Researchers Use Airplane Sounds to Geolocate Videos

Researchers have discovered a clever way to pinpoint the location of a video using the sound of a passing airplane, converting the Doppler-shifted hum into a motion trail that can be matched with flight data to reveal the recording's secret location. By harnessing the Doppler effect, which changes the frequency of sound as its source moves, they can turn a faint airplane rumble into a precise geolocation lead.
