My god... I just watched it in realtime... it's spooky. *shudders* It's a completely different experience to seeing it on a picture - trust me.
http://www.kempa.com/blog/archives/000083.html Link to download a trial spectral analyzer (needed to show the full thing, Audition only shows very little). Also has the wav file of "the face". Shows how lossy MP3 is, as the face is nonexistent in MP3 format. It's worth it! Download it!
It's short but it's spooky...
I can't imagine the person who first found this out and what their reaction would've been... *shudders*
I can't make them for shit. I tried making one simple one: "FUCKY" and all I got was: "F C". So I quit my audio imagery life.
IMPORTANT: Set frequencies to Log.
