Reconnaissance des hauteurs dans les sons polyphoniques

This study concerns the pitch of different sounds in polyphonic recordings.

The method used is based on frequency analyses and the statistical characterization of the sinusoidal characteristics of harmonics and sounds. A certain number of fundamental frequencies are chosen to best explain the harmonic components found and consequently define the polyphonic sounds and their different pitches. Applications are related to musical analysis, polyphonic sound processing, instrument recognition, and the separation of sound sources.
