Caractérisation du rythme à partir de l'analyse du signal audio

Abstract : This thesis is within the scope of Music Information Retrieval. The goal of this research field is to extract meaningful informations from music. There are numerous applications: music recommendation systems, music transcription to a score or automatic generation of music. In this manuscript, oOur objective is to propose new rhythm descriptions inspired from perceptual and neurological studies.Rhythm representation of a musical signal is a complex problem. Detecting attack positions and note durations is not sufficient: we have the model the temporal interaction between the different instruments collaborating together to create rhythm. We try to obtain representations that are invariant to some parameters (like the position over time, the small tempo or instrumentation variations) but sensitive to other parameters (like the rhythm pattern or the swing factor). We study the three key aspect of rhythm description: tempo, deviations and rhythm pattern.
