-		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.
+		Allows the user to record the sound from an audio bus. This can include all audio output by Godot when used on the "Master" audio bus.
+		Can be used (with an [AudioStreamMicrophone]) to record from a microphone.
