AudioScheduledSourceNode extension type

The AudioScheduledSourceNode interface—part of the Web Audio API—is a parent interface for several types of audio source node interfaces which share the ability to be started and stopped, optionally at specified times. Specifically, this interface defines the AudioScheduledSourceNode.start and AudioScheduledSourceNode.stop methods, as well as the AudioScheduledSourceNode.ended_event event.

Note: You can't create an AudioScheduledSourceNode object directly. Instead, use an interface which extends it, such as AudioBufferSourceNode, OscillatorNode or ConstantSourceNode.

Unless stated otherwise, nodes based upon AudioScheduledSourceNode output silence when not playing (that is, before start() is called and after stop() is called). Silence is represented, as always, by a stream of samples with the value zero (0).

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

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.

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.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
