EVP stands for electronic voice phenomenon and is when ghost hunters use a small hand held digital recorder and will sit in a quiet haunted location and ask general questions. Sometimes you’ll hear a response but most of the time the spirits will answer in a frequency not of our realm. Later on the recording will be put on computer and run through a digital sound enhancer like goldwave where sounds on other frequencies will be identified. I was recently on an investigation where the ghost seekers were asking questions and we picked up an EVP that said repeatedly “get out! get out!” If you watch Ghost Hunters and Ghost Adventures, you’ll see that EVP’s are the best evidence gleaned on a paranormal investigation. It’s very easy to do so try it at your home sometime. Just be careful what you ask for you might get an answer you’re not expecting.
