The Sliding Discrete Fourier Transform (SDFT) is a recursive approach to compute the Fourier transform sample by sample. In this particular case it's more efficient than the FFT based Short Time Fourier Transform (STFT) approach with one sample hops.

"Webb8 okt. 2003 · In this paper, we propose a novel noise reduction of speech signals using sliding DFT (SDFT) which is based on the spectral subtraction method. The spectral subtraction method reduces noise by subtracting the spectrum of noise estimated from an input signal and is a relatively simple and effective technique. " - Sdft python

The DFT bin refers to a frequency range centered at each of the N output points. The width of the bin is sample rate/2, and it extends from: center frequency - (sample rate/N)/2 to center frequency + (sample rate/N)/2. In other words, half of the bin extends below each of ...
