How to Reverse Audio in Kdenlive

This article provides a quick, step-by-step guide on how to reverse the playback of an audio clip directly on the Kdenlive timeline. You will learn how to use Kdenlive’s built-in speed properties to backward-play any audio file or audio track in just a few clicks, without needing external audio editing software.

Step 1: Prepare Your Audio Clip on the Timeline

First, ensure your audio clip is positioned on the Kdenlive timeline. If your audio is currently linked to a video clip, you must separate them to reverse only the audio. To do this, right-click the combined clip on the timeline and select Ungroup Clips (or press Ctrl + Shift + G). You can now select and edit the audio track independently.

Step 2: Open the Change Speed Menu

Right-click on the specific audio clip you wish to reverse. From the context menu that appears, select Change Speed. This will open a small configuration window.

Step 3: Enable the Reverse Option

In the “Change Speed” dialog box, you will see options for speed percentage and pitch compensation. To reverse the audio: 1. Locate the checkbox labeled Reverse play. 2. Check the box to enable it. 3. Keep the speed at 100% if you want the audio to play backward at its original tempo, or adjust the percentage if you want to speed up or slow down the reversed audio. 4. Click OK to apply the changes.

Step 4: Preview and Render

Once applied, Kdenlive will update the clip on the timeline. You will see a small indicator on the clip (often displaying a negative speed percentage, such as -100%) showing that the playback direction has been reversed. Press the Spacebar to play the timeline and preview your reversed audio effect.
