An Automator experiment that almost worked

[Darcy Burnard]

Hi everyone.  I wanted to try an expand the automator workflow that  
gets the currently open text edit document and converts it in to an  
audio file.  Here's what I wanted it to do.  Once the aiff file was  
created, it would then be opened in sound studio.  The file would then  
be saved as an aac file with a .m4a extension.  The next action would  
rename the file and change its extension to .m4b.  Finally, the file  
would get imported in to itunes.  I wanted to change the extension to  
m4b so that itunes would place it in the audio books section, rather  
then in music.
The part that didn't work was the sound studio action to save the file  
as an aac file.  What it did was it saved the file as an aiff again,  
but it threw in an m4a extension in the middle.  So it was something  
like audio.m4a.aiff.  So either I'm doing something wrong, or that  
automator action doesn't work properly.
I did a google search, and I found some other automator actions you  
could get that would convert audio files.  It appears though that they  
require quicktime pro.  I'm not apposed to buying quicktime pro, but  
I'm not sure if I'd use it for anything else.
Anyway, since we've been talking about automator quite a bit lately, I  
thought some of you might be interested in what I've been trying to  
accomplish with it.
