Constructor Detail

PinkNoise

public PinkNoise()

Constructs a pink noise signal with an amplitude of 1.

PinkNoise

public PinkNoise(float amp)

Constructs a pink noise signal with an amplitude of amp. amp should be between 0 and 1.

Parameters:

amp -

Method Detail

setAmp

public void setAmp(float a)

Sets the amplitude of the signal to a.

Parameters:

a - the new amplitude, it will be constrained to [0, 1].

setPan

public void setPan(float p)

Sets the pan of the signal to p.

Parameters:

p - the new pan, it will be constrained to [-1, 1]

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
