Although my experience with Mac CD-ROM is limited, I agree with the other
folks here that you cannot (from the CD-ROM interface) get access to Red
(CD-DA) Sectors.  I know that this is the case even with CD-I, which in general
is much more open than CD-ROM.

But it is possible to get that data.  We have a high-end CD-DA player with
Digital Outputs.  We connect this digital out to a VME system with a digital
audio capture card.  From there, we can pipe the PCM data back out and into
a system like the DigiDesign "SoundTools", or simply transfer it via Ethernet
to our favorite system for editing and further encoding to ADPCM.

If you have other specific questions you can contact me directly.
