Use That File As Audio Track [top] | Avidemux Cannot
Let’s walk through two real-world scenarios.
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
Avidemux is highly sensitive to file formats, container constraints, and audio encoding properties. The error usually stems from one of three main issues:
Avidemux might not have the built-in demuxer or decoder required for the specific audio format or variant you are importing. avidemux cannot use that file as audio track
What the error means
The most reliable solution is to re-encode your audio file into a format that Avidemux natively accepts without issue.
By switching the container to MKV, you often bypass the strict header requirements of the MP4 container, allowing Avidemux to accept the audio file. Let’s walk through two real-world scenarios
Ensure that your audio file is in a compatible format. You can check the audio file format by:
The "Cannot use that file as audio track" error is a sign of a fundamental incompatibility, not a bug. By understanding that Avidemux works with raw, elementary audio streams and not container files, you can easily resolve the issue. The simplest and most reliable fix is to convert your audio file to a compatible 16-bit WAV file using a free tool like FFmpeg or Audacity. This process ensures your project can proceed and that your final video will have the audio you intended. For many users, the even simpler alternative is to bypass the issue entirely and use a tool like MKVToolNix to mux the files together without any conversion. With these solutions at hand, that frustrating error message will be a thing of the past.
The good news is that even if your audio file is unsupported, the solution is straightforward: you need to convert it into a compatible format. This is a simple process that can be done with free, widely-available tools. The error usually stems from one of three
This command copies the audio stream ( -acodec copy ) but discards all global metadata from the file ( -map_metadata -1 ), leaving you with a clean stream that Avidemux can read more easily.
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:
If the audio sampling rate (e.g., 48kHz) differs significantly from the video's expectations, it may reject the file.
If you're working with the MKV (Matroska) container, MKVToolNix is the most reliable muxer.
