Title (EN) METHOD FOR SYNCHRONIZATION OF A MUSICAL SCORE WITH AN AUDIO SIGNAL
(FR) PROCÉDÉ DE SYNCHRONISATION D'UNE PARTITION MUSICALE AVEC UN SIGNAL AUDIO
Abstract: front page image
(EN)The present invention relates to a method for synchronization of a graphical or audible representation of a musical score with an audio signal acquired in real-time and corresponding to the performance of said musical score. This method consists of producing a spectral signature of a temporal sequence of said acquired audio signal, comparing said spectral signature with the spectral signatures of said musical score for a plurality of tempos, in order to calculate a correlation rating for each of said spectral signatures, and determining an estimated tempo corresponding to the best correlation.
(FR)La présente invention concerne un procédé de synchronisation d'une représentation graphique ou sonore d'une partition musicale avec un signal audio acquis en temps réel et correspondant à l'interprétation de ladite partition musicale. Ce procédé consiste à produire une signature spectrale d'une séquence temporelle dudit signal audio acquis, à comparer ladite signature spectrale avec les signatures spectrale de ladite partition musicale, pour une pluralité de tempo, pour calculer un score de corrélation pour chacune desdites signatures spectrales, à déterminer un tempo estimé correspondant à la meilleure corrélation.
