Chirp is a wireless communication technology for exchanging data between nearby devices via sound.

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. It's trusted by companies and developers across the world, from nuclear power stations to children's toys.

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