What is Data over Sound? | Chirp

Chirp sends and receives data using sound, with nothing but a device's existing speaker and microphone.

Information is converted to an audio signal, heard by nearby devices, and then converted back to the original data.

Chirp is a wireless communication technology for exchanging data over sound to nearby devices

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.
