EVP is a very common term in the ghost hunting industry. If you are not a paranormal investigator, but have watched shows like Ghost Hunters or Paranormal State, I'm sure that you are familiar with the term as well. I'm also sure that there are some that still aren't entirely sure what EVP is.

EVP or Electronic Voice Phemomena is an event where the disembodied voice of a spirit is thought to be recorded amongst radio station noise and other electronic media. They are most often recorded using an audiotape recorder.

EVPs are never detected while the actual recording is taking place. Only when playing the tape back do you have a chance of catching something interesting.  Some EVP's are clear as day and very easily understood, while others may have to be amplified and filtered to hear these voices. Most EVP's are one word, short sentences or grunts and moans depending on the strength of the spirit that may have been trying to communicate with you.

There are three different levels of EVP recordings that I am going to discuss right now.

A Class A recording is the loudest and clearest of the three different EVP types. This type is very distinct amongst the static noise, and very easily understandable.

A Class B EVP is the most common type of EVP. These are usually characterized by warping of the voice in certain syllables. Lower in volume or more distant sounding than Class A.

A Class C EVP is the most difficult to understand out of the three different types. This type of recording is the lowest and volume and is characterized by excessive warping.

One of the most interesting things about recording EVP's is the fact that sometimes it seems that the spirit you are trying to communicate with is answering your questions directly. Remember, however, that you will not hear any responses until you play the recording back.
