    AudioBuffer.copyToChannel()

    The copyToChannel() method of the AudioBuffer interface copies the samples to the specified channel of the AudioBuffer, from the source array.

    Syntax

    myArrayBuffer.copyToChannel(source, channelNumber, startInChannel);

    Parameters

    source
    A Float32Array that the channel data will be copied from.
    channelNumber
    The channel number of the current AudioBuffer to copy the channel data to. If channelNumber is greater than or equal to AudioBuffer.numberOfChannels, an INDEX_SIZE_ERR will be thrown.
    startInChannel Optional
    An optional offset to copy the data to. If startInChannel is greater than AudioBuffer.length, an INDEX_SIZE_ERR will be thrown.

    Example

    var myArrayBuffer = audioCtx.createBuffer(2, frameCount, audioCtx.sampleRate);  
var anotherArray = new Float32Array;
// Copy channel data from second channel of myArrayBuffer.
myArrayBuffer.copyFromChannel(anotherArray,1,0);
// Copy data from anotherArray to first channel of myArrayBuffer. Both channels have the same data now.
myArrayBuffer.copyToChannel (anotherArray,0,0);
