A promising approach to create new versions of existing music pieces automatically is to cut out and rearrange sections so that transitions are minimally perceptible and constraints regarding duration or structure are fulfilled. We evaluate previous work and improve on its limitations, particularly the disregard for loudness changes at cuts and the unintuitive control over the musical structure of the output. Our software provides a user-friendly interface, which we make more responsive by greatly accelerating the search for an optimal output track using the A* algorithm. Listening experiments demonstrate an improvement in perceived audio quality.
