Digital modeling of string instrument bridge reflectance and body radiativity for sound synthesis by digital waveguides
Comunicaci贸 presentada a: 2015 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA 2015), celebrat a New Paltz, Estats Units, del 18 al 21 d'octubre de 2015.This paper proposes a method for modeling bridge reflectances and body radiativity profiles as digital filters in the context of sound synthesis by digital waveguides. The model is based on modal analysis of bridge driving-point admittance measurements obtained experimentally. Digital filter coefficients are estimated from modal analysis parameters, which are obtained by an optimization process that minimizes the error between measured and synthesized admittances, and between measured and synthesized radiativity profiles. Filter coefficients are then used in a digital waveguide synthesis model to render plucked string sounds
