maad.sound.avg_amplitude_spectro

maad.sound.avg_amplitude_spectro(Sxx_ampli)[source]

Computes the average of an amplitude spectrogram along the time axis.

Parameters:
Sxx_ampli2d ndarray of floats

Amplitude spectrogram [Matrix]

Returns:
S_ampli_mean1d ndarray of floats

Amplitude spectrum [Vector]

Examples

>>> w, fs = maad.sound.load('../data/rock_savanna.wav') 
>>> Sxx_amplitude,tn, fn, ext = maad.sound.spectrogram (w, fs, mode="amplitude")

Compute mean amplitude spectrogram

>>> S_amplitude_mean = maad.sound.avg_amplitude_spectro(Sxx_amplitude)
>>> S_amplitude_mean
