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 onended event handler.

You can't create an AudioScheduledSourceNode object directly. Instead, use the interface which extends it, such as AudioBufferSourceNode , OscillatorNode ，和 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).

特性

继承来自其父级接口的特性， AudioNode .

方法

Inherits methods from its parent interface, AudioNode , and adds the following methods:

start()

Schedules the node to begin playing the constant sound at the specified time. If no time is specified, the node begins playing immediately.

stop()

Schedules the node to stop playing at the specified time. If no time is specified, the node stops playing at once.

事件

监听这些事件使用 addEventListener() 或通过把事件监听器赋值给 on eventname property of this interface:

ended

Fired when the source node has stopped playing, either because it's reached a predetermined stop time, the full duration of the audio has been performed, or because the entire buffer has been played.
Also available using the onended event handler property.
