Modeling and modification of violin body modes for sound synthesis

This paper discusses a new technique for obtaining efficient computational models of violins that are classified as being of different quality. The motivation of the work is the desire for parametric adjustment of the transfer characteristics of the violin body changing the instrument quality, and giving realistic and efficient body resonance models by signal processing methods. Model-based signal processing methods for estimating the model parameters and implementing an efficient violin body model for use with physical modeling synthesis is described. The main approach is to extract the lowest modes of the violin body for fully parametrized implementation of these resonances using digital filtering. The advantage of this approach is the capability of adjusting the parameters of body modes, such as the resonance frequencies affecting the sound quality in the violin sound synthesis.
