In Avidemux, go to and try adding the WAV file. 2. Check Sample Rates

ffmpeg -i input_audio.mp3 -vn -acodec pcm_s16le -ar 44100 output_audio.wav This command: Removes video data ( -vn ) Converts to standard PCM 16-bit ( -acodec pcm_s16le ) Sets the rate to 44.1kHz ( -ar 44100 )

Non-standard rates (like 22050 Hz) can trigger the "cannot use" error. 3. Strip Metadata

How to Fix "Cannot Use That File as Audio Track" in Avidemux

: Attempting to use a .m4a or .ogg file directly often fails; these should be converted to .mp3 or .wav first. 🚀 Advanced Method: Using Command Line (FFmpeg)

💡 : Always ensure you are using the latest version of Avidemux, as newer builds include updated FFmpeg libraries that handle more audio formats natively.
