đŸ›Šī¸ Pinpoint a Location with Audio, Date, and Time

Colsto:

This video examines the amount of location information carried by inaudible background sounds, using the Doppler effect to locate a reference recording within ~100m, and only needing (in some cases) less 1-min of audio. This video raises awareness of these capabilities and closes by discussing preventative measures one could take.

They explain how they cross-reference public flight data with Doppler effect data to determine the location of a recording made anywhere in the US.

A fascinating and effective approach well-explained in just under half an hour.
