| Problem / Error Scenario | Root Cause | Step-by-Step Solution | | :--- | :--- | :--- | | | The file is an MP4 container. Avidemux cannot unpack it. | 1. Extract the Raw Audio Stream : ffmpeg -i in.m4a -c copy out.aac 2. Add the New .aac File : In Avidemux, go to Audio > Select Tracks and add your new raw file. | | Adding a .flac or .ogg File | The audio codec is not supported by Avidemux's audio muxer. The Vorbis codec in .ogg files is only supported when re-encoding an existing audio track. | 1. Convert to a Supported Format : Use FFmpeg: ffmpeg -i input.flac -c:a pcm_s16le output.wav 2. Add the New .wav File : This lossless conversion yields a raw format Avidemux can use. | | Adding a .wav File and Crashing | The .wav file uses an unsupported bit depth, such as 32-bit integer or 32-bit float. | 1. Convert to a Compatible WAV : Use Audacity or FFmpeg to re-encode the WAV as 16-bit or 24-bit signed integer PCM . 2. Add the New .wav File : Avidemux is much more reliable with these standard depths. | | Adding an .mp3 File with Metadata | Metadata from programs like Traktor or "ID3v2" tags can confuse Avidemux's MP3 frame header detection. | 1. Remove Metadata : Use a tool like Mp3tag to remove all tags and cover art from the MP3. 2. Try a Nightly Build : If this fails, download the latest Avidemux Nightly build, which has improved detection to ignore large tags. | | General Audio Format Incompatibility | Your file (e.g., DTS) may not be on the list of formats Avidemux can handle as an external track. | 1. Convert to WAV : Encode the file to a 16-bit or 24-bit PCM WAV file. 2. Check Bitrate : For MP3, try using a standard bitrate like 128kbps or 192kbps. |

The error "Avidemux cannot use that file as audio track" is not a bug but a constraint of the software’s simplistic muxing engine. By converting the external audio to with a matching sample rate and zero start time, users can reliably add external tracks. For complex multi-track audio editing, a different tool (e.g., Shotcut, DaVinci Resolve, or FFmpeg command line) is recommended.
