A simplified source/filter model for percussive sounds

Abstract

This paper deals with source-filter models of percussive instruments. A 'multi-channel excitation/filter model' is presented in which a single excitation is used to generate several sounds, for example six piano tones belonging to the same octave. Techniques for estimating the model parameters are presented and applied to the sound of a real piano. Our experiments demonstrate that it is possible to calculate a single excitation signal which when fed into different filters, generates very accurate synthetic tones. Finally, a low-cost synthesis method is proposed that can be used to generate natural sounding percussive tones.<>
