How to Extend or Shorten Music with the Remix Tool in Premiere Pro
Timing your music to match a video cut used to require slicing, fading, and hoping it hit the beat just right. But Adobe Premiere Pro now includes a powerful feature that simplifies the process—the Remix Tool. This lets you stretch or shorten music tracks automatically to fit the length of your timeline.
In this guide, you’ll learn how to use the Remix Tool for quick, flexible audio edits without the manual hassle.
Why Use the Remix Tool?
The Remix Tool is great when you:
Need a music track to end exactly with your footage
Want to make audio fit a timed segment without noticeable cuts
Are working on fast-turnaround projects like reels, corporate videos, or event recaps
Don’t want to manually trim, fade, or loop audio
It analyzes the song’s structure and remixes it while preserving rhythm and transitions.
Step 1: Open the Remix Tool
If the Remix Tool isn’t already visible:
Go to Window > Tools
In the toolbar, click and hold the Ripple Edit Tool
From the dropdown, select the Remix Tool
This tool will now be active in your timeline.
Step 2: Use the Remix Tool to Adjust Audio Length
Once the Remix Tool is active:
Select your music track
Click and drag the edge of the clip left or right
Premiere will automatically remix the audio to fit the new length
You’ll see the waveform regenerate as the new timing takes effect. It's fast and surprisingly accurate for most background music.
Step 3: Add a Fade-Out
To polish the transition:
Right-click the end of your audio clip
Select Apply Default Transition
This will add a fade-out so the music ends smoothly
Great for scenes like dance sequences, product reveals, or interview fade-outs.
Step 4: Precision Tips
While the Remix Tool is excellent, it may not always hit exact frame lengths:
If your target time is highly specific (like 1:29:00), the tool may overshoot or undershoot
In these cases, try adjusting the handle slightly and testing different endpoints
Not all songs remix well, so results may vary depending on the structure of the track
For songs that need perfect timing or a precise musical resolution, manual editing may still be needed.
That’s How It’s Done
The Remix Tool is one of the best time-saving features in Premiere Pro. It gives beginner editors the ability to match audio length to a cut without digging into music editing skills.
