WebJul 16, 2015 · In matlab it would be as easy as fft (hamming (L),N) where L is the length of the window (in time samples) and N is the number of bins in the fft (it is better to be a power of 2). I hope this clarifies a little bit the use of windows and don't hesitate to comment if it is still not clear enough.
