AudioScheduledSourceNode class abstract

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

Properties

channelCount ↔ int
The channelCount property of the AudioNode represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.
getter/setter pairinherited
channelCountMode ↔ ChannelCountMode
The channelCountMode property of the AudioNode represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.
getter/setter pairinherited
channelInterpretation ↔ ChannelInterpretation
The channelInterpretation property of the AudioNode interface represents an enumerated value describing how input channels are mapped to output channels when the number of inputs/outputs is different. For example, this setting defines how a mono input will be up-mixed to a stereo or 5.1 channel output, or how a quad channel input will be down-mixed to a stereo or mono output.
getter/setter pairinherited
context → BaseAudioContext
The read-only context property of the AudioNode returns the associated BaseAudioContext, that is the object representing the processing graph the node is participating in.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
numberOfInputs → int
The numberOfInputs property of the AudioNode returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs property with a value of 0.
no setterinherited
numberOfOutputs → int
The numberOfOutputs property of the AudioNode returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.
no setterinherited
onended ↔ EventHandler
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

connect(AudioNode destinationNode, [int output, int input]) → AudioNode
The connect() method of the AudioNode 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). See also AudioNode.connectParam
inherited
connectParam(AudioParam destinationParam, [int output, int input]) → void
This is a variant of AudioNode.connect with a DestinationParam argument instead of an AudioNode. Note : The W3C recommandation uses just one verb for both.
inherited
disconnect([AudioNode destinationParamOrOutput, int output, int input]) → void
The disconnect() method of the AudioNode lets you disconnect one or more nodes from the node on which the method is called. See also AudioNode.disconnectParam
inherited
disconnectParam(AudioParam destinationParam, [int output, int input]) → void
This is a variant of AudioNode.disconnect with a DestinationParam argument instead of an AudioNode. Note : The W3C recommandation uses just one verb for both.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
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.

operator ==(Object other) → bool
