Revision 666133 of ChannelSplitterNode

<p>{{APIRef()}}</p>
<div>
 <p>The <code>ChannelSplitterNode</code> interface, often used in conjunction with its opposite, {{domxref("ChannelMergerNode")}}, separates the different channels of an audio source into a set of mono outputs. This is useful for accessing each channel separately, e.g. for performing channel mixing where gain must be separately controlled on each channel.</p>

<p>If your <code>ChannelSplitterNode</code> always has one single input, the amount of outputs is defined by a parameter on its constructor and the call to {{domxref("AudioContext.createChannelSplitter()")}}. In the case that no value is given, it will default to <code>6</code>. If there are less channels in the input than there are outputs, supernumerary outputs are silent.</p>
