title: Can AVAudioRecorder be used to record audio coming from your iOS app?
body: <p>I'd like to record the audio coming <strong>from</strong> my iPhone app. So after the background music and sound effects are mixed I'd like to sample the audio before it's played from the device's speakers (or headphones). </p>
  
  <p>I've been experimenting with <a href="http://developer.apple.com/library/ios/#documentation/MusicAudio/Conceptual/AudioUnitHostingGuide_iOS/Introduction/Introduction.html#//apple_ref/doc/uid/TP40009492-CH1-SW1" rel="nofollow">RemoteIO Audio Units</a>. These seem promising. However they're pretty low level. Can <code>AVAudioRecorder</code> (or other "high-level" object) be used to capture audio coming <strong>from</strong> an iOS device?</p>
