AudioNode.numberOfOutputs

The numberOfOutputs property of the AudioNode interface returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.

Syntax

var oscillator = audioCtx.createOscillator();
var outputs = oscillator.numberOfOutputs;

Value

An integer.

Example

var AudioContext = window.AudioContext || window.webkitAudioContext;

var audioCtx = new AudioContext();

var oscillator = audioCtx.createOscillator();
var gainNode = audioCtx.createGain();

oscillator.connect(gainNode);
gainNode.connect(audioCtx.destination);

var outputs = oscillator.numberOfOutputs;
