I’ve noticed that the Hamming window (and I suppose other windows) provided by Octave, SciPy****, and NumPy***** is wrong, returning a window that is symmetric rather than one that is “DFT symmetric.” This is easily spotted by looking at the first and last points of the window; if they are the same values, then the window is incorrect.
def get_window(window, Nx, fftbins=True): # snip sym = not fftbins
