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

[Rich Eakin]

Hi all,

This topic isn't about pd per-say, but I bet there are many on this list
that know about it, so it was the best place I could think of to ask.

Is anyone aware of studies, articles, or other research that has been
conducted around the amplitude envelopes of real world music instruments
(strings, brass, voice, etc) during performance? What I mean is, I've seen
a few articles here and there that explain how the envelopes differ between
musical instruments (such as figure 5 of this article
<http://interscience.in/IJCSI_Vol2Iss1/IJCSI_Paper_4.pdf>), but the source
analysis samples are too simple for musical usefulness, usually a single
note recorded with basic dynamics.  What I'd like to find is more how the
ADSR curves look for actual musical phrases.

The end result would be applied to a composition tool I'm working on that
provides control over the envelopes of the notes. Right now I'm going with
the standard exponential attack/decay/release, as found in analog synths,
but I've always wondered what these curves look like in acoustic
instruments and real world situations..

Or perhaps if there is a better place to ask that someone can think of, I'd
be happy to post my question there. Its not easy for find recordings to do
the analysis and it would be quite time consuming to produce anything
reliable, but I figure there's gotta be people out there that have done
immense work in this topic.

cheers,
Rich
