[PD] Looking for research in amplitude envelopes of music instruments during performance.

Hi Rich,

Maybe you can consider taking another approach - not about the envelopes 
but how the sound is made.
Working from an algorhitm based on the physics of the instrument and the 
player and listen (with your ears) how musicians use things as 
embouchure, trills & frills and dynamics. Like said by Ingo - there is 
no one way to it. To take brass instruments as an example; a jazz 
musician will probably play different than a Bulgarian folk musician or 
a Baroque musician. Different styles of music ask for different styles 
of playing and thus envelopes.

Cheers, Wilfred
