Would be good to get him over here, to give his input.

Yes, people who know deep down inside that they are right, and have the evidence to show they are right, can get VERY upset when confronted with intentional liars and their obfuscating techniques.

Second - water transmitting the sound? Wtc buildings were in center
of Manhattan , about 1/2 mile from closest water. Don't you think
you are reaching?
"911 Raw The Research Edition" is the complete recording of the destruction of the North and South Towers. The sound is not enhanced, the video not altered. It is captured in its raw original data state and duplicated on this DVD as an encyclopedic work for research into the real causes of the three cement and steel skyscrapers destroyed in New York City that day.
"911 Raw The Research Edition" DVD Plus EXTRAS!
* Raw South and North Tower destruction recordings
* Raw Time-lapse of WTC 7 Implosion.
* Raw video from the night of September 11, 2001
* Raw video from the day of September 12, 2001
* Special Video interview with Richard A. Siegel
This is quite fascinating in my opinion. It’s a time lapse of Siegel’s footage with enhanced audio to emphasis the explosions.
Firstly, the recording has been sped up to approx 600%; this allows us to make new visual observations in terms of the progress of collapse. What is more revealing though is the audio. When you speed up the audio the very low bass frequencies that are often not picked up by laptop or low quality hi-fi speakers becomes audible, since your shifting the lower harmonics into a higher frequency range, although the sounds become shorter in length the audio details are still there.
Secondly, I filtered the audio dampening all frequencies above 200-300 Hz allowing for the bass (just the explosions) to pass through. You may notice people talking like chipmunks in the background which is the wins 10-10 News broadcast on fast forward.
Insolubrious: Anyone next to the site is going to be hearing much different things to anyone at Hoboken. Remember bass travels much further than treble or mid range frequencies. Also a standing low frequency wave takes a large distance to form correctly. Anyone at the site would be overwhelmed with mid to high range frequencies along with significant earth shaking and noise but may not notice the lower frequency things happening so much. At least to the untrained ear. Where as over at Hoboken the higher frequencies don't have enough energy to travel the distance but the bass certainly does, in fact it is an ideal location since there is a large open area of water to carry the sound and to allow the bass to form. Additionally sound travels further and faster through water because it is denser than air.
Insolubrious: North tower collapse is very interesting too, you can hear it coming, growing in amplitude long before the final big boom kicks in, almost like a reverse echo effect. There are two big swells then the big boom, then the collapse with a massive series of explosions. Very scary stuff. Sounds almost identical to WTC7 coming down.
One should also observe that the explosion(s) noise recorded here (LT: Hoboken!) in this clip would have been deafening across the river in Manhattan. There is no MSM footage which corresponds to the sound events recorded in sync with this clip. That is suspicious as evidence of a cover-up by itself. The MSM clips of the WTC1 and 2 collapses are muted at best and do not contain loud events just prior. These events must have been extremely loud for people near Ground Zero. Witness testimony does agree with the audio track as far as the general number (many) of explosions and the fact that they were loud. During the WTC1 and 2 fall sequencing the explosions up high may well have been less audible at street level. In addition, the demolition "wave" roughly progressed (accelerated) at 9.8m/S^2, thus very quickly the rate was on the order of milliseconds between detonations.
Insolubrious: found the approx. resonant frequency of the explosives and emphasized it (around 86hz it seems), then added a expander to change the dynamics of the amplitude (this makes loud sounds louder and quiet sounds quieter).
p.s the resonant frequency of the explosives may actually be a signature of the type explosive devices used and could contribute to identifying them. They are very low frequency and produce ground shaking which suggests extremely powerful type of explosives.
Insolubrious: As i mentioned I identified a particularly strong resonant frequency at around 86 Hz but a visual graph could also be generated to represent the audio. The majority of the blasts amplitude was sub 120 Hz. Some of which is expressed in ground shaking which is a very low frequency oscillation that pushes air pressure itself. But isn't necessarily audible, you just feel it and may even become disorientated by it.
