Convert/Mixdown Stereo Wav to Mono Wav

Not sure about the Applescript part (I am just delving into that myself), but the method I use to output separate L and R channel mono files from a stereo interleaved in Quicktime is as follows:

1) Open the stereo file, bring up the Movie Properties window (Command-J)
2) Click the "Soundtrack" entry in the list, then click the "Audio Settings" tab
3) On the right hand side of the window is a list of Channel Assignments.
4) For your Left channel export, assign channel 1 to "Left" and channel 2 to "Unused" from the pop-up list.
5) Choose "Export" from the file menu, select "Sound to WAVE" or "Sound to AIFF"
6) Click the "Options" button, choose your setttings, and make sure that "Mono" is selected in the Channels setting.
7) Name the file "mystereo.L.wav"

Repeat steps 4-7 for the Right channel (e.g. set Channel 1 to "Unused" and Channel 2 to "Right")

Let me know if you get anywhere with the Applescript, I do this manually every week to separate L and R channels for a podcast I produce, and would love to have a more automated way to deal with it.

If you happen to find a way to script the channel assigments let me know as well, I've been trying to do that for a while, but I am also still a rookie applescripter...
