Avidemux+cannot+use+that+file+as+audio+track !!top!! -

The "Cannot use that file as audio track" error in Avidemux typically occurs because the software is highly restrictive about the containers and codecs it accepts for external audio streams. Core Reasons for the Error

Muxed Containers (M4A, MP4, MKV): Avidemux cannot use audio files already "wrapped" in a container like .m4a or .mp4 as an external track. It lacks the internal demuxers to strip these for external loading.

Non-Raw Formats: External tracks must generally be "raw" bitstreams. For example, while standard MP3s often work, AAC files must be in an ADTS- or LATM-encapsulated format, not a standard .m4a file.

Unsupported Codecs: Certain codecs, like Vorbis (.ogg), are only supported when re-encoding an existing track and cannot be loaded as a new external source.

Metadata Interference: Files with complex metadata (e.g., Traktor ID3 tags in MP3s) can confuse Avidemux, causing it to misread the sampling rate and reject the file.

Bit Depth/Rate Issues: Some versions of Avidemux struggle with 32-bit float WAV files; using 16-bit PCM WAV is more reliable. Common Fixes

Convert to WAV: The most reliable workaround is to convert your audio file to a standard 16-bit PCM WAV using a tool like Audacity.

Use MKVToolNix: If you just need to "marry" an audio file to a video without re-encoding, MKVToolNix-GUI is often a faster, more flexible alternative that accepts most containers.

Update Software: Ensure you are using the latest version (e.g., Avidemux 2.8.1 or newer), as some file handling bugs are fixed in nightly builds.

Extract Raw AAC: If you must use AAC, use a tool like FFmpeg to extract it from its container into a raw ADTS stream before loading. Cannot use mp3 as audio track - avidemux.org

Troubleshooting Avidemux: "Cannot use that file as audio track" Error avidemux+cannot+use+that+file+as+audio+track

Avidemux is a popular, open-source video editing software that allows users to edit and manipulate video files. While it's a powerful tool, users can encounter errors, such as the frustrating "Cannot use that file as audio track" message. In this article, we'll explore the possible causes of this error and provide step-by-step solutions to help you resolve the issue.

What does the error message mean?

When you try to add an audio file to your project in Avidemux, you may encounter the "Cannot use that file as audio track" error. This message indicates that Avidemux is unable to read or import the audio file you've selected. There are several reasons why this might happen, and we'll discuss them below.

Possible causes of the error

  1. Incompatible audio format: Avidemux supports a wide range of audio formats, but it's not compatible with all of them. If your audio file is in an unsupported format, you may encounter this error.
  2. Corrupted or damaged audio file: If your audio file is corrupted or damaged, Avidemux may not be able to read it, resulting in the error message.
  3. Incorrect file path or permissions: If the audio file is located in a directory with restricted access or has incorrect permissions, Avidemux may not be able to read it.
  4. Audio file not supported by Avidemux: Some audio files, such as those with DRM protection, may not be supported by Avidemux.
  5. Outdated Avidemux version: If you're using an outdated version of Avidemux, it may not support certain audio formats or have bugs that cause this error.

Solutions to the "Cannot use that file as audio track" error

To resolve the issue, try the following solutions:

Quick checks (do these first)

  1. Open the audio file in VLC or MediaInfo to confirm codec, container, sample rate, bit depth, and that playback works.
  2. Try another known-good audio file (MP3/AAC/WAV) to confirm Avidemux itself can add audio.
  3. Ensure you’re using a recent Avidemux version (update to latest stable).

Part 3: Step-by-Step Troubleshooting Workflow

Follow this exact sequence when you see the error.

Conclusion: Don't Let the Error Stop You

The message "Avidemux cannot use that file as an audio track" is rarely a sign of a broken file. It is almost always a sign of setting mismatch between your Audio Output codec and your Output Container.

The Golden Rule to Remember: Before adding an external audio track, ask yourself:

  1. What codec is my audio file? (MP3, AAC, WAV?)
  2. Is my Audio Output dropdown set to that same codec (or to PCM)?
  3. Does my Output Container (MP4, MKV, AVI) support that codec?

If you answer these three questions correctly, Avidemux will work beautifully. If you ever get stuck, switch to MKV container and Audio Output = PCM – that combination will save you every time. The "Cannot use that file as audio track"

Happy editing.

"cannot use that file as audio track" typically occurs when attempting to add an external audio file that is in an unsupported container or format. This often happens with

files, as Avidemux requires "raw" audio streams or specific encapsulation for external tracks. avidemux.org Common Causes & Fixes Unsupported M4A/MP4 Containers

: Avidemux cannot use audio stored in an MP4 container (like

files) as an external track. You must provide the audio as a raw stream, such as ADTS-encapsulated AAC High Bit-Depth WAV Files : If you exported a 32-bit float WAV from an editor like , Avidemux may reject it. Converting the file to 16-bit PCM WAV usually resolves the issue. Metadata Interference : Large ID3 tags or Traktor metadata at the beginning of an

Title: Troubleshooting Avidemux: How to Fix the "Cannot Use That File as Audio Track" Error

Avidemux is a favorite tool for video editors who need quick, lossless cuts and simple format conversions. It is lightweight, open-source, and powerful. However, users occasionally encounter a puzzling error message when trying to add external audio to a video project: "Cannot use that file as audio track." Incompatible audio format : Avidemux supports a wide

This error is frustrating because it halts your workflow immediately, and the error message itself offers very little explanation. If you are staring at this prompt, don't worry. It is rarely a sign of a broken installation. Instead, it is usually a technical mismatch between your video project settings and the audio file you are trying to import.

Here is a breakdown of why this error happens and how to fix it.

Step 5: Add the External Track

Go to Audio > Select Track or Audio > Main Track > External. Navigate to your .mp3, .wav, or .m4a file.

Does it work now? If yes, the problem was a codec mismatch. You can now change Audio Output from PCM to Copy or MP3 and test again to find the optimal setting.

Does it still fail? If PCM fails, your audio file is severely corrupted or in an exotic format (like ALAC or DTS). Proceed to Step 6.

Alternative: Replace Audio Without Avidemux’s “External Track”

If you keep getting the error, bypass it entirely:

  1. In Avidemux:

    • Video → Copy
    • Audio → Track 1 → Copy (keep original video audio as placeholder)
    • Output format: MP4 Muxer or MKV Muxer
    • Save as temp_video.mkv

  2. Use FFmpeg to replace the audio:

ffmpeg -i temp_video.mkv -i fixed_audio.wav -c:v copy -map 0:v:0 -map 1:a:0 -c:a aac -shortest final_video.mp4

This avoids Avidemux’s external audio limitation completely.
