|Modeling the Spectral Envelope of Musical Instruments
|The spectral envelope is one of the most important features contributing to the notion of timbre. Mathematical models of the envelopes constitute an important source of a-priori knowledge for applications such as automatic transcription, classification or source separation, and allow the characterization of timbre perception. In this presentation, the demands of such a generalized representation will be analyzed, and several strategies aimed at that goal will be compared. The results of recent research on this topic at the Équipe Analyse/Synthèse will be presented, together with an outlook to future work.
