Avidemux+cannot+use+that+file+as+audio+track

ffmpeg -i your_audio.mp3 -ar 48000 -ac 2 -c:a pcm_s16le output.wav

Or to CBR MP3:

ffmpeg -i your_audio.opus -ar 48000 -b:a 192k output_cbr.mp3

In the left sidebar, set Audio Output to PCM. PCM is uncompressed WAV. It works with everything.

Check if the audio file is corrupted or damaged. Try playing the file in a media player, such as VLC or Windows Media Player, to see if it plays correctly. If it doesn't play, you may need to re-encode the file or obtain a new copy. avidemux+cannot+use+that+file+as+audio+track

This error appears when Avidemux can’t import or use the selected audio file as the audio track for your project. Below are concise causes and step-by-step fixes.

Avidemux differs from Non-Linear Editors (NLEs) like Premiere Pro or DaVinci Resolve. In those programs, the software automatically converts audio to match the project settings. Avidemux, however, is designed to be a "direct stream copy" editor. It prefers not to re-encode data unless absolutely necessary. ffmpeg -i your_audio

When you see the "Cannot use that file as audio track" error, it usually means Avidemux does not have a decoder installed or activated that can read the specific format of your audio file.

The most common culprit? AAC audio wrapped in an M4A container. Or to CBR MP3: ffmpeg -i your_audio

Avidemux has a complex history with AAC audio due to licensing issues. While it can often play AAC audio inside a video file, it may struggle to import a standalone AAC/M4A file as an external track if the specific internal decoder isn't loaded.
