Abstract

Un procédé de détermination de l'emplacement des battement accentués dans des pistes musicales consiste à : extraire un signal de la piste musicale ; démultiplexer le signal dans un certain nombre de canaux, le nombre de canaux correspondant à la mesure de la piste musicale de sorte que chaque canal consécutif contienne une partie consécutive du signal, chaque partie du signal correspondant à une période de battement consécutive ; et enfin, analyser le contenu de chaque canal pour déterminer le canal qui possède des propriétés de signal différentes.
