This (FSK + Reed Solomon for data over sound) is exactly what my team and I built at Chirp in 2012. We had some success as an app/SDK. If you Google around you can find some implementation details.
The hard/er stuff was making it nice for humans, robust to echo/noise, work in ultrasound, and functional on low-spec devices

I'm very glad to see people still thinking about it!
- tanepiper 3y agoI remember Chirp! It was a big influence for the work we did at the time for a project called "Add-on" which we tried to pitch to TV advertisers at the time. The idea was to embed sounds during ad-breaks that people could opt-in too. Didn't go anywhere, but our initial PoC code is still around https://github.com/pebblecode/adOn-soundlib https://github.com/pebblecode/adOn-soundlib
- moralestapia 3y agoFellow chirp-er here, we used it at school to chit chat in a group of friends. The fact that it was 'broadcasted' in some sense was an interesting dynamic. Thanks for the fun times!
