1. A method comprising:
receiving, from a microphone coupled to a head-wearable apparatus, a first stream of inaudible sound waves in real-time;
generating a first binary representation of the first stream of inaudible sound waves, the first stream of inaudible sound waves generated by a first speaker source;
generating a first set of metadata based on the first binary representation;
generating a first plurality of augmented reality content items based on the first set of metadata;
causing display of the first plurality of augmented reality content items on a display device coupled to the head-wearable apparatus as the first stream of inaudible sound waves is being received;
receiving a second stream of inaudible sound waves in real-time generated by a second speaker source;
generating a second binary representation of the second stream of inaudible sound waves;
generating a second set of metadata based on the second binary representation;
generating a second plurality of augmented reality content items based on the second set of metadata; and
causing display of the second plurality of augmented reality content items on the display device coupled to the head-wearable apparatus as the second stream of inaudible sound waves is being received.
