Avidemux Cannot Use That File As Audio Track Link

Review: Avidemux — "Cannot use that file as audio track" error

Summary

• Avidemux is a lightweight, free video editor focused on cutting, filtering, and encoding. A common issue users encounter is the error message: "Cannot use that file as audio track." This review explains causes, diagnostics, and fixes so you can resolve it quickly.

What the error means

• The message indicates Avidemux is unable to import or use the selected audio file or audio stream as the project’s audio track. This can occur when the audio file format, codec, container, or stream properties are unsupported, corrupted, or mismatched with the video.

Common causes

• Unsupported audio codec (e.g., newer/rare codecs not supported by Avidemux’s build).
• Container/codec mismatch: audio inside a container Avidemux can’t parse (e.g., certain MP4/AAC variants, fragmented MP4).
• Variable bit depth or sample format not handled by Avidemux.
• Corrupted or truncated audio file.
• Incorrect file selection — trying to load a video file or subtitle file as audio.
• Channel layout or sample rate unusual (very high sample rates or exotic channel counts).
• Project settings conflict (e.g., video uses parameters requiring specific audio parameters for muxing).
• Platform/build limitations (Windows/Mac/Linux builds differ; some builds lack support for particular libraries).

How to diagnose

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.

Quick fixes (ordered from simplest to more advanced)

• Use a standard format: Convert the audio to WAV (PCM) or MP3 using a converter (VLC, ffmpeg, Audacity), then import the converted file.
  • ffmpeg example:

    ffmpeg -i input.m4a -c:a pcm_s16le output.wav
    

• Re-mux the source file: If the audio is embedded in a problematic container, remux into MP4/MKV using ffmpeg: ffmpeg -i input.mp4 -c copy remuxed.mp4
• Re-encode audio to a supported codec (AAC, MP3, PCM) if codec compatibility is the issue: ffmpeg -i input.m4a -c:a aac -b:a 192k output_aac.m4a
• Repair a corrupted file: try re-encoding via ffmpeg; sometimes this fixes minor corruption.
• Use a different Avidemux build or update: install the latest stable release; some builds include newer codec support.
• As a last resort, use another editor/muxer (MKVToolNix, HandBrake, Shotcut) to combine audio and video, then open resulting file in Avidemux.

Recommended step-by-step using ffmpeg (reliable)

1. Inspect the audio: ffprobe -v error -show_entries stream=codec_name,channels,sample_rate -of default=noprint_wrappers=1 input.ext
2. Convert to WAV: ffmpeg -i input.ext -c:a pcm_s16le -ar 48000 -ac 2 output.wav
3. In Avidemux: Audio → Select Track → Add → choose output.wav

When to seek alternatives

• If you must preserve a specific codec or metadata that Avidemux doesn’t support.
• If your workflow requires advanced audio editing features — use a DAW or richer video editor.
• If Avidemux repeatedly fails despite using standard audio formats — try Shotcut or HandBrake for the muxing/encoding step.

Tips to avoid the issue

• Use common, well-supported audio formats (WAV/MP3/AAC).
• Keep Avidemux updated.
• If sharing projects between OSes, prefer remuxed MP4/MKV containers.
• When in doubt, re-encode audio to PCM WAV before importing.

Verdict

• The error is usually solvable by converting or re-muxing the audio to a standard codec/container (WAV/MP3/AAC). Avidemux remains a useful lightweight tool for simple editing, but its limited codec support means pre-processing audio with ffmpeg or using a different muxer is often necessary.

Would you like a short ffmpeg script tailored to a specific input file (tell me its filename and extension) to convert it into a compatible audio track?

The error message "Avidemux cannot use that file as audio track"

is a common hurdle for video editors using this open-source tool. It typically occurs when there is a mismatch between the file format sampling rate

of the external audio file and what Avidemux is prepared to mux into the video container Common Culprits Incompatible Containers:

While Avidemux is versatile, it can be picky about the container of the audio source. For example, trying to import a high-bitrate file into a container like

occasionally triggers a generic rejection if the header information is malformed. Compressed vs. Uncompressed:

Avidemux often struggles if the audio file uses a variable bitrate (

) or a specific proprietary codec that hasn't been properly indexed. Sampling Rate Mismatch:

If your video project is set to a specific frequency (e.g., 48 kHz) and you attempt to add an audio track with a significantly different or non-standard rate, the software may fail to bridge the gap automatically. How to Fix It Transcode First:

The most reliable solution is to convert your audio file to a standard

format using a tool like Audacity or an online converter before importing it. Check the Audio Menu: Ensure you are using the Audio -> Select Track Review: Avidemux — "Cannot use that file as

menu correctly. Sometimes, toggling the "Enabled" checkbox or manually selecting the "Add audio track" option from the dropdown menu bypasses the initial error. Update the Software:

Older versions of Avidemux have known bugs with specific audio headers. Ensuring you are on the latest stable release often resolves codec compatibility issues.

In short, this error isn't usually a sign of a "broken" file, but rather a communication gap

between the audio's metadata and the video container’s requirements.

The error "Cannot use that file as audio track" in Avidemux typically occurs because the software is unable to handle certain container formats or specific codecs when they are loaded as external tracks.  Why This Happens 

Unsupported Containers: Avidemux often cannot demux external audio that is still wrapped in a container like .m4a or .mp4. It generally requires raw audio streams (e.g., raw AAC, MP3, or AC3) rather than files meant for playback in media players.

Codec Incompatibility: Certain codecs, such as Vorbis or specific AAC variants in proprietary Apple formats, may not be supported for external insertion without first being re-encoded or extracted.

Software Version: Older versions (like 2.7.x) sometimes trigger this error for files that work in legacy versions like 2.5 or newer nightly builds.  How to Fix It  Cannot use mp3 as audio track - avidemux.org

The "cannot use that file as audio track" error in Avidemux typically occurs because the software is strict about the format and container of external audio files. Common Causes and Solutions Unsupported Audio Container:

Avidemux often fails to import audio that is already inside a container like M4A (Apple's AAC container) . It prefers "raw" audio streams. Convert your audio to a standard format like WAV (16-bit) before importing. AAC Stream Type: Avidemux is a lightweight, free video editor focused

For AAC files, Avidemux generally requires the audio to be in an encapsulation rather than muxed into an M4A file. WAV Bit Depth: If you are using a WAV file, ensure it is . Avidemux sometimes struggles with 32-bit float WAV files. Metadata Interference:

Certain metadata (like Traktor tags in MP3s) can confuse Avidemux's header detection. Strip the metadata or re-save the file using a tool like Software Version: Ensure you are using the latest stable release (e.g.,

or newer), as bug fixes for file detection are frequently added to newer builds. avidemux.org Recommended Workarounds Cannot use mp3 as audio track - avidemux.org 3 Nov 2020 —

1. Incompatible Audio File Format

Avidemux supports a variety of audio and video formats, but it's not exhaustive. The most commonly supported audio formats include WAV, MP3, and AAC. If your audio file is in a less common format, Avidemux might not support it.

• Solution: Try converting your audio file to a more widely supported format like WAV or MP3 using another software tool (e.g., Audacity, FFmpeg).

5. Sampling Rate or Bit Depth Issues

Avidemux might have issues with certain sampling rates or bit depths.

• Solution: Try converting the audio to a standard sampling rate (e.g., 44.1 kHz) and bit depth (e.g., 16-bit). FFmpeg can help with this:

  ffmpeg -i input.aac -vn -ar 44100 -ac 2 -ab 192k output.wav
  

  Adjust parameters as necessary.

How to Fix “Cannot Use That File as Audio Track”

Below are proven solutions, ranging from simple setting changes to intermediate transcoding methods.

1. Mismatched Audio Codec and Container (Most Common)

This is the culprit in 80% of cases. If your video is in an MP4 container but you are trying to add an MP3 audio track, Avidemux will often refuse. Why? The MP4 specification strongly prefers AAC audio. While some players accept MP3-in-MP4, Avidemux adheres strictly to standards.

• Example: Video = video.mp4 (H.264), External Audio = song.mp3 (MP3). Avidemux tries to copy MP3 into MP4 → Error.
