Audio recording with timer
<p>I want to take a photo and as soon as i do that, the audio should start recording automatically for say, 3 seconds.</p>

<p>Those 3 seconds should be counted down by a <strong>timer</strong> which appears on the left side of the screen, after the photo is taken. </p>

<p>So, then i have to <strong>combine the image and audio together</strong> and save it in a <strong>private directory</strong>.</p>

<p>Could someone tell me how do i do this by using the <strong>AVFoundation</strong> and <strong>Audio Toolbox</strong> frameworks?</p>
