<dl>
<dt><em>channelCount</em> {{optional_inline}}</dt>
<dd>Represents an integer used to determine how many channels are used when <a href="/en-US/docs/Web/API/Web_Audio_API/Basic_concepts_behind_Web_Audio_API#Up-mixing_and_down-mixing">up-mixing and down-mixing</a> connections to any inputs to the node. (See {{domxref("AudioNode.channelCount")}} for more information.) Its usage and precise definition depend on the value of {{domxref("AudioNodeOptions.channelCountMode")}}.</dd>
<dt><em>channelCount</em>Mode {{optional_inline}}</dt>
<dd>Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs. (See {{domxref("AudioNode.channelCountMode")}} for more information including default values.)</dd>
<dt><em>channelInterpretation</em> {{optional_inline}}</dt>
<dd>Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio <a href="/en-US/docs/Web/API/Web_Audio_API/Basic_concepts_behind_Web_Audio_API#Up-mixing_and_down-mixing">up-mixing and down-mixing</a> will happen.<br>
The possible values are <code>"speakers"</code> or <code>"discrete"</code>. (See {{domxref("AudioNode.channelCountMode")}} for more information including default values.)</dd>
