Sound Radius Rings From Rooftop and Stage POVs

What This Image Shows
A satellite overlay of the UVU courtyard - the amphitheater plaza flanked by the angular campus buildings - with labelled pushpins and concentric colour-coded rings radiating out from each one. The rings are distance bands, drawn so that several candidate positions can be compared against each other at a glance.
The pins read Rooftop, Balcony POV, Stage Left POV, Charlie and Livestream POV, with Chick-fil-A marking a fixed landmark. Every one of those is a place a camera or a microphone actually was on the day, which is what makes the graphic useful: each recording captured the report from a known distance, so the arrival time of the sound on each track should differ in a predictable way.
That is the heart of the contested acoustic argument. Analysts working the released audio have argued that the report and the visible impact coincide too closely on the recordings for a shot fired from roughly 150 yards, and that a closer origin would fit better. Others hold that compression, frame rate and the limits of consumer audio make the comparison unreliable. This diagram is the map that argument is fought on.
