Chirpr APPLICATION description
Radio-free acoustic-link messenger - send messages to nearby friends using sound
Chirpr is a radio-free acoustic-link messenger. Instead of using radio such as wi-fi, bluetooth or cell network it uses the device's speaker and microphone to transmit your message using acoustic chirps.
You can send text-based messages to nearby friends using sound.
This is a demonstration of how acoustic modems operate. Note, there is no encryption or security associated with this system at present. It is a simple message broadcast system that encodes a textual message into chirps which are then played through the speaker.
Chirpr uses Binary Orthogonal Keying (BOK) and Chirp Spread Spectrum (CSS) which translates to using up and down linear chirps to transfer information.
Any suggestions or problems please email me at [email protected] and let me know.
