Pitch Recognition in a Polyphonic Context

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 to define the sounds in the polyphonic recording as well as the different pitches.

Applications relate to musical analysis, polyphonic sound processing, instrument recognition, and the separation of sound sources.
