TonalityECMA418_2#

class ansys.sound.core.psychoacoustics.TonalityECMA418_2(signal=None)#

Computes ECMA 418-2 tonality.

This class is used to compute the tonality according to the ECMA 418-2 standard (Hearing Model of Sottek), formerly known as ECMA 74, annex G.

Class instantiation takes the following parameters.

Parameters:

signal: Field, default: None: Signal in Pa on which to calculate the tonality.
