[sdiy] Auditory Illusions

[Tom Arnold]

So, to answer my own question and pass on the info I found cause its kinda
cool and at least a couple of these illusions can definatly be deployed in
hardware, I'm just wondering if to usefull effect or not.

A handfull of effects.  Not sure how long this site will remain, its looking 
pretty broken.  I may ask for permission to mirror it.  Put on some 
headphones...

The research of Diana Deutsch who has written a multitude of papers on
Auditory Illusions.  More info then you can shake a stick at.

Some of these sound cool and some dont but are interesting anyway.  The
problem with most illusions it seems is that when you hear them you think
you hear one thing when you really are just hearing another, which isnt the
effect I want, some of the timing.  Besides the Shepard effect, the next
coolest one I found was 
http://www.unl.edu./secd/psychoa/experiments/preceden.html
Which might be hard to do with midi devices because the timing differences
are very tiny, but I'm thinking I can implement it to effect in my 32 step
sequencer as its basically a pair of Superseques in a box that can be
chained or paralleled, an LFO driving a tiny tiny delay between the two
sequencers might just do it.  Actually, if I seperate the gate signal and
just delay one a little, that might be even better.  At least some fun ideas
to play with.
