AbstractWe present a method for segmenting musical audio signals with respect to a particular metrical level the beat. No assumption has been made regarding sound sources. We situate this proposal with respect to recent models. The model proposed seeks recurrences in values of audio signal low-level features. These features are computed at the scale of the smallest metrical level the tick --or tatum. Focusing on energy features in frequency subbands gave better results than on the whole frequency range. An attractive aspect of the method is that it permits to evaluate the relevance of any low-level feature as a cue for beat induction
