E.V.P is short for Electronic Voice Phenomenon. This is what paranormal investigators believe to be a voice of a spirit. This voice or sound is not generally heard at the time of recording. It has been imprinted directly onto the recording medium. The recordings are evaluated using software such as Cool Edit Pro or Sound Forge.

A human voice is not capable of making a sound that is below 300 Hz. If a recording of someone speaking is obtained during an investigation and it is found to be below 300 Hz you can be sure that it was not made by a human.

Types of E.V.P's:

Class A - Loud & clear - interpreted the same by all listeners.
Class B - Reasonably clear - interpreted differently by some listeners.
Class C - Requiring headphones to distinguish the voices and open to individual interpretation.
