SharpnessOverTime

class ansys.sound.core.psychoacoustics.SharpnessOverTime(signal=None, field_type='Free')

Computes the sharpness of a signal according to Zwicker & Fastl’s model, over time.

Note

The calculation of this indicator is based on the loudness model for time-varying sounds defined in the standard ISO 532-1. It is the loudness model of the class LoudnessISO532_1_TimeVarying.

Class instantiation takes the following parameters.

Parameters:

signalField, default: None

Signal in Pa on which to compute sharpness over time.

field_typestr, default: “Free”

Sound field type. Available options are “Free” and “Diffuse”.
