[Csnd] the "shimmer/sheen" of a violin

	I'm doing some experiments with pvs analysis of instruments and reducing them to gen10 tables which I play back with oscili. For instance, a violin. I realize there is much inharmonic energy in the violin. In particular, I'm interested in the beautiful sheen/shimmer in the high harmonics. This disappears when I play it back with a purely harmonic spectrum.. there is still high-frequency energy there, but sounds like a power drill. So what I'd like to know is, is there a simple model that produces the shimmer? It doesn't have to be an exact physical model; I'm wondering if there is something simple that imitates it. Maybe granular synthesis? Dennis

	Well... despite being a criminal enterprise, you might want to have a look at the SHARC timbre database by Greg Sandell: http://www.timbre.ws/sharc/ And, incriminating though this may be: Stephen Yi made a Csound version of the SHARC database on his Csounds.com page: http://csounds.com/stevenyi/ But... don't get caught.
