I think this is similar to that recipe from the debianforum, only that
the latter seems to be a little more refined. I guess I could wrap those
three commands in a little script, so I can do something like:
$ check-disc whatever.iso
Checksums match, thumbs up
resp.
$ check-disc whatever.iso
Checksums mismatch, thumbs down

I don't think audio-CDs can be mounted.

The problem here might be that if the original .wav files' duration did
not match that 2352 bytes sector size (or whatever this is called :) of
the CDDA format and thus had to be padded with zeroes there will be a
difference even though the actual PCM data may be perfectly the same. Or
at least that is as I understand it :)
Thanks for the feedback, and best regards
