Sound QR codes

UK-based app Chirp is also aiming to turn sound into a vehicle for data transmission. Users begin by selecting a URL or uploading a file they would like to send to another smartphone owner. The app then converts the link into a series of 20 short notes – known as a chirp. When others have the app running, the phone ‘listens’ to the chirp and displays a link to download the content being sent. The app is able to distinguish the chirp from background noise even in loud environments, making it suitable both for friend-to-friend sharing at home, for companies wanting to transmit data over a PA system, or for advertisers broadcasting on the radio, for example. Once the chirp has been received, the recipient can then choose to share it over social networks within the app.
