Title (EN) APPARATUS AND METHOD FOR DETERMINING A PROMINENT TEMPO OF AN AUDIO WORK
(FR) APPAREIL ET PROCÉDÉ DE DÉTERMINATION D'UN TEMPO PROÉMINENT D'UNE ŒUVRE AUDIO
Abstract:
(EN) The prominent tempo of an audio data is determined by detecting a plurality of beat rates of the audio data. One or more audio data characteristics are used to filter through the beat rates to determine the prominent tempo. Systems, methods, and apparatuses to determine the prominent tempo are discussed herein.
(FR) Le tempo proéminent de données audio est déterminé par détection d'une pluralité de fréquences de battement des données audio. Une ou plusieurs caractéristiques de données audio sont utilisées pour filtrer à travers les fréquences de battement pour déterminer le tempo proéminent. L'invention porte sur des systèmes, des procédés et des appareils pour déterminer le tempo proéminent.
