    AudioNode.channelCountMode

    The channelCountMode property of the AudioNode interface represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.

    The possible values of channelCountMode and their meanings are:

    Value Description The following AudioNode children default to this value
    max The number of channels is equal to the maximum number of channels of all connections. In this case, channelCount is ignored and only up-mixing happens. GainNode, DelayNode, ScriptProcessorNode, ChannelSplitterNode, ChannelMergerNode, BiquadFilterNode, WaveShaperNode
    clamped-max The number of channels is equal to the maximum number of channels of all connections, clamped to the value of channelCount. PannerNode, ConvolverNode
    explicit The number of channels is defined by the value of channelCount. AudioDestinationNode, AnalyserNode, DynamicsCompressorNode

    Syntax

    var oscillator = audioCtx.createOscillator();
oscillator.channelCountMode = 'explicit';

    Value

    A enumerated value representing a channelCountMode.

    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);

oscillator.channelCountMode = 'explicit';
