LISNR is the leading data-over-audio technology that utilizes sound and software to transmit data.

They use near-ultrasonic sound to transmit data using a speaker to and between any smart device with a microphone. A device enabled with LISNR® software can detect, transmit, and receive data from LISNR® audio technology within audio range. Once a LISNR® signal is detected, the SDK demodulates the data sent over the audio and performs the specified function on the device based on the data.

Lisner was introduced by Mercury Fund in 2020.
