This isn't actually a case of pareidolia, as the squiggly noises (they call it "sine wave speech") are in fact derived from the middle recording, using an effect that sounds, to me, most like an extremely low bitrate mp3 encoding. Reading up on how they produce the effect, it is in fact a very similar process to mp3 encoding. (Perhaps inspired by it? I believe most general audio codecs work on very similar basic principles.)

So it's the opposite of pareidolia. It's actually meaningful sound, but it looks random at first. Maybe we should call it ailodierap.

True; I suppose it's a demonstration of the thing that makes pareidolia possible -- the should-be-obvious-but-isn't fact that pattern recognition takes place in the mind.
