Is there an MT63 implementation in JS?

• qrdate

  6 36 0.0 TypeScript

  Trusted timestamps that you can physically include in photos, videos and live streams using QR codes and audible data signals.

  

I've been working on qrdate.org with some friends and have been discussing a way to sonify the signed string that we return from the web API, so that it could be played out loud for timestamping while recording video. The use case would be to blare the modulated output from a phone, radio or some other speaker while recording video with another phone, which would make faking the audio very hard due to natural convolution in the recording.

• mt63_wasm

  1 2 4.9 C++

Several years ago KD7BBC (hamstudy.org) wrote https://github.com/taxilian/mt63_wasm which I played around with (and helped out with, minorly). It seems to have build trouble these days, but that's probably fixable. It did work, and could interop with fldigi.
