According to the patent, spotted by Metro, the system would use 'a non-human hearable digital sound' to activate your phone's microphone.

This noise, which could be a sound so high-pitched that humans cannot hear it, would contain a 'machine recognisable' set of Morse code-style beeps

Once your phone hears the trigger, it would begin to record 'ambient noise' in your home, such as the sound of your air conditioning unit, plumbing noises from your pipes and even your movements from one room to another.

Your phone would even listen in on 'distant human speech' and 'creaks from thermal contraction', according to the patent.

TV advertisers would use this data to determine whether you had muted your TV or moved to a different room when their promotional clip played.

  Next up, a little box that lights up when the signal is detected so you know when to put the phone in your back pocket and fart.

  That's dumb. The effort of embedding the circuit in the phone cover and make it "fart" for me when the signal is detected is trivial.
