The most recent version of our tech, LISNR 5.0, contained a number of new product features and improvements to our Smart Tones that will make device-to-device connectivity and delivering memorable experiences easier than ever before.
We’re especially excited about Local Tone Generation, which enables device-to-device communication, bypassing the need for a separate network. Our tones can now be decoded and encoded directly from the device, so no additional connectivity is needed. This new feature opens the door for a wide variety of devices to interact with each other on a wide scale without other forms of connectivity.

Prior to this release, the customer’s app had to pass data to our server to be turned into a tone, downloaded from our server to the user’s device and then played back. We are taking all of the magic of creating a tone on a server and baking it into the mobile API, allowing significant flexibility and speed to build out the best user experiences possible.

For example, you can now use tones to safely and securely authenticate users for mobile payment, venue check-in and other use cases that may require some form of authentication. With LISNR Smart Tones, the information shared is secure and disappears as soon as the sound wave dissipates.

And it’s incredibly reliable, with 100% connectivity in multi-environment tests.

For example, we use this technology to enter our building. Anyone that visits gets a unique key that expires after they visit our office. No need for physical keys that get lost or stolen.


Smart Tones can also be used to power a POS system when used in tandem with an enabled app. A retail customer checks out without every needing her credit card.

You can also use the technology to securely send messages between devices, even in airplane mode.

LISNR is a high-frequency, inaudible technology, a new communication protocol that sends data over audio. As the leader in the Internet of Sound, we use inaudible sound waves called Smart Tones to transmit information. LISNR sends customizable packets of data every second, enabling proximity data transmission, second-screen functionality, authentication and device-to-device connectivity on any LISNR-enabled device. We enable this functionality reliably and more efficiently than Bluetooth (proximity), ACR (2nd Screen) and NFC/RFID (authentication). As an integrated software partner, LISNR powers devices to connect with the world better than ever before.
