Remix audio in Audition to match video duration

Last updated on Apr 2, 2026

Learn how to use Adobe Audition from within Adobe Premiere 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 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:

Remix

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

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

Remix the audio of your Premiere project in Audition

Adobe Premiere lets you use advanced post-production techniques available in Audition to edit audio. If you have installed Adobe Audition, you can use the Edit In Adobe Audition command to edit an audio clip in Audition, then use the Remix tool to creatively stretch the audio to match your video's duration.

Select the audio track of your Premiere project and select Edit > Edit in Adobe Audition > Sequence.

Check the audio export options, destination path, and select OK. The sequence opens in Audition.

In the Properties panel, expand the Remix tab and select Enable Remix. Audition analyzes the clip and finds the best transition points.

In the Target Duration box, type the duration of the video clip to which you want to match the audio duration and press Enter or grab the zigzag handles on either side of the clip and drag to match the duration of the video clip.

Audition remixes the audio to the target duration on the timeline.

Check the timeline for a remixed icon and Properties for the modified clip information.

Export the remixed audio back to Premiere

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

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

Select Multitrack > Export to Adobe Premiere.

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.

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

On the timeline, you can select M next to the original audio track during playback so that only the remixed track is audible.
