The forums data was imported as raw audio. A noise filter was then applied to that audio. The processed audio track was then duplicated. The duplicated track was reversed and inverted. The two tracks were then panned hard left and right.
The resulting stereo track was then Paulstretched.

Man, that's eerie. It reminds me of the "sounds" of various planets. Which is similarly spooky stuff. This means I'd use it in the same sort of context: creepy mood music for exploring some ancient or abandoned place in space, with some themes of madness and isolation.
That video of the sounds of Jupiter is one of my all-time favorite YouTube videos.
Helena, I'm not exactly sure what kind of processing NASA did on the planetary sounds but the recording I made started out just sounding like loud static. The noise filter brought out individual tones and then the Paulstretch changed it from sounding like a series of beeps to something actually eerie. So, it's a product of the forums data but mostly filtering in Audacity, to be perfectly honest. I think most random noise could produce a similar recording.
Jupiter (and most other planets) do produce actual radio frequency tones, however, and merely converting them to audio within the audible range is enough to produce... something. NASA may have filtered it a bit but I'm not sure.
Listening to that audio track you made through headphones gave me a really bad headache and I ended up getting sick tonight. I think it's probably a coincidence however but the headache started right when I started listening to it.
