OscillatorNode extension type

The OscillatorNode interface represents a periodic waveform, such as a sine wave. It is an AudioScheduledSourceNode audio-processing module that causes a specified frequency of a given wave to be created—in effect, a constant tone.

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
connect(JSObject destinationNodeOrDestinationParam, [int output, int input]) → AudioNode?
The connect() method of the AudioNode interface lets you connect one of the node's outputs to a target, which may be either another AudioNode (thereby directing the sound data to the specified node) or an AudioParam, so that the node's output data is automatically used to change the value of that parameter over time.
inherited
disconnect([JSAny destinationNodeOrDestinationParamOrOutput, int output, int input]) → void
The disconnect() method of the AudioNode interface lets you disconnect one or more nodes from the node on which the method is called.
inherited
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
setPeriodicWave(PeriodicWave periodicWave) → void
The setPeriodicWave() method of the OscillatorNode interface is used to point to a PeriodicWave defining a periodic waveform that can be used to shape the oscillator's output, when OscillatorNode.type is custom.
start([num when]) → void
The start() method on AudioScheduledSourceNode schedules a sound to begin playback at the specified time. If no time is specified, then the sound begins playing immediately.
inherited
stop([num when]) → void
The stop() method on AudioScheduledSourceNode schedules a sound to cease playback at the specified time. If no time is specified, then the sound stops playing immediately.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
