Web1 day ago · Does anyone know of any code or implementation of a differentiable bandpass filter, one that is differentiable with respect to frequency? I am trying to optimize a filterbank and need a filterbank that is differentiable with respect to the central frequency of each filter. Ideally, differentiable with respect to the width as well. Thanks, Mason.
