How do I remove one audio stream from an AVI file?

I have several AVI files that have dual audio in Russian/English. The default audio is Russian, and I want to change the default language or remove the Russian language from these AVI files.

How could I achieve this? I don't want to change the audio stream every time I play the movie.

Are there any free tools?

I was able to do this with the Avidemux (GUI) program

Main menu: Audio -> Select track; you select the tracks you want to keep, and save as a new file.

Just in case, Avidemux is in the standard Fedora Linux repository; I'm sure it is standard in Ubuntu/Debian, too.

ffmpeg (console) is also able to do this:

$ ffmpeg -i file.avi -map 0:0 -map 0:3 -acodec copy -vcodec copy file.1-track.avi

(keeping the video track, and audio track #3), but on one of my files the resul I got with Avidemux was better.

VirtualDubMod also provides the ability to choose which audio streams you want to keep (after selecting the audio stream, you can set the video and audio options to direct-copy, then save it). Of course if the AVI has VBR audio, it may have audio-sync problems because VDubMod has not been updated in a long time and doesn’t support it, and nandub which does support VBR audio, doesn’t have a way to (easily) select which audio stream you want.

Avidemux has the (limited) ability to use dual audio tracks, so it should also be able to select one from two.
