Décompositions en éléments sonores et applications musicales

Abstract : In this paper is presented the DESAM project which was divided in two parts. The first one was devoted to the theoretical and experimental study of parametric and non-parametric techniques for decomposing audio signals into sound elements. The second part focused on some musical applications of these decompositions. Most aspects that have been considered in this project have led to the proposal of new methods which have been grouped together into the so-called DESAM Toolbox, a set of Matlab® functions dedicated to the estimation of widely used spectral models for music signals. Although those models can be used in Music Information Retrieval (MIR) tasks, the core functions of the toolbox do not focus on any specific application. It is rather aimed at providing a range of state-of-the-art signal processe soumission à Traitement du signal
