I guess from your use of wodim, that you deal with genisoimage
out of cdrkit, the Debian fork of cdrtools as of 2006.
Its homepage seems to have gone meanwhile, but there are
source tarballs like
  http://ftp.de.debian.org/debian/pool/main/c/cdrkit/cdrkit_1.1.11.orig.tar.gz  
and in there
  drwxr-xr-x steve/users       0 2010-10-18 00:29:38 cdrkit-1.1.11/genisoimage/

It is unlikely that the code for option -C has changed
significantly since cdrkit was forked. So the exact version
should not matter much.

I myself mostly refrain from looking into this source, because
i want to keep my code independent of cdrtools. A few times i
had to do, nevertheless, to identify bugs or the reason of
peculiar behavior.

Thanks for the template. I already began to get lost in the man
page. :)

man cdrdao states that you can fill in the raw random data:
"[ FILE | AUDIOFILE ] "<filename>" <start> [ <length> ]
 ...
 Audio files may have raw or WAVE format with 16 bits per sample,"

Actually the CD wants raw data, aligned to blocks of 2352 bytes.
The following URL helped me to teach libburn reading raw data
from a .wav file:

But maybe there is a patent about automatic generation of
GEMA-free music. 8-O


Have a nice day :)
