How to Edit Kdenlive Audio in Audacity

Kdenlive is a powerful open-source video editor, but its native audio tools can sometimes be limited for complex audio restoration tasks. This guide provides a straightforward, step-by-step walkthrough on how to configure Kdenlive to seamlessly send your audio tracks to Audacity for advanced noise cleanup, equalization, and editing, and then automatically bring those enhancements back into your video project.

Step 1: Locate the Audacity Executable Path

Before configuring Kdenlive, you need to know where the Audacity executable file is located on your operating system.

• Windows: Typically located at C:\Program Files\Audacity\Audacity.exe (or C:\Program Files (x86)\Audacity\Audacity.exe).
• Linux: Usually located at /usr/bin/audacity. If you installed it via Flatpak or Snap, the path may point to the respective sandbox runner (e.g., /usr/bin/flatpak run org.audacityteam.Audacity).
• macOS: Located in your Applications folder at /Applications/Audacity.app.

Step 2: Configure Kdenlive

Once you know the path to Audacity, you can link it inside Kdenlive’s settings.

1. Open Kdenlive.
2. In the top menu, go to Settings > Configure Kdenlive (on macOS, go to Kdenlive > Preferences).
3. In the configuration window, select the Environment tab from the left-hand sidebar.
4. Click on the Default Applications sub-tab (or look for the External Applications section depending on your Kdenlive version).
5. Locate the Audio editor field.
6. Click the folder icon next to the field, navigate to your Audacity executable, select it, and click Open. Alternatively, paste the path directly into the text field.
7. Click Apply and then OK to save the changes.

Step 3: Send Audio from Kdenlive to Audacity

With the integration configured, you can now send audio clips directly to Audacity from your timeline or project bin.

1. Right-click the audio clip you want to edit. If your audio is grouped with video, right-click the clip and select Split Audio first, or simply perform the action on the audio portion of the timeline.
2. Select Edit in Audio Editor from the context menu.
3. Kdenlive will automatically extract the audio track as a lossless WAV file, launch Audacity, and open the audio file inside it.

Step 4: Clean Up and Save Your Audio

1. Perform your advanced audio cleanup (such as Noise Reduction, Compressor, or Limiter) inside Audacity.
2. Once you are finished, you must overwrite the temporary file that Kdenlive created. In Audacity, go to File > Export > Export as WAV.
3. Save the file, overwriting the existing temporary WAV file without changing its name or location.
4. Close Audacity.

Kdenlive will automatically detect the changes made to the temporary audio file and update the clip in your video timeline with the cleaned-up audio.
