You may have seen the crazy video where Colsto was able to geolocate from plane Doppler traces found in the audio of a brief video clip. (It's incredible. Link below.)
Colsto hasn't released the source code, so I asked Claude Code to create a synthetic version to test the premise. The app generates a fictional audio clip with two Doppler traces, auto-fits them to determine each plane's speed and closest distance, then matches them vs fictional flights in a bounded area. No real data is used.
The method works remarkably well with the synthesized data (in "real tracks" mode, found the spot in 161 of 162 scenarios). Check it out!
Bonus: the code couldn't properly auto-fit scenario 98, but it's possible to manually fit the Event 1 curve and get it to match. Fun puzzle if you're up to it.
Built with WildflowerJS, using Claude Code and Opus 5.5.
