AudioScheduledSourceNode
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 start()
and stop()
methods, as well as the ended
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).
Instance properties
