I'm computing discrete short time Fourier transform. Data is split into overlapping chunks and gaussian window is used for each chunk. However, I'm not sure how much overlap there should be between chunks.
If they are too sparce I will loose information between them (gaussian window for each chunks is shown here):
On the other side, pack them to densely and I will do a lot of redundant computations:
Something in between is necessary:
But what exactly should it be?
