 		Register for this notification name with `[NSNotificationCenter defaultCenter]` or
-		`CFNotificationCenterGetLocalCenter()`. The "object" refers to an AUAudioUnit instance to
-		be observed, or can be nil to observe all instances. The notification's userInfo
-		dictionary contains a key, "audioUnit", an NSValue whose pointerValue is the
-		AudioUnit or AudioComponentInstance which is wrapping the AUAudioUnit communicating with the
-		extension process. (This may be null if there is no such component instance.) For example:
+		`CFNotificationCenterGetLocalCenter()`. The "object" refers to an AUAudioUnit instance
+		to be observed, or can be nil to observe all instances.
+
+		This notification can happen for several reasons, for instance the connection being
+		invalidated or the process abnormally ending. There can be multiple notifications for
+		the same event (i.e. a terminated process will also invalidate the connection).
+
+		The notification's userInfo dictionary may contain the following keys, depending on
+		the reason for the invalidation and the platform in which it's running:
+
+		@"audioUnit", a NSValue whose pointerValue is the AudioUnit or
+		AudioComponentInstance which is wrapping the AUAudioUnit communicating with
+		the extension process. (This may be null if there is no such component instance.).
+		For example:
 
 	```
-	[[NSNotificationCenter defaultCenter] addObserverForName:(NSString *)kAudioComponentInstanceInvalidationNotification object:nil queue:nil usingBlock:^(NSNotification *note) {
+	[[NSNotificationCenter defaultCenter]
+			addObserverForName:(NSString *)kAudioComponentInstanceInvalidationNotification
