maad.util.kurtosis

maad.util.kurtosis(x, axis=None)[source]

Compute the kurtosis (tailedness or curved or arching) of an audio signal.

Parameters:

xndarray of floats: 1d signal or 2d matrix
axisinteger, optional, default is None: select the axis to compute the kurtosis The default is to compute the mean of the flattened array.

Returns:

kufloat or ndarray of floats: kurtosis of x if x is a 1d vector => single value if x is a 2d matrix => array of values corresponding to the number of points in the other axis

Examples

>>> from maad import sound, util
>>> s, fs = sound.load('../data/spinetail.wav')
>>> util.kurtosis(s)
