How does Chirp work?

Chirp’s proprietary data-over-sound technology encodes data into a series of audible or inaudible, near-ultrasonic pitches and tones to form a ‘sonic barcode’.  Data is encoded on a sending device before being transmitted, over the air, to a receiving device, or group of devices where it is decoded.

Chirp also provide the ability for a receiving device or application to hear and react to pre-existing audio. This solution requires no additional audio data such as audible or inaudible signals to be transmitted and received, rather the original audio is processed by the software on the receiving end only.
