I really wonder what is the point to do such a thing in Pd - there  
are different tools for different task, 'one size fits all' is an  
almost religious illusion...

audacity does changing file types better than any app that I know.  
there's to the left side of the window at the name of the file a pull  
down window that allows you to split, glue together etc exactly as  
you want to.

solo the tracks that you want to export as stereo, click "make left"  
the one you want to be left and "make right" you want to be right.  
than click "make stereo" and export. and then the next pair of tracks.
