By understanding the relationship between audio codecs, container formats, and Avidemux’s “Copy vs. Encode” behavior, you’ll never be blocked by this error again. Keep a copy of FFmpeg or Audacity handy, and you can convert any audio file to an Avidemux-friendly track in under a minute.
Happy editing!
