 		Audio effect used for recording sound from a microphone.
 	</brief_description>
 	<description>
+		Allows the user to record sound from a microphone. It sets and gets the format in which the audio file will be recorded (8-bit, 16-bit, or compressed). It checks whether or not the recording is active, and if it is, records the sound. It then returns the recorded sample.
