Abstract:

This paper presents a discrete-time model for simulation of woodwind toneholes in a musical sound synthesis context. Starting from a lumped element approximation of the partially open tonehole, we develop an efficient digital tonehole model with dynamically adjustable tonehole state. The model, that covers a wider range of woodwind toneholes than those previously reported, is discretised with the use of wave digital filter techniques.
