Changes

Since no audio has yet been recorded, the above method disables the play and stop buttons. It then identifies the application’s documents directory and constructs a URL to a file in that location named sound.caf. An NSDictionary object is then created containing the recording quality settings before an instance of the AVAudioRecorder class is created. Assuming no errors are encountered the audioRecorder instance is prepared to begin recording when requested to do so by the user.
