Frequency domain synthesis of guitar plucks for instrument making suport

Abstract

Understanding the relation between the sound quality of the classical guitar and theirphysical characteristics in depth is an important challenge for instrument makers. Never-theless, we can provide them with scientific tools that facilitate this task. Our contribution consists in measuring and modelizing - using the subspace high-resolution algorithm ES-PRIT (Estimation of Signal Parameters via Rotational Invariance Techniques) - one and two-dimensional impedance signals at the guitar bridge, which characterize the coupling between the body and the strings. The chosen synthesis technique - frequency domain synthesis - allows to keep a clear link between instrument physical parameters and theparameters of the model.
