Choosing the right overlap for a window function On Wikipedia there is quite a list of window functions.  However, when you are doing a lot of STFTs, you often have to have some overlap to get better results.

Generally an overlap factor of 2 (i.e., 50% overlap) works fine (I'm doing analysis &amp; resynthesis), but for some windows it isn't good (I currently have this experience with the Blackman window).

I tried my best but I couldn't find a resource that would list the "good" overlap factors for common and less common windows.
Please refer to this paper on the optimum overlap percentage for the Blackman-Harris window, which is derived to be 66.1%. It has a lot of useful information on spectral analysis and windows.
