Here is a link regarding the sound captured on private video. It’s not what I saw the other day but it’s on the same track and uses the same recording. It does indeed have more analysis done that the one I originally mentioned.

For JFK, there wasn't a lot of evidence to contradict the 3-letter agency's narrative of a lone gunman. For the Las Vegas shooter, everyone's phone was confiscated, so the 3-letter agency narrative is hard to refute. For the attempted assassination of Trump, evidence is scattered, but not sequestered. The "official report" will take years, not 60 days as Cheatle said, because they have to be able to twist the facts on any scattered evidence that may surface to fit their narrative. They may never issue a real report.
The audio analysis I saw a video of was said to be the NBC feed from the stage microphone. It was a good analysis but needed additional work as I previously mentioned. Your link is good too, but there as well a more rigorous breakdown is needed.
Some naysayers are shouting SHOW ME THE MATH. I think it WILL be shown, eventually, but I'm sure at that point those same naysayers will find something else to demand. One twist I've heard is the "lone" gunman in Trump's case had at least two different types of bullets in his clip, the later ones with more gunpowder and therefor a higher velocity, and that accounts for the sonic-crack::muzzle report time-span difference when comparing the first three shots (.22 sec. IIRC) to the 5 to 6 shot burst (~.4 sec IIRC) that followed, and not due to a different distance between the stage microphone and two different shooters. I think that can be disproven by comparing two different recordings, but I'm not sure.
Interesting times we live in.
