ABSTRACT:
A method and apparatus for processing audio for playback to provide a smooth transition between a beginning region of an audio track and an end region of a previous audio track is disclosed. A quantity representative of a chromagram is calculated for each of the audio tracks and the mixing points for the beginning and end regions of each audio track are identified. A quantity representative of a chromagram at the mixing point of the beginning region of the audio track and a quantity representative of a chromagram at the mixing point of the end region of the previous audio track are correlated to determine an order of audio tracks for playback and/or to determine the duration of the mix transition.
