Thanks for posting this - I'm the author. I recently posted this to Show HN with a bit of background about the project [0]. My next goals for ggwave is to improve the mobile SDKs and provide more examples. If you want to help out - check out this issue [1]. I am also planning to add some even lower bit-rate protocols, but make them more robust and hopefully remove the sound markers. - [0] https://news.ycombinator.com/item?id=25761016 https://news.ycombinator.com/item?id=25761016 - [1] https://github.com/ggerganov/ggwave/issues/2 https://github.com/ggerganov/ggwave/issues/2

Have you looked at other types of modulation? Like spread-spectrum: https://en.wikipedia.org/wiki/Spread_spectrum https://en.wikipedia.org/wiki/Spread_spectrum This would potentially give many nice features including superimposing multiple signals, so you can have full-duplex and more people can use the audio channel at the same time.

  Looks interesting. I haven't tried other fundamentally different approaches different than the one I am currently using. I only recently found that my approach is very similar to DTMF, but I use 6 tones instead of 2 and I have sound markers and error correction integrated in the protocol.

Fountain codes?
