Understood, one trick is to shift the whole content sideways 50% 
before doing the FFT so that the phase information you get is on 
the center of the bellshaped top of the window function. Which 
simplifies calculations.

(IIRC simpler effects can be done with 50% overlap, and 75% for 
more general usage.)
