PeriodicWave

The PeriodicWave interface defines a periodic waveform that can be used to shape the output of an OscillatorNode.

PeriodicWave has no inputs or outputs; it is used to define custom oscillators when calling OscillatorNode.setPeriodicWave(). The PeriodicWave itself is created/returned by BaseAudioContext.createPeriodicWave.

Constructor

Creates a new PeriodicWave object instance using the default values for all properties. If you wish to establish custom property values at the outset, use the BaseAudioContext.createPeriodicWave factory method instead.

Methods
