title: Current volume level of the Microphone input
body: <p>In my app I am recording voice using the microphone. I want to be able to implement some sort of visual indicator of the current volume level of the sound being taken in by the microphone. For example like in the Audio Recorder application for the iPhone which has a simulated analogue meter which moves to the right as the volume gets louder and to the left when the volume gets quieter. </p>
  
  <p>How can I get the current level of volume? I am recording the audio using an AudioRecorder object.</p>
