YouTuber matches aircraft audio to ADS-B data to locate recordings
Colsto's method turns faint plane sounds into Doppler curves and cross-checks them against public flight-tracking data.
YouTuber Colsto has published a video demonstrating a technique that uses faint aircraft sounds captured in a recording to work out where that recording was made, Gizmodo reported. The method plots Doppler curves from passing aircraft detected in a spectrogram and compares them with public ADS-B flight-tracking data of the kind collected and published by the OpenSky Network.
In the demonstration, Colsto identified Doppler curves from two aircraft 920 seconds apart in a video filmed on September 8 somewhere in the continental USA. Matching those curves against ADS-B data cut about 70,000 candidate locations down to roughly 15,000.
Further details of the curves were then used to narrow the remaining candidates toward a single location, according to the video.
Earlier geolocation work
Colsto has previously made videos locating where album cover photos were shot, tracking down the location used by Primitive Technology and finding Andrew Tate's location.
Quick answers
How does the aircraft-audio geolocation method work?
It plots Doppler curves from passing aircraft picked up in a spectrogram of the recording and matches them against public ADS-B flight-tracking data.
How far did the demonstration narrow the search?
About 70,000 candidate locations were reduced to roughly 15,000, then further details of the curves were used to narrow the field toward a single location.
