William Gaver discusses techniques for creating auditory icons in a paper 
presented at ICAD '92.  Iwas wondering if anyone on this list knows of 
anyone that may have used csound to create these icons or sounds based on 
his ideas.
	Basically, he describes in his paper several algorithms for 
creating sounds of objects either impacting each other, bouncing off each 
other, or scraping against each other.  The way these algorithms were 
designed the listener could asertain the materiel each substance was made 
of just by listening to the synthesized sound.  

Any information on this subject would be greatly apreciated,

Thanx,  John Beahan
