WebSpecifically, STFT and ISTFT operations are implemented as 1-D convolution and deconvolution layers consisting of fixed filters initialized with the discrete Fourier transform matrix. How would I go about implementing an STFT and an ISTFT as a 1-D convolution and 1-D deconvolution respectively?

Webtorch.istft(input, n_fft, hop_length=None, win_length=None, window=None, center=True, normalized=False, onesided=None, length=None, return_complex=False) → Tensor: Inverse short time Fourier Transform. This is expected to be the inverse of stft (). WebTo calculate STFT, Fast Fourier transform window size(n_fft) is used as 512. According to the equation n_stft = n_fft/2 + 1, 257 frequency bins(n_stft) are calculated over a window size of 512. The window is moved by a hop length of 256 to have a better overlapping of the windows in calculating the STFT.
