Why would you want to?  Using CD Audio frees the processor up for other 
tasks while producing excellent-quality sound (music, whatever).

As far as I know, it is _illegal_ to read the data on audio cd's.  Why?  
Well, you'd be able (if you had a CD Burner) to make exact duplicates of 
Audio CD's, which is an infringement of Copyright law.

Your best bet is just to play the CD Audio using standard techniques, and 
not worry about the .wav conversion.  Your programs will run faster (as 
the CPU doesn't have to worry about the digital audio), and your software 
will be legal!

Just out of curiosity, though, why do you need to do this?
