Questions tagged [chirp]

Chirp is a wireless communication technology that enables devices to exchange data using sound.

Chirp enables apps to send and receive information using sound. A chirp encodes an array of bytes as an audio signal, which can be transmitted by any device with a speaker and received by any device with a microphone and Chirp SDKs. It is designed to be robust over distances of several metres, in noisy, everyday environments.

As the transmission takes place entirely via audio signals, no internet connection or prior pairing is required, and any device within hearing range can receive the data.

Chirps can be generated on-device from a dynamic data payload, or recorded as an audio file for later playback – like a sonic barcode.
