Allow me to comment briefly on the FAQ about DSP effects.  I'll forward a copy
to Phil for the official FAQ if appropriate.

Sample Mot DSP56001 code for stereo reverb, chorus, and flange is included
with my freeware assembler for the 56001.  V1.1 was recently posted to
alt.sources and may be found (for the moment) via anonymous ftp on
newsun.novell.com /pub/a56v.1.1.tar.Z.  My reverb code, as well as another
implementation can be found on Dr. Bubb.

Attached are some additional postings with references, etc.

William Alves posted this recently, how did you *all* missed it?

Check more articles from Journal of the Audio Engineering Society
(JAES), for example more articles by Strawn.

Start with "Elements of Computer Music" by Richard Moore....
Order it to your library if not exists!

I just received _Digital Audio Signal Processing_ yesterday.  I have
been consuming it voraciously.  I thank Bill Alves and Juhana Kouhia
for the pointers.

I also have ordered _Elements of Computer Music_ from Prentice Hall
and am anxiously awaiting its arrival as well.  Here is some ordering
information for those who might be interested.

Subject: Re: The Computer Music and Digital Audio Series

Contents of _Digital Audio Signal Processing, An Anthology_:

    1. Introduction to the mathematics of DSP (F. Richard Moore)
       (Not a bad little text)

    2. Introduction to digital filter theory (Julius O. Smith)
       (Not a bad little text, either)

    3. Spiral Synthesis (Tracy Lind Petersen)
       (first published account of a new synthesis technique)

    4. Signal processing aspects of computer music (J. A. Moorer)
       (James Moorer's classic article--discusses many synthesis
       techniques.  Reverb algorithms.  More than 6 pages of refs)

    5. An introduction to the phase vocoder (J. W. Gordon, J. Strawn)
       (Includes source code for a phase vocoder--a powerful method
       for synthesis, pitch shifting, time scale modification, etc)


And from the dust jacket-

The articles in this book were written for both the beginner and the advanced
practitioner of digital signal processing, especially as it relates to digital
audio.  Digital signal processing gives insight into matters such as
digitization and sampling, inherent in the creation of digital audio.
Musically useful tools fot the manipulation of sound, such as filtering,
reverberation, spectral analysis, and cross-synthesis, are anchored in
digital signal processing as well.
