- Don’t just ignore the error and save. The error prevents you from saving for a reason. Forcing a bad mux will crash Avidemux or produce an unplayable file.
- Don’t rename the file extension. Changing
.aacto.mp4does nothing magically. - Don’t use“Video Output = Copy” if you change resolution. That’s unrelated to this audio error, but a common confusion.
Unsupported audio codec
| Cause | Explanation | |-------|-------------| | | Avidemux natively supports AAC, MP3, PCM (WAV), AC3, and MP2 . It struggles with Opus, Vorbis, FLAC, DTS, or lossless WMA. | | Wrong container format | Even if the audio codec is fine, the container (e.g., MKV, MP4, M4A, OGG) may confuse Avidemux’s demuxer. Raw .wav or .mp3 files work best. | | Variable Bitrate (VBR) MP3 | Avidemux’s MP3 parser (based on older libraries) often fails with VBR MP3 files, especially when seeking or appending. | | Multichannel or unusual sample rates | Files with 5.1/7.1 surround, 44.1kHz (ok), 48kHz (ok), but unusual rates like 22.05kHz or 96kHz may trigger the error. | | Corrupted or incomplete audio file | A truncated download or bad rip can break Avidemux’s strict parsing. | | File path issues | Less common on modern OSes, but spaces, Unicode characters, or network drives have been known to cause this error. | Review: Avidemux — "Cannot use that file as

5. Sampling Rate or Bit Depth Issues
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.
Avidemux supports a variety of audio and video formats, but it's not exhaustive. The most commonly supported audio formats include WAV, MP3, and AAC. If your audio file is in a less common format, Avidemux might not support it.
