Is AudioServicesDisposeSystemSoundID required?

Question

I recently started working with the AudioToolbox framework and noticed that there is a method called AudioServicesDisposeSystemSoundID().

Just to know, is it a memory leak not to call the above method when calling AudioServicesCreateSystemSoundID() to init my SystemSoundID? I am calling it like:

AudioServicesCreateSystemSoundID((CFURLRef)filePath, &sound);

That way filePath being a NSURL and sound SystemSoundID.

Yes. Call it when you're done with sound. Otherwise, you may leak any memory associated with sound (which can be significant for A/V files.)
