Avidemux Cannot Use That File As Audio — Track

If you need to convert your audio to a compatible format, you can use FFmpeg. For example, to convert an audio file to AAC:

$$ffmpeg -i input.mp3 -c:a aac output.aac$$

This command converts input.mp3 to AAC encoded audio and saves it as output.aac.

The error “Avidemux cannot use that file as audio track” is Avidemux’s polite way of saying “give me a simple, standard audio file.” Convert your audio to 48kHz WAV or CBR MP3, and Avidemux will happily accept it.

If you need to do this frequently, create a small batch script with FFmpeg to normalize your audio files before importing. It takes seconds and saves hours of frustration. avidemux cannot use that file as audio track

The error "Avidemux cannot use that file as audio track" typically occurs because Avidemux requires external audio files to be in a raw stream format rather than a container format. While the software can handle containers like MP4 or MKV for video, it lacks the internal demuxers to unpack external audio tracks stored inside those same containers. Why the Error Occurs

Unsupported Containers: You are likely trying to import an .m4a file. In Avidemux, .m4a is seen as an MP4 container without a video track, which the software cannot process as an external source.

Metadata Interference: Large ID3 tags or specific metadata (like Traktor tags) at the start of an MP3 file can confuse Avidemux, causing it to misinterpret audio frame headers and reject the file.

Format Compatibility: Avidemux officially supports external tracks in raw WAV (16/24-bit), MP3, AC3, E-AC3, MP2, DTS, and AAC (ADTS-encapsulated). Step-by-Step Solutions 1. Convert to a Raw Format If you need to convert your audio to

The most reliable fix is to convert your audio file into a format Avidemux natively accepts using a tool like Audacity or VLC.

For AAC/M4A files: Convert them to WAV or MP3. If you must use AAC, ensure it is exported as a raw ADTS stream rather than an .m4a container.

For MP3 issues: Re-saving the file in an editor like Audacity can strip away problematic metadata that might be causing the "cannot use" error. 2. Properly Add the External Track

Once you have a compatible raw file, follow these steps to add it: Cannot use mp3 as audio track - avidemux.org If you need to do this frequently, create

When encountering the error "Avidemux cannot use that file as audio track," it typically indicates that Avidemux is having trouble processing or is incompatible with the specific audio file you've tried to add to your project. This issue can arise due to several reasons, ranging from incompatible file formats to corrupted files. Let's break down the potential causes and solutions:

While modern video tools handle VBR well, Avidemux can struggle with VBR MP3 or AAC files as external tracks. Because VBR files have inconsistent frame-to-frame bitrates, Avidemux cannot calculate exact sync points when muxing, leading to rejection.

Even if the file format is supported, Avidemux might not support the specific codec used within that file.
