PeriodicWave.PeriodicWave()

The PeriodicWave() constructor creates a new PeriodicWave object instance.

Syntax

var myWave = new PeriodicWave(context, options);

Parameters

context

A BaseAudioContext representing the audio context you want the node to be associated with.

options Optional

A PannerOptions dictionary object defining the properties you want the PannerNode to have (It also inherits the options defined in the PeriodicWaveConstraints dictionary.):

• real: A Float32Array containing the cosine terms that you want to use to form the wave (equivalent to the real parameter of AudioContext.createPeriodicWave).
• imag: A Float32Array containing the sine terms that you want to use to form the wave (equivalent to the imag parameter of AudioContext.createPeriodicWave).

Example

var real = new Float32Array(2);
var imag = new Float32Array(2);
var ac = new AudioContext();

real[0] = 0;
imag[0] = 0;
real[1] = 1;
imag[1] = 0;

var options = {
  real : real,
  imag : imag,
  disableNormalization : false
}

var wave = new PeriodicWave(ac, options);
