Heya Rick, thanks for the useful info!
I had an idea... Has anyone tried using PZMs? I've heard that most EVPs are caught in the lower and higher frequencies, and if so I think a PZM would be much more suited for picking up those higher frequency "voices". Also mics that CAN pick up outside the human audible range would be better suited for this.
Also, has anyone had any luck slowing down/speeding up the playback to see if anything is there out of phase?
And thirdly, (this is a wild one!) is there anyone out there with a homemade Van de Graff generator or has access to one? If so, try doing an EVP session near the generator while it's charged up. I don't have one so I can't do the experiment myself.
God, I can think of all kinds of experiments to do with this stuff. Here's another... Power your recorder externally, (AC outlet). Connect the mic but allow the signal cord to cross the power cord, perpendicular. I know you'll get interference, maybe 60 cycle, but I wonder what would be picked up in between?
Just a few ideas.
