Stft analysis
http://musicweb.ucsd.edu/~sdubnov/Mu172/Lectures/STFTXsynth.pdf WebThis is because the STFT analysis is done using overlapping analysis windows. The windowing results in spectral leakage such that the information of individual sinusoidal components is spread over adjacent STFT bins. To avoid border effects of tapering of the analysis windows, STFT analysis windows overlap in time.
