摘要:
L'objet de l' invention est un procédé de gestion de flux αudionumériques d'une oeuvre musicale, consistant à créer des flux audionumériques appelés pistes (p1 à p21) d'une même oeuvre musicale, lesdites pistes ayant une durée sensiblement égale à l'œuvre musicale, chacun desdits flux audionumériques correspondant à un signal sonore, caractérisé en ce qu'il consiste, au moment de la création, à regrouper lesdites pistes en au moins deux ensembles (61 à G5), les pistes et les ensembles étant appelés éléments, à établir des contraintes relatives aux éléments, à vérif ier que chaque nouvelle contrainte est compatible avec les contraintes précédentes grâce à un moteur de résolution de contraintes, à encapsuler les pistes (p1 à p21) et les contraintes dans un fichier informatique unique, et au moment de l'écoute, à choisir les pistes que souhaite entendre l'auditeur en respectant les contraintes et obtenir un signal sonore à partir des pistes choisies.
摘要:
The aim of the invention is to provide a method for managing digital audio flows of a musical work, involving creation of digital audio flows known as tracks (p1 to p21) for a single musical work, said tracks having a duration substantially equal to the musical work, each of said digital audio flows corresponding to an audio signal, and characterized in that, when created, it comprises: regrouping said tracks into two sets (G1 to G5), the tracks and the sets being called elements; setting constraints relative to the elements; verifying, through a constraint resolution engine, that each new constraint is compatible with the previous constraints; encapsulating the tracks (p1 to p21) and the constraints in a single computer disc; and when listening, selecting the tracks desired by the listener while observing the constraints, and obtaining an audio signal from the selected tracks.

A process for assigning audio data in missing audio parts of a music piece, comprising the steps of: - execution of musical features extraction on the music piece such that the music piece is represented by a string (u) of musical features, each musical feature being represented by a sequence or a set of one or more symbols of a predetermined alphabet; - definition of a similarity measure for measuring the similarity between substrings of musical features; - definition of a substring (nu &phis; ) of missing audio parts in the string (u) of musical features; - location of at least one substring (v) of a predetermined size immediately before, respectively after the substring (nu &phis; ) of missing audio parts; - application of the similarity measure for identifying a reference substring (u 1 or u 2 ) including the at least one substring (v) of a predetermined size at its beginning, respectively at its end, the reference substring (u 1 or u 2 ) best matching to the substring (nu &phis; ) of missing audio parts; - substitution of said substring (nu &phis; ) of missing audio parts by audio data from the identified reference substring.
