Constructor Detail

WhiteNoise

public WhiteNoise()

Constructs a white noise generator with an amplitude of 1.

WhiteNoise

public WhiteNoise(float amp)

Constructs a white noise generator with the given amplitude. amp should be between 0 and 1.

Parameters:

amp - the amplitude

Method Detail

setAmp

public void setAmp(float a)

Sets the amplitude to a. This value will be constrained to [0, 1].

Parameters:

a - the new amplitude

setPan

public void setPan(float p)

Sets the pan to p. This value will be constrained to [-1, 1].

Parameters:

p - the new pan

generate

public void generate(float[] signal)

Description copied from interface: AudioSignal

Fills signal with values in the range of [-1, 1]. signal represents a mono audio signal.

Specified by:

generate in interface AudioSignal

Parameters:

signal - the float array to fill

generate

public void generate(float[] left,
                     float[] right)

Description copied from interface: AudioSignal

Fills left and right with values in the range of [-1, 1]. left represents the left channel of a stereo signal, right represents the right channel of that same stereo signal.

Specified by:

generate in interface AudioSignal

Parameters:

left - the left channel

right - the right channel
