    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;
