Recording and saving sound to file

Question

How to record sound and save to file (after that play it)? I need small-size file (as smaller is better) without reduction of bitrate. How can it be implemented on iPhone?

//Reduce or Compress the audio file size 1/4
[settings setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey];
