Edit: If people want to send me links to all the angles available, I will try and do this analysis myself.
Overlaying the audio from different angles is a brilliant way to show the incongruity.
Theoretically, all gunshots (minus the counter snipers) should line up precisely in the audio waveform. As long as we are careful not to mix up echos and gunshots, they should be an exact match.
Any difference at all in the timing of the gunshots means that the sound had to travel a different distance in order to reach that specific recording device.
Using the known locations of each recording device, we can triangulate the position of each gunman by drawing circles with a radius proportional to the incongruity between the sounds in the different recordings, and seeing where those circles intersect. One should match Crook's known location. Where would the other one land?
I'm curious if anyone has done this exact analysis yet.
Can you do this with just one video?
As long as the mike is stationary, it should be fine.
No, in order to triangulate properly you would need an additional angle or two.
Some folks are using a crack-boom analysis on the podium mic feed, but that only gives you approximate distance to the shooter.
