Linked to my article asking for info. on Chas. Taylor, I would like to
ask whether anyone has the CD mentioned above. I am trying to track down
an acoustic illusion used by Prof. Taylor in the course of a lecture in
London... Is there such a track on that CD  ---  of a musical tone which
seemingly descends infinitely in pitch?

I would be glad to here of anyone who has the CD!

Hi Martyn, et al.,

I have the ASA's Auditory Demonstration CD and I must say that it's great!
I believe that the answer to your question is yes, it does contain
a demonstration of Shepard's Scale (an M.C. Escher painting for the ear).
I've also made a QuickTime movie of Shepard's Scale based upon a 
delightful book (w/CD-ROM) _Exploring_Mathematics_with_Mathematica_
by Theodore W. Gray and Jerry Glynn, Addison-Wesley, 1991; someday I'll
unleash on the net.  Also of interest is Malcolm Slaney's HyperCard stack
that complements the ASA CD; it's available via anonymous ftp from
ftp.apple.com.  (The ASA CD may be ordered directly from the ASA, see
the last few pages of a JASA for details.)

Joe (you've tempted me, please send me your chocolate ice-cream recipe)
