The PeriodicWave()
constructor of the Web Audio API creates a new PeriodicWave
object instance.
Syntax
var myWave = new PeriodicWave(context, options);
Parameters
Inherits parameters from the AudioNodeOptions
dictionary.
context
- A
BaseAudioContext
representing the audio context you want the node to be associated with. options
Optional- A
PeriodicWaveOptions
dictionary object defining the properties you want thePeriodicWave
to have (It also inherits the options defined in the PeriodicWaveConstraints dictionary.):real
: AFloat32Array
containing the cosine terms that you want to use to form the wave (equivalent to thereal
parameter ofAudioContext.createPeriodicWave
).imag
: AFloat32Array
containing the sine terms that you want to use to form the wave (equivalent to theimag
parameter ofAudioContext.createPeriodicWave
).
Return value
A new PeriodicWave
object instance.
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);
