i hope you don't mean that it would have to be stored in RAM...
first of all, many sets couldn't fit on a CD. but let's say you had a 75
minute set:
75 min X 60 sec/min X 44.1 ksamples/sec X 32 bits/sample X 2 channels
= 12,700,800,000 bits
= 1,587,600,000 bytes
1.6 Gig is a lot of memory. even if you could accomplish 10:1 compression,
you'd still need 160 Meg.

| Nominal CD data is 44.1 ksamples/sec x 16 bits/sample, not 32 (although
some CD audio mastering systems apparently digitise at 18 or 20
bits/sample and filter down to 16).
CD mastering subsystems for PCs often include a hard disk large enough
to hold a CD's worth. You write out to the disk and edit that until you
have it right and then tell it to transfer to the CD-R. Once advantage
of this scheme is that you can usually tell the hard disk to behave
like a single or double speed CD-ROM drive so you can test drive the app
(not so important for raw data, critical for multimedia).
There are also straight CD-R drives, but I don't know if they are
capable of writing CD-DA (audio) format.
Compression is of course not an option if you want these things to be
playable on an audio CD player.

I saw some Italian-import bootleg Phish CDs last weekend in a CD-swap-shop...
single live CD - $30. double live CD - $60.
And my second thought (after "HOLY SH*T, I'd be rich if I didn't have any
sense of ethics!") was that I already have both shows on DAT :-)
BTW, the Phish live CD comes out on June 27th -- so says the latest Doniac
Schvice.
