Or, you could (presumably) just suck blocks of audio data off of the disk and
get your sound as raw bits. I imagine the DACs on your average CDROM drive
are pretty crap to say the least, so you'll get a way better copy if you do it
raw. IIRC, the CD audio and data formats are practically identical so doing
this should be simple(ish).
Cheers,
Scott
