In Audition CC, you can create remixes of music files from a collection. For example, you can use this option for songs that change from beginning to end, and minimize abrupt changes in a song's dynamics or tempo. You can recompose any piece of music in your collection to fit the video or project duration.
Remix uses a combination of beat detection, content analysis, and spectral source separation technology, to identify hundreds of transition points in your song. It then rearranges the passages to create a composition.
Expand the Advanced section in the Properties panel to adjust the remix. The available options are:
Stretch to exact duration: This option enables time-stretch on the remixed clip and adjusts it so that it precisely matches the target duration.
Short: Short results in shorter segments, but in more transitions. This option is suited for songs that changes from beginning to end to minimize abrupt changes in dynamics or tempo.
Long: Long looks for the longest passages and smallest number of segments to minimize transitions.
Timbre: Timbre emphasizes tonal qualities in identifying transition points.
Harmonic: Harmonic emphasizes melodic and harmonic components in transition points.
Minimum Loop: Set the minimum acceptable length, in beats, to use in a segment.
Maximum Slack: Set the maximum difference in duration from your target duration.
