This is the notification article only, but well worth a short read.
and we will never see any credible data
because mr adams has no lab - he is just a grade 2 cockwomble
But just to measure lag time, no I don't think the microphones location is important.

Go to :50 in the video and hear him say it.

Can't see it. Don't care.
Adams is a snakeoil salesman who revels in clickbait. Always has been.

How do you determine originating shot vs echo to determine distance by time?
If you cannot separate originating shots from echoes, label the echoes, use the data as a base line to determine if the shots came from a different location, then analysis is useless. Sorry.

An echo of a shot is not noise. It’s the actual sound of the shot bounced off a surface to be heard again after the direction of travel changed. And it can be heard again for a third time if it bounces off the right surface to be heard a third time by the listener.

You think he has a very expensive laboratory?
Very...very expensive...like the most expensive... what other credentials do you need Phage?

If different people were firing, there will be different types of ammunition found, by clinicians and/or by site investigators. So let's see if anything turns up to support this claim.
Do you think that if different ammunition types are found, that they will tell us?

How possible is it, given the crowd present at the festival, that perhaps some of the crowd, in the confusion, drew their own guns and started shooting back? Scattering other shells and maybe even hitting other people caught up in the carnage by mistake?

It's possible.

I'm not 100% sure but, to me, it sounds like you're confusing a ricochet with an echo? A ricochet is when a physical object strikes a surface and it (or a part thereof) changes direction whereas an echo is when a sound bounces off something and changes direction. Sorry if I got it wrong but it sounded that way...

Didn't see this until page 5 lol...my bad. You don't need to model anything as all of that is secondary and inconsequential. What you would need to do is use the room as the position...then figure out how long it would take sound to travel to the approximate location of the microphone then compare it and see if the audio files match up. If they don't then you know it they were coming from somewhere else and that in itself is all the evidence needed to upset the OS. Just how I would approach it...I am not an expert or I'd make a hellova lot more money...but I am also much more knowledgeable than the average Joe about audio subjects in general.

No, I am not. Do you understand acoustics at all? An echo is the sound waves of the originating shot the changes direction after bouncing off solid surfaces. The sound wave will go down range. If it hits an object, the sound wave will change direction. It can be easily confused as a shot coming from a different direction. Why? Because it’s an actual sound wave of a shot bouncing around.
