Is it possible, through Unix, to extract a sample from
a music CD-ROM?

We have a program that plays CD's on our Unix CD-ROM
drive.  It uses SCSI ioctl calls to send commands.
My guess is that the best bet would be to send some 
sort of ioctl to the drive asking it to return a certain
block or sector on the CD-ROM.  Possible?

Then, what kind of format is the data in?  How hard would
it then be to convert it into AIFF/uLAW or some other 
well know format?

This would be very useful information for me, and I 
would think, a wide number of others.  Any hints are 
appreciated.
