Constructor Detail

SineWave

public SineWave(float frequency,
                float amplitude,
                float sampleRate)

Constructs a sine wave with the given frequency, amplitude and sample rate.

Parameters:

frequency - the frequency of the pulse wave

amplitude - the amplitude of the pulse wave

sampleRate - the sample rate of the pulse wave

Method Detail

value

protected float value(float step)

Description copied from class: Oscillator

Returns the value of the waveform at step. To take advantage of all of the work that Oscillator does, you can create your own periodic waveforms by extending Oscillator and implementing this function. All of the oscillators included with Minim were created in this way.

Specified by:

value in class Oscillator

Parameters:

step - an offset from the beginning of the waveform's period

Returns:

the value of the waveform at step
