav file for the entire vinyl album and 
then use gwc to clean up the recording.

When I have a wav file that I like, I then manually mark the boundary of 
each track with "Markers -> Add Song Marker". Finally, I "View -> 
SelectAll" and then "File -> Create cdrdao toc file As...".

I manually fill in the album and track names on the toc dialogue and 
save the file. I write a new CD with "cdrdao --speed 4 export.toc". This 
is a procedure I've been following for several years without any problems.

However, since I upgraded gwc to 0.21-16, cdrdao has complained about 
the toc files and refused to write the cd as follows:

brian@schizo:~/WeatherReport-sportinLife/export$ cdrdao write --speed 4 
export.toc
Cdrdao version 1.2.3 - (C) Andreas Mueller <an...@da...>
ERROR: Track 7: Requested length (89737555 + 12992447 samples) exceeds 
length of audio file 
"/home/brian/WeatherReport-sportinLife/export/export.wav" (102729733 
samples at offset 0).
ERROR: The toc check function detected at least one warning.
ERROR: If you record this toc the resulting CD might be unusable
ERROR: or the recording process might abort with error.
ERROR: Use option --force to ignore the warnings.
ERROR: Toc file "export.toc" is inconsistent.

The toc file is fairly badly wrong - the first track does not even start 
with sample number zero!

I took a copy of the bad toc file and manually edited all the track 
start and length sample counters. I took the actual boundaries by 
displaying the sample counters for each of the song markers displayed by 
gwc, so we were working off the same wav file and analysis. My manual 
sample counters were very different to those automatically generated by gwc.

I've googled, but not found anything relevant. Am I using the 
appropriate dialogue to create my toc file on this release of gwc (i.e. 
this is a user error), or does this sound like a bug? (I notice you've 
added new toc file features in recent releases, so perhaps this is 
collateral damage.)

I don't know whether your mailing list strips attachments, so I won't 
send the two files at this time. I'm happy to send them in-line if 
anyone feels they would help in diagnosis.

Obviously this isn't urgent for me because I have a tedious but viable 
bypass for the problem. However, this version of gwc is being pushed out 
as 0.21.16~dfsg-3build (precise) and 0.21.16~dfsg-3 (oneiric) from the 
ubuntu repositories, so it has a wide exposure!
