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 audio fingerprinting based technologies.
LISNR is software solution that can be implemented and executed across all operating systems and devices, allowing for advantages in cross-device flexibility.
The limits of range between devices are a product of audio type, amplitude/volume, and power. Sound bypasses the physical limitations of short range radio based protocols.
Enables a seamless and consistent consumer experience, regardless of the operating system or manufacturer of the consumer's device.
LISNR can be transmitted using standard speakers and microphones across the entire ecosystem of sound. This bypassing cost disadvantages of radio based protocols.
Our technology can support industry standard security/encryption methods. Our header has additional encrypted security logic to bypass replay and phishing attacks.
We use tone and data type optimization techniques to ensure a seamless and consistent connectivity experience for every operating system, device, or environment.
We outperform other communications protocols, including RF-based connectivity or audio fingerprinting, particularly in the area of power consumption.
Our payload continues to increase - our current innovation, the KAB® (Kilo Audio Bit), has maximum payload of 1,000/bps (10X more than closest competitor).
Optimized tone profiles are available for uses such as range (short/long), digital media compression (audible version), and data payload to ensure reliability.
Optimized tone data types are available for text (ASCII), ID, and data (binary) to maintain reliability. All tone data types are compatible with a single SDK.
(Offline data transmission) This enables local data encoding and encoding for device-to-device communication without server connectivity.
Our proprietary technology has the best-in-class performance and the earliest global IP filing date for comparable data-over-audio solutions
