Here is a spectrograph of this bizarre sound:
747 Jet engine full throttle, same program, same track, so exact same plugin and everything:
A few things to keep in mind:
1) Very bottom is 35 hz
2) Notice what appears to be harmonic bands
3) Her camera likely could not pickup below 20 Hz, if that, and more likely 30 or 40 Hz on the low end
4) And that's what makes this even more bizarre. Had you been there, there was likely frequencies going way down to be shaking the house, and those
are neither present in the wav file or in the spectrograph. The mic in the camera simply cannot respond to frequencies that low, so that must have
been absolutely terrifying.
5) I'm stumped. Unless that was the most massive harmonic tremor ever, and Florida is getting ready to erupt with a supervolcano...
