Signal-based Music Structure Discovery for Music Audio Summary Generation
Geoffroy G. Peeters, Xavier Rodet · University of Michigan Library Repository · 2003
Deriving directly music structure from signal analysis, without going to symbolic information, is a new subject of interest. Two approaches are studied here in order to derive the structure: the “sequence” approach, which considers the audio signal as a repetition of sequences of events – the “state” approach, which considers the audio signal as a succession of “states”. Both approaches are derived from dynamic features observations extracted from the audio signal. The obtained structures are then used for the creation of audio summary.
