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;
