Avidemux Cannot Use That File As Audio Track (DELUXE – 2026)

"Cannot use that file as audio track" in Avidemux typically occurs because the software is designed to accept only raw audio streams

3. Unsupported Audio Codec

Even if the file format is supported, Avidemux might not support the specific codec used within that file. avidemux cannot use that file as audio track

  1. Check file details: open the audio file in MediaInfo (or use ffprobe) to see codec, container, sample rate, channels, bit depth.
  2. Try playing the file in a media player (VLC) to verify it’s not corrupted.
  3. In Avidemux, try adding the audio via: Audio → Select Track → Add to confirm the import step.
  4. Try the same audio in a new blank Avidemux project to rule out project-specific conflicts.
  5. Test with another known-good audio file (e.g., standard MP3 or WAV) to confirm Avidemux audio import works in general.
  6. Note any console/log output from Avidemux (run from terminal) — errors there can indicate missing codec support.

Use ffmpeg (command line) or Audacity to convert: "Cannot use that file as audio track" in

AAC: Must be in an ADTS envelope (raw .aac file), not a .m4a container. AC3/E-AC3: Standard Dolby Digital formats. 2. Re-wrap with FFmpeg (Advanced) Check file details: open the audio file in

Recommendation: If you need to add an MP3 to an MP4 without re-encoding, use MKVToolNix to create an MKV file (which happily accepts MP3). Then use Avidemux to edit that MKV.

Avidemux is designed to be a "linear" editor, meaning it prefers to process video and audio streams directly without re-encoding them whenever possible. Because of this, it is notoriously picky about the format of external audio files you try to import.
