In the space just before the "loopening", there's a sound, almost like a distorted fly sample. What's odd about it is that of the sample, it plays the second half first (the loud part) and then it plays the soft build up. I've glued both halves together and listened to it probably too many times (as well as reversed it, slowed it down, sped it up, played with its pitch, put it through spectro, etc) and it just keeps sounding like a fly buzzing. I just found it odd that it's two halves to the same sample.
Anyway, maybe someone else has other ideas about this.

EDIT: Also the gap after the first loop is pretty, pretty close to 0.1s in length exactly (when I first separated it, I got 0.099s). And the BPM is around 83.075 or so, as close as I could manually measure. I tried to see if it was close to (DEVIATION) 85.122 by some weird chance ... it wasn't unfortunately.
