Show HN: Cyrinx (36kbps Acoustic Transport)

ZH version is available. Content is displayed in original English for accuracy.

Working with Fable 5, a MacBook, and a Pixel phone, I built an acoustic transport library that is several orders of magnitude faster than existing SoTA open source options like ggwave, quiet, minimodem, or Chirp.

Really cool. I still miss the modem days... started at 2400 baud.

non working Play button makes me question anything else works, especially considering its LLMs all the way down from website down to paper and code

>Apache 2.0 source

LLMs dont hold copyrights

On licenses, what's your recommendation for best practice for an LLM co-authored project? Apache 2.0 or MIT seemed the best fit.

UPDATE: On the play button, I found your issue; I had tested on Chrome desktop and it worked fine, but I'm guessing you had Silent Mode enabled and I hadn't set the audio session to 'playback' from ambient. (You would have heard the sweep if you turned off Silent Mode.) I've now set playback mode and I have verified it now plays back just fine even in Silent Mode. You can verify it on cyrinx.org. Thank you for the bug report!
