Avidemux Cannot Use That File As Audio Track ((install)) Info

Older versions of Avidemux may lack fixes for specific audio handling bugs present in newer nightly builds or releases like version 2.8.1 and above . Step-by-Step Fixes 1. Convert to a Compatible Format

Files like 32-bit WAV or DRM-protected files (often found in Apple's .m4a format) frequently trigger this rejection.

For successful "Add Audio Track" operations, aim for these specific formats: Best for quality; use 16-bit for maximum compatibility. MP3 Widely supported; ensures the file is not corrupted. AAC Must be raw .aac (ADTS), not .m4a . AC3 / DTS Supported for multi-channel audio. avidemux cannot use that file as audio track

Must be in an ADTS envelope (raw .aac file), not a .m4a container. AC3/E-AC3: Standard Dolby Digital formats. 2. Re-wrap with FFmpeg (Advanced)

The most reliable way to fix this is to transcode your audio into a format Avidemux natively supports as an external track. Use a tool like Audacity or FFmpeg to convert your file to one of the following: 16-bit or 24-bit PCM (Avoid 32-bit float). MP3: Standard constant or variable bitrate. Older versions of Avidemux may lack fixes for

Alternatively, you can mux the audio and video together directly in FFmpeg to bypass Avidemux entirely:

If you are trying to replace audio, make sure the new track is the same length as the video to avoid synchronization issues. Cannot use mp3 as audio track - avidemux.org For successful "Add Audio Track" operations, aim for

If you have a file that Avidemux won't take, you can use FFmpeg to "strip" the container and extract just the raw stream:

If an MP3 still fails, the file might have a large header. Community experts suggest that stripping the first few kilobytes of the file (which often contain non-standard metadata) can sometimes allow Avidemux to "see" the actual audio frames. Supported External Audio Tracks

Ensure you are using at least or the latest nightly build . Developers frequently release updates to handle tricky metadata in MP3 and AC3 files that previously caused this error. 4. Check File Metadata
