title: How to filter background noise while recording audio using AVAudiorecorder in ios?
body: <p>I'm creating an app something like <strong>Talking Tom</strong>. I can record and play it again using <code>AVAudioplayer/recorder</code> but voice is not clear as background noises are dominating.</p>
  
  <p>Can anyone please tell me how to remove/filter the noises so that recorded voice will be clear.</p>
