SJGR: Electronic Voice Phenomenon training information
Electronic Voice Phenomenon is one of the best pieces of evidence
we can obtain on an investigation. It is much harder to
dispute this evidence especially when the EVP is found to be out the
range that could be made by human vocal cords (300 – 3000 Hz) although
many great EVPs do fall within this range. The EVPs can also
potentially help us figure out the nature of the spirit, the identity
and more. Because there is so much more value put
into a good clear EVP than an orb photo or even an EMF reading, we
should take the time to attempt to record some on every
case. Investigations with digital voice
recorders can easily do audio recording on a case with no set up time
so there are few reasons why those member shouldn’t do this on every
case.
History of EVPs
Thomas Edison said in the October 1920 issue of Scientific American
that he was working on was working on an EVP recording device. However
the credit for discovering EVP goes to Fredrich Jurgenson when in 1959
he was recording bird songs in the Swedish countryside and on play back
he distinctly heard the voice of a man discussing nocturnal bird songs
in Norwegian. He had heard nothing during the recording but many voices
on playback, some giving him instructions on how to record more voices.
EVPs are also called Raudive Voices after Konstantine Raudive who
recorded 100,000 voices in the 1960’s and 70’s. He published "The
Inaudible Made Audible. The Association for Voice Taping
Research was founded in the 1970's in Germany, and American Association
- Electronic Voice Phenomenon in 1982.
Methods of recording EVPs
1. Recording all the time during the case or leaving your recording in certain areas unattended.
2. Recording at specific times and asking general questions to the spirits that may be present. (recommended)
Categories of EVPs
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.
How do EVPs get on the recorder or tape?
This is still being researched worldwide but our experiments support
one theory that Raudive and Bander formed while doing their
experiments. The spirit is using either existing sound
waves or EM energy to directly imprint the EVPs on the recorder or
tape. Other researchers believe the researcher can actually be
used by the spirit to imprint the EVPs using Telekinesis.
Analyzing EVPs
Most people use Cool Edit Pro or other high end software, but
there are other applications like Audacity that do a good job too. The
important features you will use areamplify, FFT filters and noise
reduction. Using these capabilities, it is common for an investigator
to find a Class C (or less) EVP and “clean it up” so that it is a Class
A EVP. You can also use programs like Cool Edit Pro to see if it
is out of the range of a human voice.
How do I record audio files into my computer?
If you dont have a USB capable recorder you can still get
your audio clips easily onto your computer. Ghost Hunters
were usin gthis technique before there were digital recorders to hook
up their tape recorders to a computer. You will need a
recording device with a headphone jack. The headphone jack will
connect to a computer Line In jack or Microphone jack with an ordinary
audio patch cord. You then would use your audio software or
Windows sound recorder which is built into windows to record the audio
onto your computer.
