I have a few questions relating to digital audio and standard
audio casettes.

1) Does anybody know how to read raw audio data from a CD in a
   CD-ROM player on a rs6000 or a dec3100 so that the audio
   waveform(s) can be analyzed?
2) What are the current schemes being thought of for audio
   data compression?  I've heard about using a displacement from
   the previous value pretty recently.  I'm talking about NOT
   compromizing a 16bit digital signal in any way, as the
   mini-CD format does do, I believe.
3) What is the bandwidth (per square inch/cm) of standard
   audio tape?  (or would it be cross section in inches??)

Thanks,
Doug Puchalski
