I usually go for this kind of command:

	cmp whatever.iso /dev/sr0

If it reports "EOF on whatever.iso" its fine :)

This method does not, however, check the speed or any soft errors that the  
firmware and driver were able to correct. You could run a `dmesg -w` in  
parallel to find out about them in a qualitative way (if there are many  
"buffer IO errors" the burn quality could be bad?).

Can you mount it and view the individual tracks as files?
Did you supply the .wav files exactly as they were going to be burnt unto  
the disc?

If both is yes, might it make sense to compare the individual track files  
against your supplied sources?

I have not tried to verify audio discs this way, though.
