  (Asked by: username_0 on 2016-05-26)
  
  I have an animated movie in three different languages. The picture is exactly the same for each langauge, only the audio is different.
  
  I want to merge all these files into one, so that I have a single video file where I can switch easily between the audio tracks in VLC.
  
  How can I merge the audio tracks into a single file?
  
  I can use any OS for the job, but my preferred order is:
  
  1. OS X
  2. Linux (Debian/Ubuntu/Mint)
  3. Android
  4. iOS
  5. Windows desktop
  
  It's not really important, though, I'll take suggestions for any platform happily.

  FFMPEG can do it. FFMPEG is command line video (and audio) processing software, available [here](http://ffmpeg.org).
  
  If you have FFMPEG here is the command you would use:
  
  ```
  ffmpeg -i video.avi -i audio1.mp3 -i audio2.mp3 -map 0 -map 1 -map 2 -codec copy output
  
  ```
