Remix your audio in Audition to match video duration

Learn how to use Adobe Audition from within Premiere Pro to remix or stretch a short audio clip to match your video duration.

Mixing the right background score for a video sequence is critical to its quality. As an editor, you often resort to repeating the score or cutting the music short to fit the video duration. You can now use Adobe Premiere Pro with Adobe Audition to solve this problem and produce quality results.

The following techniques in Audition help you mix an audio clip that you want to use as the background score for your video project without compromising on quality:


The Remix tool in Audition analyzes your audio file, identifies hundreds of loops, transitions, and important segments, and then allows you to quickly remix to any duration.


Stretch helps you fit audio to video sequences by speeding up or slowing down the recording.

Exporting the remixed audio back to Premiere Pro

After you complete your edits to the audio clip in Audition, you can export the clip back to your Premiere Pro project. Premiere Pro saves the edited clip separately from the original clip. 

  1. Select the remixed music track in Audition to exclude any other audio clips that were sent from Premiere Pro from the mixdown.

  2. Choose Multitrack > Export to Adobe Premiere Pro.

  3. Under Options, you can choose whether to export the mixdown session as a mono, stereo, or 5.1 file or export each track as stem. 

  4. Click Export and choose the Premiere Pro project to which you want to export the edited audio. The project opens in Premiere Pro with the mixdown track as the project’s audio track, with the original track remaining unchanged in the project panel.
