AudioScheduledSourceNode
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2020.
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).
