AUTISTS ASSEMBLE: Forensic Acoustic Analysis, Megathread 1

youtube.com/watch?v=JxmEFeKy8aI
Forensic acoustic analysis determined that there were two shooters in two separate locations*. In this thread, we use the same simple technique to triangulate the exact locations of the two shooters. The analysis is based on "lag time" signatures. This refers to the lag time between the sound of bullets hitting pavement and the sound of the muzzle report. This lag time is determined by the distance of the shooter and the type of ammo used. Two distinct lag times were found. This cannot be explained by use of different ammo, because the difference in lag time is too great, and the two shooters' fire overlaps at times. *This is NOT meant to imply there were ONLY two shooters/gunmen, but that the shots captured on audio seem to have come from two shooters.

THE PLAN:

1. Identify good (preferably free, open-source) audio-analysis programs for analyzing the audio.
2. Identify locations from which specific videos were recorded. (In order to use videos for acoustic triangulation, we must know their location with a decent degree of precision.)
3. Select videos with dispersed locations (this allows for the most effective triangulation). Only 3 videos are needed for triangulation, but 4 or 5 might produce even better results.
4. Analyze audio in each video to determine lag time of each shooter for a given video, and thereby determine camera/mic distance from shooters.
5. Draw two circles around each video location, the radius of each circle being the distance from the two respective shooters. The two places where three circles intersect are the locations of the shooters. (Note: wherever a circle overlaps a building, such as the Mandalay, elevation will have to be accounted for, but that is only another simple calculation.)

TALKING GUNS

Relevant. I can't say it's a 240 for sure, but the caliber and rate of fire is the same, which is common with a lot of eastern LMGs too, but considering all the gucci ARs around I'd bet it was a 240.

If two distinct lag times were found,

WHY DIDN'T HE FUCKING SHOW THEM IN THE VIDEO!!

It's Bullshit.

>this is what happens when you comment before finishing the relevant material to the thread.

What are you talking about?

Does anyone care to share any videos? They're hard to find for some fucking reason.

also fuck you again. You commented 10 minutes after the thread was made you didn't even finish watching the video.

It should be good enough. You just want to measure the time between certain points in the waveform.

Fucktard. I watched the entire video last night.

He doesn't show THE MOST CRITICAL PART OF HIS ANALYSIS.

Gio Rios video
was at concert
ran to Tropicana
oh shit gunfire here
run some more
go somewhere else
fuck more shooting at me
NY/NY - Excalibur area
youtube channel edited out some shit?
need original

The cadence of the bursts suggests one shooter inside the mandalay. Another shooter is possible but i would agree the location would be at the belagio for example. not from the windows because the periods without fire would in the deadliest scenario filled with the second guy.

You clearly didn't watch the video and/or you are a shill, I'm done entertaining you.
Watch it again if you want to save face, I'll hold my tongue.

supposed synching of multiple videos. get to work

youtube.com/watch?v=t2uEKUc0_Vc

Don't waste you're time. OP video is confirmed bullshit

No you clearly haven't watched the video. At no point does he ACTUALLY MEASURE LAG TIMES.

This could be gold, thanks upside-downanon.

Where's the evidence for the second shooter? Have we found bullet casings, powder burns, anything?

youtu.be/gdxYAW-Iawc

Gunshots are clearly coming from a distant location other than MB.

Guy pans camera trying to find the location of the shooter.

Machine gun fire not even as loud as the police sirens.

If the gunfire was coming from right below them it would have scared the shit out of those people. They remained calm.

The locations of the half circle buildings in relation to the camera show the person filming is at the MB.

vegas anons check the windows at the belagio or ask staff

Pretty good video. However one flaw in it is that calculations are performed using the characteristics of only one gun/bullet type. He did not consider that different weapons were allegedly used which have different time characteristics and therefor different sound arrival times at the same distance. However if the two weapon sounds overlap then it is valid proof (Unless Paddock fired two guns at the same time which seems very unlikely). And the sound arrival time difference of both sounds seems rather large for them to be fired from the same location.

Watch the video again and better luck next time

I've analyzed his 'forensics' video and he doesn't even understand the equation he used firstly. Secondly he doesn't show which peaks he used in the audio file. Its a bullshit video made for views, look at his youtube channel. Dudes a classic pseudo-science scammer

Dude, 'Forensic Acoustic Analysis' proved nothing but more questions from this wicked awesome analysis hand-written onto a white board. There are many assumptions that he makes without even realizing it, let me lay these out for you:
>temperature and humidity are constant
>no thermal updraft
>no lateral wind
>off the shelf ammunition being as consistent as hand loads
>all weapons used by Paddock are 5.55/223
>all weapons used by Paddock are 16" barrel length
>PADDOCK SHOT AT THE SAME EXACT LOCATION EVERY TIME
>the alleged second shooter being restricted to the same aforementioned assumptions

I want a second shooter, because it would red pill the fucking normies while watching the FBI burn. However, the video this dude made has more holes than a dead Paddock. You and the other autists need to rule out all assumptions and come up with as many constants as you can or you are left with a shit equation.

Someone who watches a lot of CNN and is mathematically illiterate generally comes off as a shill, which is really frustrating because it's become something of a witch hunt....
Generally the tactics are to spam the thread so anyone who's on the fence about the subject and isn't reading in depth to the posts or doing any calculations for themselves would see people nay saying and return to their NFL best tackles ever 2017 video.

OK, you gullible fuck. Give me the timestamps of where I should look in the video for the lag measurements.

this shit is tense af

Quick question about visual analysis as well, has anyone explained the missing "13" on the picture of dead Paddock?

Someone should get Schneier to do an analysis on this "conspiracy theory".

It's right up his alley anyways.

or the earlobes differences

You can hear two rifles in the video user.
On account of the amount of weaponry in the room, the witness accounts, and discrepancies in the evidence such as this video which does not correlate to what the FBI is saying, to believe the official story without question is asinine.

>Machine gun fire not even as loud as the police sirens.
interdasting, if any more gunfags can verify for a nogunfag. would be great ty

is that the illumanati

>Don't waste you're time. OP video is confirmed bullshit
Your image criticizes the person who made the video based on some websites he allegedly has. That reasoning is invalid.

You don't provide actual calculations showing that the microphone distance is relevant (lazy?). Strangely enough you put a lot of effort in your infograph (now not lazy?).

=> Fuck off unless you provide actual calculations.

i remember people were on this right away and then i stopped hearing about it

>13 doesn't show up in any other picture of Paddock
Wow its fucking nothing

Chest/Stomach wound being hidden? Pic related

>acoustic analysis shows two different shooting locations
>police & FBI reports showing the shooter used two guns in two rooms is NONSENSE

Nice detective work, anons. Let's ignore the obvious discrepancies and changes in the official story. That Campos guy doesn't merit any further investigation for sure. Just keep focusing on the "acoustics".

seriously do people think he had a 13 tattood right there? i fucking doubt that, though the earlobes is weird

also in the 4 man interview I can't remember maybe 60 minutes the cop mentions that the revolver was on the ground when they got there so speculation about police moving it is over until next press update/narrative change

>hurr durr we can't devote a thread to examining the acoustics, one of the single most important pieces of forensic evidence in confirming any other possible shooters

>REEEEEEEEE STOP OPPRESSING ME WITH CRITICISM

>ad hominem bullshit

>in order to derive distance, you need a precise target.

No, you don't. Otherwise, he would not have found TWO AND ONLY TWO DISTINCT LAG TIMES. Modest variations in target will not significantly affect lag time. In any video where bullets can be heard hitting pavement, it's safe to assume the camera is reasonably close to the bullet impacts.

>Adams doesn't show us the actual waveform data

So WHAT? We can look at it ourselves, which is what he asks us to do.

>assumed all same gun/caliber/didn't include drop

Bullet drop? That has nothing to do with this. Again, you're taking things that have only tiny effects and trying to use them to poke holes in the science. Furthermore, as I explained in OP, differing gun/caliber cannot explain such a big difference in lag time. Also, it is a simple thing to substitute the distance data for different ammo to see what result it brings. The bottom line is that the calculations can be done, and things that cause tiny variations are not relevant and are obvious shilling.

We have two rooms from where we can see a flash in the videos, we have one unaccounted chopper, and two shooting directions.

Thank you user. I don't have the energy to fight with shill/idiot types sometimes.

Underrated

already debunked, sorry drumpflets

urban, city people are to smart for you

Another thing that user's may be able to do with video footage is pinpoint with great spatial resolution the exact location of where the video was taken with a discrepancy of a few meters. Locate all of the cell phone towers AND repeaters in the Las Vegas valley. If there are three devices that are line-of-sight, then the location of where a video was taken can be confirmed- move to step two which is breaking down the audio for multiple shooters.

So few pics of him available though.
And the casinos have yet to release the footage of him that was undoubtedly taken through this several days there.

I already analyzed it and didn't find evidence you're talking about. This guy says supersonic cracks are "pavement hits"

Not going through this again, you can believe whatever you want.

>Ignoring what was said in OP about how the size of the difference in lag time cannot be explained by different gun/ammo, not to mention that those two rooms are very close to each other, so that can't explain it, either.

>Implying we can't both investigate Compos, etc, and examine acoustic evidence.

If they're shooting from inside a room, the sound of the gunfire would mostly come from the hole that is broken window. I assume the floors and walls have good sound insulation. Gunfire would probably penetrate a floor or couple of walls, but maybe not multiple floors.

>I think there was a 2d shooter
>forensic, science, technical analysis

To

BUMP
Watch the jewtube, this is a smoking gun. ((badum tish))

I like you user, you are as skeptical of both the "cumspiracy theories" as you are of the official story like I am.

It doesn't matter the barrel length or the exact accuracy of the constants such as humidity etc because he used the same calculation for the two seperate guns, meaning regardless of the exact accuracy we know that one was firing from further away because of the two different impacts, unless he was running back and forth 200m there was someone else with the same kind of gun.
I also doubt that was a 5.56 after all my experience with weapons in law enforcement.

>FBI niggers can't into spectrogram analysis
>Here's muh work
>Let's skip the evidence and jump right to my conclusions
>No comments allowed because I can't handle those bantz

What did this faggot mean by this?

One thing he missed is the possibility that the second guy used faster (or slower) bullets and thus be further (or closer) to the recording point.

Equivalent of the "Engineers for 9/11 truth", a big nothing designed to suck in people forever. You guys will never prove anything and will go one discussing this forever, meanwhile the truth that everything is a hoax and pure media theater will get buried.

tl;dr the shooting sound was fake and broadcast on PA, dimweeds. It is self-contradictory because this is how psyops are designed.

How big of a difference does 3200 feet per secoond make compared to 2800 feet per second?

here's another analysis
at 9:38 in video are two 3 round bursts or a 3 round then 4 round burst
theres a video from concert goer where you can hear this

hooktube.com/watch?v=_kdsitqiWoE

Regardless that would mean a second shooter, or paddock went akimbo with super fast bullets that no one has ever seen before

>you don't get a whole hellova lot faster than a 5.56

>It's a hoax because I say so

there are dozens and dozens of videos on youtube showing audio analysis of several video you fucking moron.

you guys familiar with echoes?

Well yeah you are probably right as im not the most knowledgeable person when it comes to guns (let alone ballistics)

I suppose a picture like this one makes sense to you, because it shows "heroic police" and the media tell you so. Forget about the extras hanging around while the fake police actors take cover.

LVMPD released at least SOME body worn cam footage.
there must be more

>pointing away from supposed source of gunfire

Cute

Show me just one.

???? this is nothing even close to a proper/complete analysis
he was recessed

what a worthless, pathetic, lazy, faggot you are.

bump for Illuminati confirmation

I can’t get passed the glove on his hand. Nobody would wear those old man gardener gloves while shooting any weapon with picatinny rails or mags they needed good grip on. The cotton fabric would catch on the sharp angles of the rails and the mags would slip out of the glove due to a lack of grip. Those gloves would cause many many problems.

...

“past” not passed

No, I've watched all the videos out there, but you can't post a single link or time stamp.

im all for a good conspiracy theory but im curious as to what you guys think the reason this would be staged? who benefits from this? and what do they benefit?

That one was reasonably interesting.

The metal detectors companies for sure.

you guys dont think the dude was up there with what? 16 guns duel wielding that shit? i still dont see why they would hide the fact that there is 2 shooters.

fucking stupid

hey guys
this fucking Campos guy (pronounced COMP-os)
it's a stick in our eye
They comp'd us

Checked, had anyone looked into this? Security guard jealous of the comps??

Quite a lot. Especially if the speed decay is non-linear.
