Detecting blowing on the iPhone microphone?
<p>I am trying to detect when the user is blowing into the mic of an iPhone. Right now I am using the SCListener class from <a href="http://stephencelis.com/2009/03/02/now-i-just-need-an-audience.html" rel="nofollow">Stephen Celis</a> to call</p>

<pre><code>if ([[SCListener sharedListener] peakPower] &gt; 0.99)
</code></pre>

<p>in an NSTimer. However, this returns true sometimes when I'm not blowing. Anyone have any sample code to check if the user is blowing into the mic?</p>
