SourceBroadbandNoise

class ansys.sound.core.sound_composer.SourceBroadbandNoise(file='', source_control=None)

Sound Composer’s broadband noise source class.

This class creates a broadband noise source for the Sound Composer. A broadband noise source is used to generate a sound signal from broadband noise source data and one source control.

The broadband noise source data consists of a series of noise spectra, each corresponding to a control parameter value.

The source control contains the control parameter values over time.

Class instantiation takes the following parameters.

Parameters:

filestr, default: “”

Path to the broadband noise file. Supported files are text files with the header AnsysSound_BBN.

source_controlSourceControlTime, default: None

Source control, consisting of the control parameter values over time to use when generating the sound from this source.
