"The assassins in Paddock's room gets[sic] a call"

"assassins"(plural)

That's some fantastic creative think there.

Only problem is it doesn't hold up in the reality of the audio - which only seems to show ONE murderer firing at any given time.

If you've got another example of audio you believe demonstrates multiple active shooters- I'd be happy to look at it.

An analysis of two sequential burts of gunfire between:

and
https://www.youtube.com/watch?v=mBbOFwWquAw&feature=youtu.be&t=1m24s

===============
T1: Time from start of video (1minute N seconds) at the time of the last shot in the burst.
T2: Time from the start of the video (1minute N seconds) at the time of the echoed sound event corresponding to T1.
TempF: the air temperature (72 degrees F)
FPS:   1130 ft per second -- The speed of sound at 72 degrees F
Elapsed Time:  T2 minus T1, the number of seconds between the last shot, and the echo of the last shot in each burst.
Total Distance:  Elapsed Time * FPS = the total distance traveled between T1 and T2.
Echo Distance  = The distance the echo traveled from the aiming point back to the point of origin.
===============

Conclusion:  Burst B is NOT two weapons being fired simultaneously.  It is one weapon being fired at a more distant target.  The longer distance, observable in the period between Burst B's T1 and T2, manifests a corresponding longer period of reverb.  It is the reverb that is being incorrectly interpreted as a second weapon (and second shooter) firing at the same time.

Many of the video's you can hear what you're calling Echo's and shots from the weapon. Sometimes the "echo's" come come in before the shots fired.

They also have a different firing count.

That isn't even logical. It can't be an echo.

On top of that the taxi driver when the video first starts you can hear shots and the echo. From that you can hear what the echo's sound like.

Here is an example of one video:

At 13:30 and 18:50 absolutely no doubt what so ever there were two shooters

One is far away(hotel) the second is very close (near parking lot)

You might want to back up the first time stamp a bit.
That way you can clearly make out the have no similar pattern.
