Avidemux Cannot Use That File As Audio Track -
| Possible Cause | Explanation | |----------------|-------------| | Unsupported audio codec | Avidemux expects PCM (uncompressed) or specific compressed formats (MP2, AC3, AAC). Some MP3 or AAC files with exotic encoding settings may be rejected. | | Sample rate mismatch | Avidemux internally works with certain sample rates (e.g., 44.1 kHz, 48 kHz). Rare rates (8 kHz, 96 kHz) may cause failure. | | File structure corruption or non-standard headers | Not all WAV or MP3 files strictly follow standard headers (e.g., WAV with extra chunks). | | Multi-channel layout not supported | Avidemux has limited support for 5.1/7.1 channels when adding external audio; stereo/mono is safest. | | Container-wrapped audio | Using a video file (e.g., MKV with audio) as the “audio track” will fail unless the internal stream is truly raw-audio compatible. | | File permissions or path issues | Non-ASCII characters in path, network drive with slow access, or read-only attribute. |
If you are trying to add an external audio file to a video project in Avidemux and are met with the error message "Cannot use that file as audio track," you are not alone. This is one of the most common frustrations users encounter with this otherwise lightweight and efficient video editor.
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.
In this article, we will explore why this error happens and provide three distinct methods to fix it so you can finish your project.
If your video’s original audio is 48 kHz (standard for video), but your external audio file is 44.1 kHz (standard for CD audio), Avidemux sometimes refuses to combine them without resampling. Since Avidemux does not resample on the fly, it triggers an error.
If none of the above solutions work, try using a different audio file to see if the issue is specific to the file.

FAQs
Q: Why can't I add an audio file to my Avidemux project? A: The "Avidemux cannot use that file as audio track" error can occur due to incompatible audio formats, corrupted files, or unsupported codecs.
Q: What audio formats are supported by Avidemux? A: Avidemux supports WAV, AIFF, MP3, and AAC audio formats.
Q: How do I convert an audio file to a compatible format? A: You can use tools like FFmpeg or online audio converters to convert your audio file to a compatible format.
The error "Cannot use that file as audio track" in Avidemux typically occurs because the software has strict requirements for external audio streams. Unlike standard media players, Avidemux often expects "raw" audio streams rather than audio already wrapped in another container like .m4a or .mp4. Core Causes for the Error
Container Conflict: Avidemux cannot demux external containers (like .m4a) to use them as simple audio tracks. It treats .m4a as a video container without video, which it doesn't support as an external input.
Metadata Interference: Certain metadata (e.g., Traktor tags) at the start of a file can confuse the software, causing it to misinterpret sampling rates and reject the file [1.2.1).
Unsupported Formats: While it supports common formats like MP3, AC3, and WAV, specific encodings like AAC must be in a raw ADTS or LATM envelope to be accepted. Step-by-Step Solutions 1. Convert to a Compatible Format
To ensure compatibility, convert your audio file to a "safer" format before importing.
Recommended Formats: WAV (16-bit) is the most reliable for import because it is uncompressed. MP3 (Constant Bit Rate) is also widely supported.
Tools: Use Audacity to open your audio and export it specifically as a WAV or MP3 (CBR) file. 2. Strip Containers from AAC If you have an .m4a file and need to keep it as AAC: You cannot import the .m4a directly. avidemux cannot use that file as audio track
You must extract the raw AAC stream into an ADTS envelope using a tool like FFmpeg or a dedicated audio converter before Avidemux will recognize it. 3. Proper Insertion Workflow
Once you have a compatible file, follow these steps to add it:
This error occurs because Avidemux requires raw audio streams when adding an external track. It cannot "demux" an external file if it is already inside a container (like .m4a or .mp4). 🛠️ Common Fixes
Convert to WAV or MP3: The most reliable solution is to convert your audio file to a standard format like 16-bit WAV or CBR MP3 before importing.
Avoid M4A files: Avidemux does not support .m4a as an external track because it is a container, not a raw stream.
Remove Metadata: High-end audio tools (like Traktor) add metadata headers that can confuse Avidemux. Re-saving the file without metadata often fixes this. 💡 How to Add the Track Correctly Once your file is in a compatible format (WAV or MP3): How to add audio to video with VLC and Avidemux
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 If you are trying to add an external
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
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. If your video’s original audio is 48 kHz
