How the Ghost Box
Back to: Ghost Box
boxes work by what is known as sweeping of the FM or AM
As the channels are scrolled through upward or downward, a mix of white noise and audio fragments can be audibly heard. These audio fragments may best
be described as bits and pieces of disc jockey voices, music, or whatever
is being broadcasted across the band at the time the sweep is made.
With the ghost box
radio sweep method, the spirit or ghost voices seem to be
carried upon these audio fragments and white noise. We believe these audio
fragments sometimes not only alter the tone and overall pitch of the spirit
voice recorded, but also may affect the pace of the message making it line-up
in sync with the speed of the frequencies changing. While making ghost box
recordings, my own voice, while asking questions, will sometimes be altered by in pitch and pace, making it sound choppy and manipulated. For this reason, I do not believe that ghosts and spirits actually manipulate the audio fragments into forming words to create a message for us to hear. Many subscribe to this theory, but we believe it is incorrect. Our experiments seem to indicate that the spirit voices we record are affected by the frequency changes of the audio which is used as a carrier of the spirit voices.
have been times when we have also recorded spirit voices that
were not affected whatsover by the audio fragments and white noise, as pitch and tone were left unaltered by the sweeping ghost box. These messages seemed very much "on top" of the audio frags and white noise, but not affected in tonality, though they were syncopated in rythm, possibly caused by the frequency changes of the ghost box. These spirit voice recordings sounded much like EVP - Electronic Voice Phenomena , and were quite lengthy, appearing as the same voice in different recordings.
Sometimes the voices heard through the ghost box are altered by the sweep itself; but not always. This is why we cannot always know for sure whether we have recorded a male or female person on the other side of the grave by voice pitch alone.
