Hello Rob!
   I considered it, but found that converting a file with just the wrong number 
of excepted channels is much easier than working with all those phase shifts. 
I tried a few calculations to filter out the last channel or isolate on of 
th3e other two channels, but no luck. I end up with always having the third 
channel somewhere in the equation.
   Anyone any idea on how to do it mathematically speaking? And please be easy 
on me, it seems I didn't pay enough attention when it came to trigonometry. 
:-(
   Kind regards
              Julien
