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

The big difference is how humans and machines are making the choices.
Machines can create any frequency and combine all kind of frequencies in
millions of ways. Does that make it music?

BTW, you shouldn't limit envelopes to volume.
Sound, frequencies, purity (like noise vs. defined frequencies), things like
vibrato envelopes, changes in the noise amount and type, etc. have envelopes
on every note or the structure of parts or the entire piece of music.

Looking at waveform envelopes describes just a small percentage of what you
can actually hear in a single note of music.

pretty sure machines can create a close to endless amount of envelopes too. 
It's just that nobody has taken enough care to start programming them that

Hi Rich.

Bill Schottstaedt set up a wonderful hands-on about extracting envelopes
(amp, pitch) from recordings of birdsongs, getting great results in the


I've used the same approach on recordings of more complex natural
environments, but the method would be useful for recordings of notes or
phrases played on musical instruments.
