In applied mathematics, the sliding discrete Fourier transform is a recursive algorithm to compute
successive STFTs of input data frames that are a single sample
apart (hopsize − 1).[1]
Definition[]
Assuming that the hopsize between two consecutive DFTs is 1 sample,
then
From this definition, the DFT can be computed recursively thereafter.
