<p>Measure the volume of a local media stream using WebAudio.</p>

<p>The 'instant' volume changes approximately every 50ms; the 'slow' volume approximates the average volume over about a second.</p>
<p>Note that you will not hear your own voice; use the <a href="../audio">local audio rendering demo</a> for that.</p>
<p>The <code>audioContext</code>, <code>stream</code> and <code>soundMeter</code> variables are in global scope, so you can inspect them from the console.</p>
