Send Data Securely Using Audio

LISNR® is an advanced, near-ultrasonic, ultra-low power data transmission technology that enables fast, reliable, and secure communication between devices via any speaker and/or microphone.

Acting as a secure local proxy for data transmission, our technology is removing the need for complex, expensive, and power-consuming RF or other audio based technologies.

Why Sound?

Software vs. Hardware

Software vs. Hardware

LISNR is a software solution that can be implemented and executed across all operating systems and devices, allowing for advantages in cross-device flexibility.



The limits of detection range between devices are a product of audio type, amplitude/volume, and power. Sound surpasses the physical limitations of short-range radio based protocols.

Consumer Experience

Consumer Experience

Enables a seamless and consistent consumer experience, regardless of the operating system or manufacturer of the consumer's device.

Cost Advantages

Cost Advantages

LISNR can be transmitted using standard speakers and microphones across the entire ecosystem of sound. This bypasses the cost disadvantages of RF-based protocols.



Our technology can support industry standard security/encryption methods. You can locally generate tones on devices and send encrypted data creating secure communication between devices.


We use tone and data type optimization techniques to ensure a seamless and consistent connectivity experience for every operating system, device, or environment.

Low Power

LISNR® has proven itself to be the most battery and CPU efficient across the entire software spectrum, from the application level to embedded systems, with significant advantages in power optimization at the chipset level.


As out payload continues to increase - our current innovation, the KAB® (Kilo Audio Bit), has a maximum throughput of 1,000 bps.

Tone Profiles

We created tone profiles optimized for usage variables such as range (short/long), digital media compression (audible version), and payload to maintain reliability. All tone profile types are compatible with a single SDK.

Data Payload Types

We created optimized tone data types for use such as text (ASCII), ID, and binary data to maintain reliability. All tone data types are compatible with a single SDK.

Local Tone Generation

(Offline data transmission) This enables local data encoding and decoding for device-to-device communication without server connectivity.

Intellectual Property

Our proprietary technology has the best-in-class performance and the earliest global IP filing date for comparable data-over-audio solutions.
