: Certain codecs, such as Vorbis or specific AAC variants in proprietary Apple formats, may not be supported for external insertion without first being re-encoded or extracted.
The "Avidemux cannot use that file as audio track" error is not a bug but a feature of Avidemux's specialized design. It is an excellent tool for simple video cutting and copying, but its audio handling is very strict. By understanding the difference between containers and raw streams, and by pre-processing your audio with FFmpeg or Audacity, you can consistently and successfully add external audio tracks. If your workflow becomes too complex, however, do not hesitate to switch to a tool like Shutter Encoder or MKVToolNix for a more flexible approach.
For output, there is a dedicated Audio -> Second audio track feature. This track must be an MP3 CBR or AC3 file.
: Avidemux officially supports external tracks in raw WAV (16/24-bit) , MP3 , AC3 , E-AC3 , MP2 , DTS , and AAC (ADTS-encapsulated) . Step-by-Step Solutions 1. Convert to a Raw Format avidemux cannot use that file as audio track
FFmpeg is a powerful command-line tool. Here are the most effective commands:
Q: Why can't I add an audio file to my Avidemux project? A: The "Avidemux cannot use that file as audio track" error can occur due to incompatible audio formats, corrupted files, or unsupported codecs.
WAV (16-bit) is the most reliable for import because it is uncompressed. MP3 (Constant Bit Rate) is also widely supported. : Certain codecs, such as Vorbis or specific
If you are trying to use a very modern or obscure codec (like Opus or certain flavors of AAC), Avidemux might not have the specific demuxer needed for that standalone file. Converting to or WAV usually solves this. 📥 How to Properly Add an Audio Track Once you have your compatible file (preferably WAV or MP3): Open your video file in Avidemux. Click the Audio menu at the top. Select Select Track . Find an empty track (or the one you want to replace). Click the dropdown menu and select Add audio track . Browse to your file and click Open .
If the audio file's sample rate is invalid (e.g., 44.1 kHz vs 48 kHz) or if the audio file is significantly shorter or longer than the video, Avidemux may fail to load it. Solutions: Fixing the Audio Track Error
: If your video project is strictly expecting a standard 44.1 kHz or 48 kHz stream, and you attempt to force an unusual or corrupted sample rate, the application's muxer will throw an error. By understanding the difference between containers and raw
In this article, we will explore why this error happens and provide three distinct methods to fix it so you can finish your project.
While Avidemux supports many formats, certain modern or proprietary versions of AAC or Opus can occasionally cause issues depending on your version of the software. Step-by-Step Solutions 1. Convert the Audio to a Standard Format
Think of an audio container file, like an MP4 or MKV, as a shipping box. Inside the box is the actual audio stream, but the box has its own complex labeling and structure. Avidemux's audio muxer is designed to directly pick up the raw audio product on the factory floor, not to unpack a box that's been taped shut first.
Avidemux expects raw audio streams. If you try to import an .m4a or an .mp4 file as an audio track, it will fail because these are containers, not raw streams.
