Methods, system and/or computer program products for detection of a note include receiving an audio signal and generating a plurality of frequency domain representations of the audio signal over time. A time domain representation is generated from the plurality of frequency domain representations. A plurality of edges are detected in the time domain representation and the note is detected by selecting one of the plurality of edges as corresponding to the note based on characteristics of the time domain representation.

L'invention porte sur des procédés, sur un système et/ou sur des produits de programmes informatiques pour détecter une note, ce procédé consistant à recevoir un signal audio et à générer une pluralité de représentations du domaine de fréquence du signal audio dans la durée. Une représentation du domaine temporel est générée à partir de la pluralité des représentations du domaine de fréquence. Une pluralité de contours sont détectés dans la représentation du domaine temporel et la note est détectée par sélection d'une pluralité de la pluralité de contours tels que ceux correspondant à la note sur la base des caractéristiques de la représentation du domaine temporel.
