Chirp, a pioneer of data-over-sound technology, and Arduino, the open-source electronics platform, have announced the first official integration of data-over-sound on Arduino’s range of boards. The integration allows Arduino-powered projects to send and receive data wirelessly through sound waves alone, using just microphones and loudspeakers.

The partnership between Chirp and Arduino aims to fully support developers when building projects that combine the companies’ technologies. This effort will provide developers with compatible libraries via the official Arduino Library Manager in Arduino Create, as well as the Desktop IDE, and further comprehensive documentation, tutorials and technical support, making it simple for anyone to build data-over-sound enabled hardware projects.


Chirp’s flagship data-over-sound solution enables the secure exchange of data between devices, using existing microphones and speakers. Data is encoded into a series of tones, played out over the air and decoded on the receiving device or group of devices. This way of embedding and extracting meaning from sound provides a quick, secure, and cost-effective solution that works completely offline, providing developers with a frictionless connection solution to send and receive data. 


“Sound is prevailing as a highly effective and versatile means of seamless data transmission, presenting developers with a simple to use, software-defined solution which can connect devices. Working with Arduino to extend the integration of data-over-sound across its impressive range of boards will not only increase the reach of Chirp’s technology, but provide many more developers with an accessible and easily integrated connectivity solution to help them drive their projects forward in all purposes and environments,” said James Nesfield, CEO of Chirp: “We can’t wait to see what the Arduino community builds.”
