Anyone can tell me how to implement in pd a digital waveguide model for i.e. a string or a tube?

I'm not sure to understand, but ifthe question is to have a sound synthesis like a string or a tube, you have to check the percolate library. It is just what you want.

Sorry, I was not clear enough... What I want to implement is a digital waveguide model of a human vocal tract, which is like a tube with a variable section along x axis. But the first step is to do it for a constant section tube.

well the first step in implementing something like this in pd is to understand the principles behind waveguide synthesis. this is an area i am not particularly familiar with; though it does sound intersting. do you have any information on any existing research done in this area? if you know how people have handled it without Pd, you're a step closer to being able to implement it with Pd.

from the little i know about waveguides, i think that part of the process somehow involves delay lines (i could be wrong here, i am just trying to remember something a read a couple years back in computer music journal).

giair's idea with percolate is the closest thing i can think of too, as far as physical modelling goes....

maybe do a google for "pd percolate" and you'll find them.


however, human vocal chords do look VERY complicated!
