Title
(EN) APPARATUS AND METHOD FOR GENERATING AN ENCODED RHYTHMIC PATTERN
(FR) APPAREIL ET PROCEDE DESTINES A GENERER UN MOTIF RYTHMIQUE CODE
Abstract
(EN)
An encoded rhythmic pattern has several groups of velocity values, wherein the velocity values are sorted, such that the groups are included in sequence in an encoded rhythmic pattern. Now, the velocity values concentrated at the beginning of the encoded rhythmic pattern have a higher importance for characterizing the rhythmic gist of a piece of music than velocity values included in additional groups of velocity values. By using such an encoded rhythmic pattern, an efficient database access can be performed.
(FR)
L'invention concerne un motif rythmique codé possédant plusieurs groupes de valeurs de vitesse, ces valeurs de vitesse étant triées, de sorte que les groupes soient contenus dans une séquence d'un motif rythmique codé. A présent, les valeurs de vitesse concentrées au début du motif rythmique codé possèdent une plus grande importance dans la caractérisation du but rythmique d'une pièce de musique que les valeurs de vitesse contenues dans les groupes supplémentaires de valeurs de vitesse. En utilisant ce motif rythmique codé, un accès efficace à une base de données peut être mis en oeuvre.
