OK guys and girls, this is what I've got...
I took the clip "as is" as I got it from Nick, and ran it through some Audio editing/enhancing software. The complete analysis took me about two
hours to get what I got here. I'll give the technical data/facts, and you can make from it what you want. I'll then give my personal opinion on the
results. As an agreement with Nick I will not give any indication as to what was said in the clip. Anyone who wants to follow the whole conversation
will have to talk to Nick about it.
The clip is exactly 1:00 (one minute) long with a size of 481,805 bytes with actual bit depth of 16 bits on both channels (left and right).
The clip contains the voice of a young female, which is the loudest of the voices. Comparing the sounds and listening to the dialogue, she is holding
the camera.
There is also a second voice, that of a young man (or boy if you may - Nick indicated that both the persons are 18 years of age.). This voice is much
softer, barely audible, and his part of the dialogue is limited to one to three word phrases. Comparing the sounds and listening to the dialogue, he
is probably laying on a bed/couch a distance from the camera.
Then there's a third voice. That's the voice Nick posted above. Because the voice is in a whisper I cannot make accurate assumptions as with the
other two voices. It does sound like a male person, older than the other two persons in the clip. It's a clear voice, i.e. I would guess anything
from 20 to at the most 45 years old. To allow the voice to be audible it had to be in close proximity of the camera, however not as close as the girl,
but much closer than the boy. I have listened to the whole clip about a million times (if not more) and was satisfied that the voice speak only once
in this clip. There is nothing spooky or "inhuman" about the voice. It says a single phrase "I want to have sex", beginning the phrase quite soft
but with greater intensity to the end of the phrase.
I was also satisfied that there were no other voices in the rest of the clip.
I can assure everyone that the phrase is in fact "I want to have sex". If I knew that this was going to be questioned I would have brought the
enhanced and filtered clip with me. I asked Nick not to indicate where the voice speaks the phrase, to ensure that I don't expect to hear something
at a certain point. I picked up the voice the first time round. No question about the claim that a voice speaks the alleged phrase in the clip.
There is no question that it is in fact 3 different voices.
The following analysis is called a
frequency analysis.
It contains a graph of the frequencies at the cursor position or at the centre of a selection. The x-axis (left to right) represents frequency
(measured in Hz), while the y-axis (bottom to top) corresponds to the amplitude of the corresponding frequency (measured in dB) on the x-axis.
This first graph shows the frequency analysis of "random" points where the three voices speak in the normal clip.
The green line indicates the "unknown voice".
The red line indicates the girl's voice.
The purple line indicates the boy's voice.
This is how a normal graph of any person's voice will look like, thus there is nothing funny or strange about it. No strange frequencies. The girl's
voice does not fall into the average female voice range, but that doesn't mean anything. Something as simple as smoking (being a regular smoker) can
change the range or it could just be her regular voice. This does NOT raise any questions or doubt at this point.
This second graph is also a frequency analysis but this time I enhanced the waveform to get samples with the same wave amplitudes. (I.e. to compare
the voices if they are played at exactly the same volume.) I also tried to get samples where the sounds (phrases) were more or less the same spoken by
each person.
Again:
The green line indicates the "unknown voice".
The red line indicates the girl's voice.
The purple line indicates the boy's voice.
Note that the green line (unknown voice) is a much straighter line than the girl's voice. This is what we would expect from a whispering voice -
because it speaks in a monotonous tone, while the girl uses a wide range of tones to voice herself. The boy's voice is also quite monotonous
(one-toned) as the graph indicates, and you would also hear this should you listen to the clip.
Again, this doesn't indicate anything strange or out of the ordinary. It does however confirm that we are definitely dealing with 3 different voices
here.
If there is still any question about this, below are the Histogram of the 3 voices, clearly showing that it's 3 different voices.
Boy Histogram
Girl Histogram
Unknown Voice Histogram
I also have statistics for all three voices, but it doesn't show anything of interest, thus I will only post it if anyone request it.
Phase Analysis
Now we're getting at the exciting part!!!
Using a Lissajous Plot graph, it lets you easily see any phase differences between the channels of the current waveform. (“Phase” is the amplitude
difference between channels.)
- A mono (in phase) waveform will display as a rising diagonal line from left to right.
- An inverse left channel 180-degrees out-of-phase waveform (the right channel is in phase) will display a line descending from left to right.
- A right channel-only waveform will display as a horizontal line.
- A left channel-only waveform will display as a vertical line.
- Most stereo audio is generally fuzzy looking, upward sloping from left to right.
- If audio has very wide stereo separation, the display will be going in almost all directions.
So throughout the clip the phase analysis looks like this: (I enhanced the clip to get bigger wave forms.)
It shows a mono (in phase) waveform as a rising diagonal line from left to right. This is not unexpected because we know that the digital camera
records in mono.
BUT take a look at this!!!
This is how the graph looks while the unknown voice speaks! A line that "is generally fuzzy looking, upward sloping from left to right"... This
means that the voice is speaking in stereo! Absolutely mind-blowing!
But what does this mean?
We know for a fact that the camera cannot record in stereo, it is absolutely impossible. Thus the voice had to be added somehow afterwards.
If the voice was added on purpose, i.e. if this is a hoax, then it was done exceptionally well. There is no, and I mean not the faintest indication
that the waveform was edited. There is a loud "click" that might have indicated that the clip was edited, but this is ruled out by the fact that the
click is during the phrase (I want to have sex) is spoken.
I also removed the voices just to hear the background noises (white noises), and although the noise is minutely "softer" during the said phrase than
right before or after it, the differences is almost not notable, and still exactly the same as on other parts of the clip.
So, there you have it. Hope it's not an information overload, make of it what you want. I do not claim to be
the expert on sound clips, but I
have been working with sound for at least 7 years now - more music than "random sound", but still, the same rules apply.
So here's my opinion:
I have no idea how the voice landed on the clip - in stereo. Thoughts that come to mind is "ghost in the machine"...
A question that's bothering me is how your friends picked up on it. Although it's clear enough, you still need a good ear to randomly pick it up,
and not just write it off as white noise. Or their sound was just really loud?
From what I've read here, as well as the correspondence I received from Nick, I believe that he is NOT trying to pull one over us. He honestly
believes the voice on the clip to be that of a ghost. Whether his friends are playing a joke on him, remains to be debated.
But Nick, looking at what we've got here, I believe you've got yourself some ghost activity. Seeing the video would have made the case water-tight,
but the situation behind the clip is extremely complicated, thus we'll leave the actual video footage out of it. But I still believe your story.
This is some of the best and most convincing EVP clips I've heard.
I suggest you start your ghost hunting. Try to get some more EVP clips. Be sure to contact Amuk - the resident ghost-hunter - for help. (I don't know
if he's active again, but he'll be able to help you.)
It's just strange that a "ghost" would say what he did. Looking at the circumstances, I'm not surprised, but still.... He's a ghost. Do that have
that kind of ...err... emotions? He also doesn't sound hostile, so I don't think you need to be scared of him. Just be careful as the "activity"
might elevate into something dangerous. Just remember that nothing can hurt you without your consent.
Sorry, I don't mean to scare you. Just excited about this.
Please keep us updated if you find some more interesting phenomena.
