plotPowerSpectrum

maelzel.snd.plotting.plotPowerSpectrum(samples, samplerate, framesize=2048, window=('kaiser', 9), axes=None, figsize=(24, 4))

Plot the power spectrum of a sound

Parameters:

• samples (ndarray) – the samples to plot

• samplerate (int) – the sr of thesamples

• framesize – the bigger the frame size, the smoother the plot

• window (Union[str, tuple[str, float]]) – As passed to scipy.signal.get_window. One of “blackman”, “hamming”, “hann”, “bartlett”, “flattop”, “parzen”, “bohman”, “blackmanharris”, “nuttall”, “barthann”, “kaiser” (needs beta), “gaussian” (needs standard deviation)

• axes (Optional[Axes]) – the axes to plot to

Return type:
