I am referring to the laws specifically. California's law specifically states that a beep is sufficient to establish recording notification, so that one is out; Florida's law requires intention; as do Illinois, Maryland, Massachusetts, New Hampshire, and Pennsylvania. Washington is the only state where it isn't totally 100% clear, and the law seems to read that a tone would be sufficient to establish consent.
