<script type="text/x-red" data-help-name="chatbot-audio"><p>The <code>Audio node</code> sends an audio to the chatbot from a local file or from a URL or from a Buffer passed by an upstream node (the simplest way to use it to chain with to <code>File node</code> or a <code>Http node</code>).</p>
<p>To programmatically send an audio with a <code>Function node</code></p>
<pre><code class="language-javascript">msg.payload.document = &#39;/my-file.mp3&#39;;return msg;
</code></pre>
<p>Or using a <code>Buffer</code></p>
<pre><code class="language-javascript">msg.payload.document = new Buffer(&lt;my-mp3-buffer&gt;);msg.payload.filename = &#39;my-file.pdf&#39;;return msg;
</code></pre>
<p>In case the upstream node pass through a <code>Buffer</code>, the node tries to extract a proper file name (visible to user in the chat client) using the payload of the upstream <code>File node</code> or the name of the node itself.</p>
<p>Available parameters for the <code>msg.payload</code></p>
