+          This is an <a><code>AudioNode</code></a> representing the final audio
+          destination for an <a href=
+          "#idl-def-OfflineAudioContext">OfflineAudioContext</a>. All rendered
+          audio will be routed to this node. There is only a single
+          OfflineAudioDestinationNode per <a href=
+          "#idl-def-OfflineAudioContext">OfflineAudioContext</a>, provided
+          through the <code>destination</code> attribute of an <a href=

+        </p>
+        <p>
+          An <code>OfflineAudioDestinationNode</code> is the equivalent of an
+          <a><code>AudioDestinationNode</code></a> for an <a href=
+          "#idl-def-OfflineAudioContext">OfflineAudioContext</a>. The output of
+          this node is produced by <a href="#SummingJunction">summing its
+          input</a> and captures the data that is returned by the <a href=
+          "#widl-OfflineAudioContext-startRendering-Promise-AudioBuffer">startRendering</a>
+          method.

+          The <a>channelCountMode</a> cannnot be changed. An error of type

+        </p>
+        <p>
+          The <a>channelCount</a> is set by the <code>numberOfChannels</code>
+          parameter to the <a><code>OfflineAudioContext</code></a> constructor.
+          After construction, the channel count cannot be changed. An error of
+          type NotSupportedError MUST be thrown on any attempt to change the
+          channel count.
