Eleven independent recordings. Eleven GPS-fixed positions. Every acoustic signature — Mach cone, stage detonation, muzzle blast, 4940Hz Strouhal tone — propagating across the actual UCCU Center courtyard at 343 m/s. Click any pin to see what that recorder heard, and when. Press play to watch the wavefronts arrive. Scroll to zoom, drag to pan.
Section 01 — Interactive Scene
All positions are derived from GPS coordinates verified to sub-meter precision (Google Earth KML). The tent (origin), the van, ten bystander camera positions, the Canon XA55 professional camcorder, and the rooftop firing position are all plotted on a true-scale local coordinate frame. Distances are in meters from the tent. North is up.
Section 02 — How to Read This
When a sound originates at a point and travels through still air, the wavefront is a sphere expanding at the speed of sound — about 343 meters per second at typical surface temperature. Seen from above, that's a circle. The instant the circle touches a microphone, that microphone records the arrival. The differences in arrival times between microphones (TDOA — time difference of arrival) are what allow the source location to be solved geometrically. This visualization runs that physics forward: it shows you the wavefront expanding from each known source, and the moment it crosses each known recorder. The arrival times shown in the pin info panels are computed directly from GPS distances — not measured, but predicted. The fact that those predictions match what was actually recorded across eleven independent devices is the basis of the entire forensic conclusion.
