Also, another. This one has our actual datastream on the audio track instead of CCR. You know that scene in Contact where Jodi Foster is listening to the radio telescope signal on headphones? It's kind of like that. We listen.

Has a real nice, peaceful "ring" to it! Is that sort of by design, kind of like choosing nice colors to make your graph pretty? Or is gravity just so.... very.... peaceful? Celestial, even.

What you're hearing is actually all noise (i.e. non-gravitational-wave signals)... I think whomever made the video played with the spectrum equalizer to make the tones a little more soothing. (-:

Ideally the noise spectrum would be completely white/gaussian with a just a few resonances. These videos are from a time when we were increasing the laser power and the machine's operation was less stationary than usual.
