Very cool.  I find myself needing to pitch shift something, rather my 
friends ask me to do this for them, a few times a year.  Quite a long 
time ago I found the real-time time stretcher in Snd to be quite good 
compared to the same in either SoX or Audacity.  Would you have any 
feel for how Rubber Band compares to any of these three programs?

Yeah, I know I need to find out for myself, and I will .....

Thanks again Chris!
