A PROCESS FOR ASSIGNING AUDIO DATA IN MISSING AUDIO PARTS OF A MUSIC PIECE AND DEVICE FOR PERFORMING THE SAME

摘要

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.
