Examples

Plot a waveform of an audio signal. >>> from maad import sound >>> from maad.util import plot_wave >>> s, fs = sound.load(‘../data/spinetail.wav’) >>> ax = plot_wave(s, fs)

Use plot_wave with predifined matplotlib axes. >>> import matplotlib.pyplot as plt >>> s, fs = sound.load(‘../data/spinetail.wav’) >>> fig, ax = plt.subplots(2,1) >>> plot_wave(s, fs, ax=ax[0], xlabel=’’, figtitle=’Spinetail’) >>> plot_wave(s, fs, tlims=(5,8), ax=ax[1])
