What about the following:
is this (the almost -15dB cut in the transition from <2000Hz to >2000Hz) a “feature" of the filter?
plotted with:
bands = np.array([0, cutoff - 0.5*transition_width,
cutoff + 0.5*transition_width, cutoff + 0.5*transition_width + 2400.0, cutoff + 0.5*transition_width + 2500.0,fs/2.0]) / fs
desired = [0.5, 1, 0.3]
