[SoX-users] Mac OS X beginner seeks support for SoX and scripting: splitting 2-channel .wav´s in two .mp3´s

[Alfred M. <alf...@we...>]

Hello,

I am new to Mac OS X and scripting.

I am recording talks as .WAV files with left channel speaker´s voice and 
right channel translator´s voice.
Once in a while I want to split the .WAVs into two .MP3s with same 
filename but in folders ./speaker/*.MP3 and ./translation/*.MP3.
I solved that for windows with a batch file, onto which I drag and drop 
a set of files and the batch does the job (see batch below).

Now I need the same funcion on a Mac. I welcome any support to ease the 
implementaton:
- I have a folder with SoX for Mac OSX
- A script seems to be the equivalent to the batch. Hints for an easy 
start? Which scripting tool? How to call SoX? How to pass the files to 
split?
- I got a LAME-library libmp3lame.lylib from 
http://www.thalictrum.com/en/products/lame.html. Will this work and 
where do I place it?

Thanks
Alfred

And here the windows batch file
