Recording Raudive Voices
methods have been used to record Raudive voices.
Traditionally a tape recorder (reel-to-reel or
cassette) is used although it is now possible to
use digitial recording (see below). The following
procedures are commonly used:
- Recording using a microphone
in a quiet room, or with the microphone
sealed in a soundproofed box.
- Recording with no microphone
- Recording "white
noise" (hiss) from a radio that is
tuned between stations.
- Recording using a crystal
set (diode receiver) plugged into the
typically last only for a few minutes. This is
because intense concentration is required in
order to hear the voices on the tape, which
usually has to be replayed several times in order
to decipher the speech. Use of headphones is

you have a sound card and a decent browser, you
can hear Raudive Voices now by
clicking on the buttons below. These are short
snippets of a longer recording that I made using
the simple procedure described in the next
section. To hear the voices at their best you
should play them at maximum volume through
headphones. In both cases you should be able to
hear a definite "English" male voice.
You may need to replay the recordings several
times in order to make out the words, which are
quite indistinct. The first clip seems to be
saying something like "Do you like
potatoes?". The second clip sounds to me
rather like "five thirty and four-eye".
Different words may suggest themselves to you.
these recordings were made
a number of experiments using microphones and
radio hiss, none of which were particularly
successful, I decided to try electronically
generated white noise. This has the advantage of
ruling out the possibility that a microphone may
pick up a distant voice or that stray radio
signals may intrude into the between-station hiss
(critics have suggested both possibilities).
Rather to my surprise, I obtained immediate
results. Both the above samples were taken from
my first one-minute recording. In addition there
were several other similar voice fragments within
the same recording. Furthermore, I have found the
method to be replicable. So that you can try out
the method for yourself, here are the technical
details of the procedure that I followed.
a digital audio editor (Cool
Edit), I generated 60 secs of white
noise (sample rate 44100, mono, 16 bit). This
produced very faint suggestions of a voice, but
too indistinct to make out any words.
then decided to transform the recording using the
editor's noise reduction facility. After this, I
amplified the resulting waveform until it was
loud in the headphones. On listening carefully to
the recording, a voice or voices could clearly be
order to produce files small enough to be
downloaded on the Internet, short snippets were
selected and the sample rate was converted from
44100 to 8000. The files were then saved in
Windows PCM format (wav). This conversion has led
to a small decrease in sound quality, but the
voices are still easily recognisable.
voice phenomena have not been widely studied by
parapsychologists, who have generally been quite
sceptical of the whole procedure. In addition to
the criticisms mentioned above, it has been
argued that the voices are simply subjective
intepretations - that we tend to hear voices in
random patterms of sound rather in the way that
we often see faces in random visual patterns. The
suggestion is that because of the significance to
humans of speech and facial recognition, the
human brain has an in-built tendency to create
these perceptions even when there is no
"objective" basis for the experience.
For others, however, the Raudive Voices are
genuinely mysterious, even paranormal. Some even
believe they open up the possibility of
communication with the dead.
