Have you tried a sine window for both analysis and syntheses yet? It's used in MPEG according to here:- https://ccrma.stanford.edu/~jos/sasp/MLT_Sine_Window.html Although I think it's supposed to be 'M-1' instead of M, I'm not sure

Re: [music-dsp] WOLA and the phase vocoder

Pre- and post- windows do not have to be identical. Post-windowing is more about eliminating discontinuities at the ends of a frame. It has nothing to do with DFT so one doesn't care about the spectral qualities. I use Hamming forpre-windowing and {Hann divided by Hamming} for post-windowing

[music-dsp] WOLA and the phase vocoder

As any tutorial/paper/book will teach you, one should apply the window of choice both before an FFT and after an IFFT (in order to smooth/taper to signal that might have gone wild due to frequency domain modifications). The problem is of course that this amounts to applying a squared window instead
