I think we can rule that out as a possibility. Based on the Trump mic recording, and the delay of 0.218 seconds between the first shock wave and muzzle blast, a bullet fired from that far would have to have an average velocity of around 394 m/s. By the time it reached Trump it would be subsonic.
Gotcha, that sounds reasonable.
I don't mean to beat a dead horse but I'll submit below some info on sniper shooting that I found interesting. Just additional data to maybe consider.
Just out of curiosity, I looked up the longest sniper shots, and found the following image:
So, just in theory, and if we disregard the audio analyses, a shot from ca 700m should not be too much of a challenge for a pro.
Then, again out of curiosity, I checked if there are computer/AI systems that could help with the accuracy of shooting. My search produced several hits but suprisingly, the followin article is from over ten years ago, 2013. One can just imagine how much such systems have developed since then.
A new computer-aiming system for rifles lets you "tag" a target with a laser pulse and works out the best moment to pull the trigger, making life easier for long-range killers

Just weeks after the firing of the world’s first 3D printed handgun, a smart rifle that allows the user to accurately hit targets up to 900 metres away has gone on sale in the US. [...]
The PGF lets the user choose a target in the rifle’s sights while
the weapon decides when it is the best time to shoot – compensating for factors like wind speed, arm shake, recoil, air temperature, humidity and the bullet’s drop due to gravity, all of which can affect accuracy. To do this, the PGF’s tracking system includes a computer running the open-source Linux operating system, a laser rangefinder, a camera and a high-resolution colour display in an integrated sighting scope mounted on top of the weapon. The user simply takes aim and presses a button near the trigger when a dot from the laser illuminates the target.
The computer then runs an algorithm using image-processing routines to keep track of the target as it moves, keeping the laser dot “painted” on the same point. At the same time, the algorithm increases the pressure required to pull the trigger, only reducing it when the gun’s crosshairs are right over the laser dot – and the bullet is then fired. The gun is novel at another level: it has Wi-Fi.
This allows imagery from the sight to be streamed to a smartphone or tablet, so the user can share what they are seeing with others. In addition, it lets the user key a PIN into a smartphone to activate the guided aiming.
In tests, the system has proven astonishingly accurate – even with novices – at hitting targets at a range of 500 to 900 metres.

So, just in theory, using a computer/AI assisted aiming system it would be possible for even a novice to shoot quite accurately. Or, it could be used by a more pro shooter to increase the odds of hitting the target. I hope you don't mind my endless speculations
but if such a system would've been used in this incident – maybe the AI-system made a slight miscalculation?
