So It's Back To First Principles (Part 2)

Hello,
I continued to study the audio analysis and found several posts by @offtheback that support my assumption that the first three bullets were fired from Building 9.

Audio Analysis Is Most Consistent Two Shooters At Trump Rally

Would the anomalies you found in the police car audio, if intentionally created, be suitable to cover up the sonic boom of bullets fired from the rear two-story building over Thomas Crooks? @offtheback Have you already analyzed the version of BWC2-122110 (Det. Collins trying to climb onto the roof)? Originally the sound only started after the shots at 18:12:08. In the new version, the sound can already be heard during the shots, but it sounds very muffled. [Compilation: Butler Tow…

I consider the following statement to be particularly relevant:

@offtheback

The echo has a higher-pitched peak frequency than the original shot. The long fat tail on the echo spectrum means that if this is real, the cruiser glass isn’t muffling the shots too much. But the report itself has almost no energy above 2000 Hz while the echo does.

The only physical world explanation that even starts to address this is that the echo is of the bullet sonic signature that bounced off something in front of the shot–I don’t know what that would be, DJ Stewart (joking)? Even he was too far away for that.

Can you refute his opinion?

I tried to find a way to confirm or refute my theory that the first three bullets were fired from Building 9. In doing so, I looked into the sonic boom. @vt1 claimed that my theory must be wrong because no sonic boom could be heard on the Ross/TMZ/Source 3 recording.

@vt1

Now your scenario is a gun fired from the back (in the small red circle) ahead in around 0.09sec before Crooks “fake” shot. For this scenario the gun used by crooks would have to be fired with a delay by some remote device. Then the gun from the back has a suppressed report represented in dashed black circle.

Now can you see the difference from the 2 scenarios? The Mach cone from a fire from behind (represented in yellow) is not suppressed like the report. Therefore, it will reach Ross audio before the “fake” report, keeping in mind that the crack from the first real scenario would not reach this audio. Since there is no audio of crack of the first bullet on Ross audio therefore this suppressed gun theory is not possible.

As I understand it, however, the Mach cone should look like this. Outside of this Mach cone, the sonic boom could not be heard, which is why my theory cannot be refuted by the fact that no sonic boom can be heard on the recording by Ross/TMZ/Source 3.

Do you agree?

@greg_n

Within the red area, the sonic boom could have been heard if the first three bullets were fired from Building 9.

Audio recordings from this area that include a sonic boom confirm my theory.

If the sonic boom were missing, my theory would be disproved.

Do you agree?
