The International Ghost Hunters Society has been a pioneer and leader in the EVP development for the ghost hunting community since 1996. Today, many ghost clubs include EVP on their web sites. Electronic Voice Phenomena is a process whereby the voice or voices of the dead are embedded onto magnetic recording tape by a process that we do not understand. Some have success with digital recorders, but beware of digital static. Ghost voices are clear and do not sound like static.
Some voices are at the threshold of sound.
An appropriate place to begin recording Ghostly Voices would be old cemeteries at night The same protocol must be observed as for ghost photography in cemeteries. Any kind of tape recorder will work. The tape recorder should run for about 30 minutes. Any talking should be in normal voices. Some voices of the dead are very close to the background level of static.
