	This document contains information relevant to the AV Macs, 
especially in relation to the use and programming of their DSP chip.  It 
is the product of my own experience and many helpful responses I 
have received to posts I have made.  I have taken slight liberties in 
editing responses, so what you see below are not always the exact words 
of the contributors to the FAQ.  It is structured in the typical FAQ 
format of question and answer with the questions listed at the 
beginning.  Please write me with any additions to or comments about this 
document.

1. Are modem/fax software and the GeoPort telecom adapter included?
2. Does audio output from the CD have an extra stage of A/D & D/A?
3. Is there an included utility which allows digital recording of part 
of an audio CD to an AIFF file?
4. Is there an included utility which will allow me to play/record 16-
bit, 44.1KHz stereo AIFF files?
5. Is there any digital audio software available for the 660AV?
6. Is there any digital audio interfacing hardware available? (AES/EBU 
<--> DAV  or  AES/EBU <--> GeoPort)
7. What is needed to do DSP programming?
8. Where can I get example code for programs that use the AV's DSP?
9. Where can I get information about the DSP chip?
10. BugLite only supports 32-bit floating point data.  Do I really want 
to use this data type?
11. Can I use Think C to write the Macintosh part of DSP applications?
12. What happens to DSP modules I have written when the hardware 
platform changes (to PowerPC, for instance)?



.c.1. Are modem/fax software and the GeoPort telecom adapter included? 

	The Geoport adapter must be bought separately for about $125. The 
adapter comes with the modem driver software and a complete, user-level 
fax software package.  So you still need to own a separate modem 
communications program.  Contrary to what some documentation says, you 
can do 14.4Kbaud, not just 9600 baud, with the modem.
	As an aside, I would like to point out that though the AV does 
speech generation and recognition right out of the box, it can't do 
modem/fax out of the box.  Frankly I cannot believe that the number of 
users needing speech functions even approaches the number who need 
modem/fax.  A clear case of "Gee-whiz! Bells & whistles! Screw the
