Dual sound; newbie indeed.

[BiggerJim]

Hello:
I have an avi movie with dual sound and I want to remove one of the audio languages-tracks wich is annoying me. The audio format is mpeg layer-3 and the video is XVID. It's strange that I can't choose the audio track in WMP, it only plays dual sound, and in Media Player Classic or Powerdvd it doesn't sound at all.
So my question is how to edit the avi to keep only one of the languages. Any recommended tools? Do I have to edit the audio tracks by their own and then recompile the whole movie?
Thank you very much.

Is it truly a seperate audio track? I've read that there are some movies encoded on the web that play seperately in the left and right channels. You'd have to extract the whole audio track and save each channel seperately and reencode them.

If they do not play simultaneously and are indeed seperate tracks then use something like virtualdub to split out the audio file and mix into a new file. Go to file-save wav or use virtualdubmod and go to file-streams and demux the sound file that way.

Wow! Fastest support ever seen!. Thanks yoda313.
I really don't know if the audio tracks are separated. I have the tools from K-Lite Codec Pack wich may help to find out, but i don't know how to use them.
The audio stream in virtualdub file information reports:
sampling rate 48000
Channels 1 mono
sample precision N/A
mpeg layer-3 codec professional.

Does this help?

It helps us, but no you.

Open the file in Virtualdubmod, then click on Streams -> Stream List. If this confirms that you have a single, mono audio track then you are basically SOL. It means that the audio has been mixed down into a single, mono stream and you have no hope of separating it out.

Done! I'm happy and thankful to your nice support. Now I have my single audio track.
I can play the movie correctly in powerdvd and WMP, but still no sound in MPC. I must have miconfigured something...
Thanks!
