By the way, who has written the piano.scm file or piano.ins? "Scott Van Duyne" model is written there. He has written the program, too? I ask myself how to get to the "table" numbers and what each number means:
:detuningFactor-table '(24 5 36 7.0 48 7.5 60 12.0 72 20 84 30 96 100 108 300) :stiffnessFactor-table '(21 1.5 24 1.5 36 1.5 48 1.5 60 1.4 72 1.3 84 1.2 96 1.0 108 1.0) Is it possible (as far as you know) to get such factors from real instruments or are they more artificial and a bit far away from "real physics"? I have a classical guitar model written in MATLAB where I put in the string length, density, Youngs Modulus etc. and the output is a tone in .wav. There I have a direct connection from physical changes (plucking place etc.) to physics. But if I look at the piano model I see such tables and factors... but the commuted piano model on which it is based is called a "physical model". When is a model called "physical"? If it's based on the wave equation somewhere? I like to create tones (guitar: plucked at random places (e.g. normal distributed), piano (vary some parameters) etc.) to get many tones with which I can do my classification and later to consider the instrument recognition from short pieces of music. That's why I am looking for physical models, because there are parameters that can be varied. There are good physical models (-> pianoteq), but the question is: how god has a model to be that it's good enough for classification later... Perhaps I will try it first with this model and if it's too bad for it, I have to go on searching... or to use pianoteq. Or do you know other piano-models (saxophone also sounds a bit strange in comparison to real saxophones)? _______________________________________________ Cmdist mailing list [email protected] http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist
