multiple language wavs

[androoz]

i just want to know what program to use to combine two wav files into one... eg left channel is ENGLISH and right channel is CHINESE or something...

You need Sonic Foundry's Sound Forge.

Or Audicity, it can handle up to 5 channels (or more?) and you can easilie selct which output-channel it should be. But for most video-solutions it's more usefull to use separate wav-files for each language and let the player do the rest.
