A lot of the wild speculation regarding the bloop stemmed from the ultra low frequency audio being sped up 16x to be audible to the human ear.

  I was more fascinated by the original (http://www.youtube.com/watch?v=oCw16_Yxid0 http://www.youtube.com/watch?v=oCw16_Yxid0). Interesting part starts at 45s.

    Most of that sound is caused by artifacts of slowing the bloop down but keeping it in audible frequencies. Here's a more realistic version of the sound and a rationale of how it was made (needs a sub-woofer or some decent headphones to actually hear it): http://porkrind.org/missives/the-bloop/ http://porkrind.org/missives/the-bloop/

      huh. thanks. so i guess this is obvious, given the context, but that sounds like an earthquake (a decent sized one) feels, if you see what i mean... (also, you can hear it with decent speakers - no sub-woofer. it's audible with BW 602s (large monitors) for example)
