LISNR is an ultrasonic inaudible technology; a communication protocol that sends data over audio. We use ultrasonic audio called Smart Tones™ to transmit information. LISNR transmits customizable packets of data every second that enable proximity data transmission, second-screen functionality, authentication and device to device connectivity on any enabled device. LISNR creates connections between devices previously thought too difficult or expensive to connect. Using the existing system of speakers and microphones, LISNR transfers data without the need for additional hardware like other communication protocols. We call it the Internet of Sound.
