Also, I have listened to soooo many "evps" and well over 95% of the ones that I have heard can easily be dismissed as paradeolia. I like to call my wife and daughter into my office and let them "hear" the EVPs on youtube, ghsot hunters, ghost adventures etc, without letting them see the screen, they can alomst never get out of it what the "caption" wants you to hear.
Hey, did you read my latest comment on the other topic about EVP/ITC? I've outlined and explained a number of issues with this very "technology" that you're speaking about. Go check it! Should peak your interest my friend!
