Real-time computer modeling of woodwind instruments

Abstract

This paper presents a digital waveguide woodwind instrument tonehole implementation which, in a single model, characterizes all states of the hole from open to closed. This efficient implementation produces results which agree well with previous acoustical analyses of the tonehole. A similar model is also presented for the register hole. A complete woodwind instrument model with many toneholes and register hole(s) is implemented in a cross-platform, C++ real-time computer programming environment. A new wind controller created to control the woodwind model is also briefly discussed.
