I started doing them in 2005, right after my father died from liver cancer. The very first one was pretty darn clear, and it said "Brittney" which is my name.
After that, it took a few weeks to get anything, then we started getting all KINDS of stuff!
The first one after that initial one, we put the recorder in my little girl's room, (she was a baby at that time), because there was a weird vibe in there. When we played it back later, you could hear my baby kind of getting fussy, then a woman saying "Don't worry my child, it was only a bad dream."
From then on, we got a SLEW of recordings, some comical, some scary, and we knew one in particular was a lady named Christine. We had it going one night, and I made a joke to my best friend Jennifer, that she had better watch the things she does, or Christine was going to get her. On the tape, right after that was said, there was a "I'm going to get you" on the tape.
Just wondering if anybody else does these recordings? I haven't done them in a while, and we've moved since then, but this place has strange happenings going on as well. We're thinking about starting some today.

I've never done one, but maybe i'll try one day, but not in my house. it would freak me out too much if i heard something.

EVP recordings, in my experience, are much like seeing Jesus in a piece of toast or a face on Mars: pareidolia (the perceptual phenomenon by which we perceive familiar patterns in disorder).
When I hear recordings, I never hear what the interpreter tells me I'm supposed to be hearing. I also think it's interesting that EVP messages nearly always come through in the language of the listener, regardless of the language of the purported speaker...

Here is some information from Skeptoid about Ghost Hunting Tools of the Trade and When People Talk Backwards, if you're interested in some other explanations of what you are hearing. Some of it is really fascinating, especially the "three-tone sinusoidal replica."

I do wonder what would happen if I took a recorder to a cemetery or the George Eastman House here in Rochester. Honestly, I've never done any myself -mostly because I've never heard one that inspired me to try it myself- but it could be interesting.

Actually just go to a hospital. That's where most people die. You should be able to pick up all kinds of voices of the dead. Either that or Security will throw a net over you and take you to the Special Ward. Strange happenings occur there in droves. With or without a recorder. But there you can record to your heart's content, and also there will be many other patients there who would make eminently suitable converts.
