Electronic Voice Phenomena



Electronic Voice Phenomena

First published in Heart Soul and Spirit Magazine, Issue 4 Nov/Dec 2014, pags 22, 23


 In 1959, the world of paranormal investigation changed dramatically with the discovery of what is now called EVP, or Electronic Voice Phenomena.
 Ukraine born artist, Freidrich Jurgenson was as his summer house and decided he wanted to record some birds singing close by. It wasn’t until late that evening, whilst listening back to the recording, he made a discovery of a man’s voice in the recording. Knowing he had been alone in his garden, he could not account for whom the man was.
This discovery would lead Jurgenson on to record thousands of samples, of what he termed “Voices of the dead”, he was of course criticised for his work, but it did not faze him as he had one single recording that cemented his belief that these were indeed the dead talking to him. His dead Mothers voice.

He spoke of the recording in his book “The Voices from Space” published in 1964

 Jurgenson: "I was outside with a tape recorder, recording bird songs. When I listened through the tape, a voice was heard to say "Friedel, can you hear me. It's mammy ...." It was my dead mothers voice. 'Friedel' was her special nickname for me." 

 Although Jurgenson can be noted as a pioneer in the recording of EVP, it was Konstantin Raudive's experiments and laboratory testing that made the Spirit recordings famous, and also set many of the standards in the field for how we record EVP sessions in this day and age.

Raudive read Jurgenson’s book in 1964 and was inspired to test theories and procedures written within.
Raudive took the information he learnt from Jurgenson into laboratory trials and scientific testing. He tried many different recording devices, and soon, customised his own germanium circuit, known today as a “Raudive Diode”.
 Raudive took his testing seriously, and even placed the devices into a “Faraday Cage” (A metal cage that blocks radio and Television frequencies). Like most sessions, no voices were heard during the recording, but on playback, to the amazement of all involved, voices could be heard clearly, including Raudive’s own deceased sister, who said her name “Tekle” and Raudive’s nickname, “Kosti”.


In 1968 Raudive published a book titled “Unhörbares wird hörbar:- or “What Is Inaudible becomes Audible”, which has also been published in English as “Breakthrough”, He went on to write two more books before his death in 1974.

In the last ten years of his life Raudive collected around 100,00 audiotapes of “spirit” voices, it is claimed over 400 people became involved with his research and each and every one of them heard the voices recorded.

 In the modern Ghost Hunting age EVP is an essential part of any investigation process, we ask questions, we go home and listen for answers – I should state here the “Spirit” Box or “Franks” Box are not genuine Electronic Voice Phenomena, but “Radio Voice Phenomena” (a term I coined on my blog) – they are sweeps of radio frequencies and ARE audio pareidolia, not something that can ever be claimed as "evidence" of the paranormal.
 Anyone can have a go at an EVP session, there is nothing stopping you, you do not need expensive equipment or specialised training, but there are a few tips I would like to share with you, to get you on to your path of EVP discovery!
 Firstly, I recommend a voice recorder that has a usb or memory card built in, so you don’t have to sit at your computer listening back to the whole recording, saving it into a program. Rather than that wasted time, you can easily switch the file from the device to your laptop or pc.

 Try and get a voice recorder with a good microphone, brands like Sony, Zoom and Tascam currently have some reasonably priced, stereo microphone records that work exceptionally well. Even your phone or tablet now days have good enough microphones for experimenting with, or you can always buy an external microphone and plug it in.

 If you do EVP sessions, take note of your surroundings, who else is there? What natural sounds are happening?

 I try to always put my recorder down, or use a tripod to support it, so the sounds of my movements cannot be interpreted as an EVP (this does happen). In my team, we also have a video camera pointing at us whilst we record EVPs, that we can play back later on and see if any sounds coincide to our movements.

My wife Karen also takes notes as we work, in those notes Karen will write the time, where we are, what I ask and if any natural or man made sounds are happening at the time (cars driving past, birds flying over etc) – this gives us a little bit more information that we may have forgotten when we begin our review of the recording.

My next tip is a simple one, DO NOT WHISPER – if you decide to go out with a group of people, ask everyone who is with you to be silent whilst you record, but, if they have to speak, do so in a normal voice. This is for the simple reason that you may not know someone else has whispered, and when you get to review your EVP session you hear this amazing EVP...only to find out later that it was simply a team mate whispering...

Lastly, do NOT tell people what you believe an EVP says. Let the person listen and give their ideas first.
Why you ask? Influence... if someone tells you what an EVP says before you hear it for yourself, you are pre-influenced to hear what they say it is, rather than make your own determination as to if the recording is a genuine EVP or just some random mistaken noise.

As always folks, Be respectful. Be prepared. Be protected. Be safe.

What is the best Equipment for recording EVP?




What is the best Equipment for recording EVP? 


If you are interested in the paranormal and have seen the ghost hunting TV shows, you would know straight away what an EVP is, but if you haven’t had an interest, it stands for Electronic Voice Phenomenon.

 It is believed by most ghost hunters that EVP are the voices of the dead. Sceptics believe it is actually noises that we give meaning too (Apophenia[i]), they often point to the fact that the same people will not hear the same thing, unless one person states what they are hearing, then 90% of the time, both will hear the same thing after that time.
The sceptics do not consider the tireless work of Parapsychologist KonstantÄ«ns Raudive, who in the 1970’s spent many hours in his laboratory experimenting with EVP in closed, scientific conditions, logging various voices through his experiments.

The debate about EVP, like many things in the paranormal continues to this day, but I digress!
With all things in paranormal evidence gathering one needs to keep “evidence” in its purest form. In photography and videography this is referred to as a RAW Image File – which is basically a file that the camera has yet to process into a “standard saving format" such as TIFF or JPEG. Raw files are basically the exact image the camera sensor sees, before the computer inside process’s it and turns it into a JPEG or other files format

Audio formats s also have a variation of Raw files (lossless audio) known as WAV which stands for WAVE AUDIO FILE FORMAT - WAV is the Microsoft version of this format, Apple Macs use AIFF format (FLAC, and ALAC (Apple Lossless Audio Codec, used by iTunes) are other types of Lossless audio)

Wav. is the recording in its rawest digital form and is usually uncompressed audio recordings. This format is easily compressed into other formats such as MP3, but as with all compression, will lose some audio quality with the filtering that compression causes.

One disadvantage of the WAV file is its large size, which is due to the rawness of the audio. Many recorders limit this to a 4-gigabyte chunk, which is equivalent to about 6.8 hours of CD-quality audio.
Sony Sound Forge uses a 64bit recording option allowing for greater audio sample quality.
Mp3 was devised by the Moving Picture Experts Group or “MPEG” as most people know them. MP3 uses the “Lossy compression algorithm” to encode and compress data, this causes a significant loss of data to make file sizes smaller and easier to transfer. 
Advantages of MP3 are the ability to split and “album-wrap” audio files and the ability to upscale or downsize a file format and audio quality – however, neither of these are useful to the paranormal investigator.

Essentially what we are looking for is to keep our EVP files as raw as possible for ourselves and other investigators, as well as audio specialists to be able to evaluate what we have captured in its purest digital form. The MP3 format does not allow us to do this, thus the WAV files format is a much more useful tool – the only downside being when one tries to make a video of their EVP capture, some video editing programs use MP3 encoding as standard and therefore the audio quality will drop in the video.

 This can also apply to uploads to some social network sites and site similar to Youtube. 

Voice Recorders utilising WAV recording include (but not limited to😊
Zoom H1 Handy Recorder (the same model I used on Haunting: Australia)
Tascam DR-05 mk2 Linear PCM Field Recorder
Olympus LS-14 Linear PCM Digital Voice Recorder
Roland R-05 Studio WAVE/MP3 Recorder
Sony PCM-M10

Don’t be disheartened if you cannot afford a top of the range voice recorder, at the end of the day most modern phones will do the job just as well. They may not record in WAV. But that shouldn’t stop you at least trying to record an EVP session – heck, back in the early days of EVP, people were using real-real tape recorders, I even have a cassette recorder in my equipment bag and have recorded decent EVP session on it.

 Saying that though, if you are trying to hold your EVP session up to scientific scrutiny, then its best to use a high end, stereo recorder with WAV. Capabilities. It is also crucial you have at least one video camera locked off on a tripod filming you and your surrounding while you record – film using a visible timestamp that is synchronised with your watch. When you start your EVP session read the time out loud.

 Why is this crucial? The video will show any movements you make, it will also record background noise, or any noises you make subconsciously. In your EVP review, note how many minutes/ seconds from stating the time you hear anything you think might be an EVP, then go to your video and double-check that it is not you moving about, or something else you haven’t accounted for!

There are many audio programs for editing your audio such as:
Audacity
Sony Soundforge
Wavepad
Acoustica Digital Audio Editor
And a ton of others!

Good luck on your next EVP session, and say hi to the spirits for me!
