This is acoustic processing. The algorithms used need to be vetted. There are always artifacts from source noise, process noise, and echoes. This is only one acoustic sample---at what location relative to the sources? Other samples will be needed to exclude artifacts. In the end, it is a matter of the analyst's opinion, and it is seldom as accurate as a fingerprint. So...wait and see.
The most important takeaway from this video comes a few minutes in when he takes audio #1 and audio #2 and lines them up. Some of the shots do not match. Since the two recordings were made from different locations, this suggests that certain gunshots came from a different location. Supposedly the SS sniper didn't fire until later and shouldn't factor in here.
If they can find a recording from a third known location we could pinpoint a location assuming we know the location of the other two. We have one, the mic on the stage.
Yes. I managed to see the presentation by Dr. Masterson (?). Seemed pretty level headed. I would quibble with some points. The establishing oblique shot of the venue seemed to represent the shooting location as being on a lower ground elevation, based on extending the perspective lines from the bleacher seats. And it is not unusual for some .223 bullets to fragment upon striking a resistant object...or it may simply have spalled some paint off the railing that it hit. More details to be sorted out.
Have a listen of the main video of the shooting. You can hear that the sounds of the guns are quite distinct. No echo on second set, sounds like a different weapon.

Dude know his shit though!
This guy does indeed until proven otherwise...
Yes. I finally was able to see the analysis. Not overblown.

Triangulation...
And from what I heard, the SS sniper only fired 1 time, and it was the last shot fired, which he doesn't really include with his analysis.

funny how they don't have a shotspotter system set up at rallies

This is new to me... interesting!
Wait and see on every aspect, meanwhile dig, dig, dig...

Don't need special algorithms.
I've listened to the two recordings used by one scientific expert. Really hard to make out. It is not something that ears can determine.
