The Internet of Sound
has arrived.

Chirp is the world’s most trusted data-over-audio technology,
used by the leading brands in more than 90 countries.

Send data with sound.

Chirp uses sound to transfer information. Any device with a speaker or microphone can now send and receive data.

And, for small pieces of data, no network connection is required.

Application areas include one-to-many sharing, location-based offers, retail POS and Two-Factor Authentication (2FA).

We offer a set of general-use, standardised products as well as a programme for creating protocols which are optimised for specific use cases and bespoke to our partner's requirements.

Chirp lets you create sonic links of any kind. Anything you can think of is chirpable. How about media, like pictures, MP3s, text messages, or web pages? Or business objects like payment IDs, tickets, coupons, vouchers or redeemable tokens? Digital receipts? Business cards? Video clips? In-app commands? Chirp technology is in use in over 100 countries worldwide, making sharing as easy as one-button done.

People love to share

Mobile users expect to be able to share & interact between their devices. If your app doesn't let them send or receive now it can mean: lower uptake of your service, higher churn, lower sales, lower referral rates and poor retention.

Chirp lets you take advantage of real-world, person-to-person sharing, and it only takes a second for your users to share anything from passwords to pictures… and more.
