Digital Simulation of Musical Instrument String Based on Physical Model
Shuli Zheng · Acta Simulata Systematica Sinica · 2003
Simulation of musical instrument based on physical model is a kind of method that is able to describe accurately sound of instrument by the theory of elasticity and PDE. Nowadays, the method is becoming an important research domain of instruments simulation with improvement of computers processing power. This paper depicts a simple numerical model of musical instrument string based on physical model, and then, derives a new kind of great facility algorithm with ordinary explicit expression to process on computer. Compared with L.R Second-order Recursive System, it has been proved that the arithmetic is not only simpler, but also more accurate. It is valuable to use as reference for researchers developing simulation of musical instrument and sound synthesis.
