Switch really does overall have so many functions and switches that you really need to have a general idea of what you're trying to do before you go to begin converting audio files.
The best way for us to provide a step by step process would be to tell us what it is you're trying to do so we can show you how to best go about achieving that aim. Once you've used Switch once you should be able to adaptively tell what switches do what and what seperate selections will mean.
What is it you're trying to do, friend?
