Musical Instrument Simulation Based on Physical Model
Wenjuan Cheng · Acta Simulata Systematica Sinica · 2003
Musical simulation technique based on physical model is a theory that is able to describe the characteristic ofobject抯 vibration by partial differential equation. It can not only simulate accurately musical instrument抯 sounds and itssounding process, but also reflect the player抯 controlling force strength and speed and emotion. Its playing methods and controlling parameters are the same as those of real musical instrument, unlike artificial synthesis sounds. With improvement of the computational power of computer, and MPEG4 technique being published, physical model methods is becoming one of the most important research domain about musical instrument simulation and sound synthesis. At first, this paper depicts five methods mostly used over physical model, analyzes their characteristics and defects, and explains the fundamental ideals and algorithms. And then, limitations of the two most famous physical models are discussed here. So, we propose a new one-dimensional and two-dimensional model according to their respective limitation.
