If you're interested in trying a little data passing in ultrasonic in your browser, try my creation https://quiet.github.io/quiet-js/ https://quiet.github.io/quiet-js/ This generally doesn't work in mobile, though, or at least reception doean't. Also, neither desktop nor mobile Safari can do mic access, and firefox's mic won't pick up ultrasonic. So try desktop Chrome :)
