What are the two sources of the same sound?
Why don't the videos recorded in the city, close to the towers, have any explosions? Listen to this, very good audio - you can hear the tower collapsing. But no explosions.
This does NOT match the Hoboken audio - which suggests the Hoboken audio is recording some more localized noise.
On the contrary it does match exactly . . . Go to the 7:15 to 7:40 mark and replay the analysis . . . There were no explosive sounds recorded for many seconds before the collapse . . . Identical to the video you provided . . .
