    AudioNode.channelCount

    The channelCount property of the AudioNode interface represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.

    channelCount's usage and precise definition depend on the value of AudioNode.channelCountMode:

    • It is ignored if the channelCountMode value is max.
    • It is used as a maximum value if the channelCountMode value is clamped-max.
    • It is used as the exact value if the channelCountMode value is explicit.

    SyntaxEdit

    var oscillator = audioCtx.createOscillator();
var channels = oscillator.channelCount;

    ExampleEdit

    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);

oscillator.channelCount;

    ValueEdit

    An integer.
