What is the formula of Gaussian window?
The coefficients of a Gaussian window are computed from the following equation: w ( n ) = e − 1 2 ( α n ( L − 1 ) / 2 ) 2 = e − n 2 / 2 σ 2 , where –(L – 1)/2 ≤ n ≤ (L – 1)/2, and α is inversely proportional to the standard deviation, σ, of a Gaussian random variable.
What is window size in Stft?
For computing the STFT, we use a Hann as well as a rectangular window each having a size of 62.5 msec.
