how to split /merge audio channels ?

[ktnwin]

I am totally new to audio processing, please help with my questions here:
1) is there a way to split a stereo audio file (.WAV) into two mono .wav files ?
2) the opposite: is there a way to combine two mono .wav files into a single stereo .wav file ?
3) and what is (are) the software for this purpose ? (freeware preferrerable)
Thanks

You can switch between right and left channels, select, copy and paste to a new file in mono...or do the opposire as well....

shareware, but doesn't expire
