title: Realtime microphone sound level monitoring
body: <p>I'm trying to access sound volume data from the microphone in realtime. I've tried AVAudioPlayer but it only monitors sounds from a source like an mp3 and not from a microphone. I've also tried The SpeakHere app but it's proving to be much tougher to understand with all the Objective C++ syntax (i'm a newbie). Is there another class similiar to the one in SpeakHere but written only in Objective C?</p>
