How to filter background noise when recording audio using AVAudiorecorder in ios?

I am creating an application like Talking Tom . I can record and play it again using AVAudioplayer/recorder, but the voice is not clear, as background noises dominate.

Can someone tell me how to remove / filter the noise so that the recorded voice is clear.

For the most part, iOS does noise reduction internally, and I think it does it automatically.

The normal approach is to have two microphones, and then subtract the wave from the one that picks up the ambient noise from the one that envelops the user.
