No, that's the sound of one gun. You have to have 8 going at once,
something you can try to do with audio mixing tools, but it will
never be quite the same as the real thing. The thing is, 8 guns
ripping out of phase to each other are going to make a sound which
is necessarily less subjectively loud than a single gun, simply because
of the mechanics of the density patterns generated in the air,
and the way our perception of sound works, especially recorded sounds.
A lot of the subjective cues for loudness get washed out by too
much sound.
If you've ever worked in a very loud industrial environment, you'll
know what I mean. A fairly low energy region with a few widely
distributed machines banging away sounds very loud, though you
can manage to talk over/between the noise. The loudest room I was
ever in was a paper machine with a roll about 35ft across, with
the paper travelling such that it was winding up on a 1.5m diameter
roll at around 1200rpm. The white noise was such that the room
seemed almost silent, just a big whoosh, only you could yell at the
top of your lungs and barely hear your own voice. Vocal communication
was completely impossible.
