Automatic audio remixing with repetition avoidance

Abstract

A digital medium environment includes an audio editing application that remixes an original audio recording to play back over a target duration. An improved audio remixing method implemented by the audio editing application comprises segmenting the original audio recording into individual beats, computing costs for transitioning between different beats of the original audio recording, and creating a remixed audio recording using the transition costs and beats of the original audio recording. As the remixed audio recording is created, transition costs are updated by assigning penalties to transitions as the transitions are inserted into the remix. Using the beats of the original audio recording with updated transition costs ensures that a remix retains a quality and structure of the original audio recording while avoiding repetition. In some implementations, the audio editing application performs remixing to extend playback of an original audio recording to a longer duration while preserving a beat-level structure of the original audio recording.
