<p>Apparatus for audio processing comprises: a beat tracking module for identifying beat time instants in an audio signal and a downbeat identifier for identifying downbeats occurring at beat time instants, each downbeat corresponding to the start of a musical bar or measure. A pattern identifier identifies two or more adjacent bars or measures containing musical characteristics which repeat within the audio signal, the pattern identifier being configured to: generate for each downbeat a plurality of scores using respective analysis methods for indicating different characteristics within the audio signal at the downbeat; combine the scores for each downbeat; and identify based on the combined scores non-adjacent downbeats that correspond to the start of a musical pattern.</p> |
