Chirp is like an audio QR code.

We send data seamlessly over sound waves to enhance end-user experiences and add value to existing hardware. It uses any existing speaker or microphone, and is configurable to use audible or inaudible near-ultrasonic frequencies.

Chirp is designed for simplicity, eliminating connectivity headaches and simplifying everyday tasks like connecting to Wi-Fi networks, sharing contact details, and making peer-to-peer payments.

Chirp technology is available as a suite of cross-platform enterprise-ready SDKs available to download for free.

Features

icon

Robust

Chirp’s software is robust to background noise and has been proven to work seamlessly in the most extreme environments.

icon

Easy to integrate

Chirp is a cross-platform SDK, which provides a fast and easy integration to a host of platform types.

icon

Low Power

In embedded applications, Chirp's power usage is lower than Bluetooth LE.

icon

Cross-platform

Chirp’s data-over-sound software is compatible with machines and devices of different platforms, form-factors, and architectures that can process audio.

icon

Works offline

Sound works completely peer-to-peer, or one-to-many, meaning no additional connections are needed to ‘the cloud’ or other network services.

icon

Uses existing hardware

Chirp’s software works with any device that has a pre-existing microphone and speaker, so there’s no need for additional hardware to utilise the solution.

Benefits

icon

Scalable

With Chirp’s software solution, there’s no need to think about reengineering as your application grows. Whether the aim is to enable seamless P2P exchanges or send data from one-to-many, Chirp’s software solution is completely scalable.

icon

Secure

Because Chirp’s acoustic connection does not require an internet connection and supports industry-standard cryptography, you’ll have peace of mind that any data transferred will not be compromised.

icon

Frictionless

Chirp makes simple, frictionless connections between nearby devices without requiring any set up, pairing, configuration, or the latest hardware or chipset versions.

icon

Cost-effective

Chirp is software only, and uses existing hardware - there’s no need for additional hardware to utilise the solution, saving you both money and resources that are better spent on your business operations.
