How to extract one language from multilangual .mov file

[Akasashasha]

Hello dears,

I've been working long on Mac and it was possible with quicktime 7 to delete audio files in multilingual .mov files in order to have only one / two language.  Need an example  ?
- got a .mov file with 5 different languages (let say english, french, german, spanish, italian)
- I want 5 different video files as output : one with english, one with english and french, one with english and german, etc ...

got it ? 
so is that possible with Avidemux ? I'm looking for a software who can do that in Windows (Windows 10 to be more precise)
and if possible to do the other way around (meaning adding audio files to a video), would be great to find out how.

thanks and love

AK

Avidemux can handle 4 audio tracks.
The missing audio track you would need to extract with audio editor like audacity + its FFmpeg import/export library.
You could then import in avidemux the extracted audio track.

thanks for this info ... but it's not exactly what I'm asking, I'll try to be more precise:
- got a .mov video for a public talk with 4 translation in it
- when opening in Avidemux, I only find the first audio with speaker language, other ones do not appear, I can't hear them
- how to import in Avidemux a .mov multilingual file properly so that all translation files (tracks) are included ?
- once imported in Avidemux, how to select the audio file I want to hear and delete (or deselect) other audio files ?

Audio --> Select Track. The first active one is played.

load video, possibly up to 4 audio tracks are discovered

- once imported in Avidemux, how to select the audio file I want to hear and delete (or deselect) other audio files ?

see previous answer from eumagga0x2a
Menu: Audio: Select Track: Make you choice

enabled tracks are saved, disabled not.
