== An Overview of the iPhone AVAudioRecorder Tutorial ==

The goal of this chapter is to create an iOS 4 iPhone application that will record and playback audio. It will do so by creating an instance of the AVAudioRecorder class and configuring it with a file to contain the audio and a range of settings dictating the quality and format of the audio. Playback of the recorded audio file will be performed using the AVAudioPlayer class which was covered in detail in the chapter entitled Playing Audio on an iPhone using AVAudioPlayer.
