 Electronic Voice Phenomena The History ...
Voices from beyond can easily be recorded using a regular cassette tape recorder with an external microphone. The discovery was made in 1959 by Friederich Jurgenson, a Sweedish researcher, and it started a wave if interest in this field. Jurgenson was using a common tape recorder to record bird songs when he discovered mysterious voices in the recordings. Mixed with the backgorund sound, the wind shaking the leaves in the trees, it was possible to hear the conversations of people who were not visible in the place where the recordings weree made. After Jurgenson's discovery, many other researchers began to experiment, trying to pick up voices from beyond. The most important of these researchers was Dr. Konstantine Raudive. He died in 1974 but left a number of works aimed at convincing humans that contact between the dead and the living is possible. Dr. Raudive applied the principal of stochastic resonance to his research. The basic idea is that background noise acts as a carrier and can be modulated by any other signals present in free space. Without background noise, these signals, (voices of the dead), are too weak to be detectable, but in the presence of a noise (white noise) their levels increase beyond the threashold of detection and become clear...sometimes even loud. White noise can also be describes as a signal with no definite frequency. EVP SOFTWARE EVP RECORDERS AND SUPPLIES  
Recording
Audacity can record live audio through a microphone or mixer, or digitize recordings from cassette tapes, vinyl records, or minidiscs. With some sound cards, it can also capture streaming audio. * Record from microphone, line input, or other sources. * Dub over existing tracks to create multi-track recordings. * Record up to 16 channels at once (requires multi-channel hardware). * Level meters can monitor volume levels before, during, and after recording. Import and Export Import sound files, edit them, and combine them with other files or new recordings. Export your recordings in several common file formats. * Import and export WAV, AIFF, AU, and Ogg Vorbis files. * Import MPEG audio (including MP2 and MP3 files) with libmad. * Export MP3s with the optional LAME encoder library. * Create WAV or AIFF files suitable for burning to CD. * Import and export all file formats supported by libsndfile. * Open raw (headerless) audio files using the “Import Raw” command. Note: Audacity does not currently support WMA, AAC, or most other proprietary or restricted file formats. Editing * Easy editing with Cut, Copy, Paste, and Delete. * Use unlimited Undo (and Redo) to go back any number of steps. * Very fast editing of large files. * Edit and mix an unlimited number of tracks. * Use the Drawing tool to alter individual sample points. * Fade the volume up or down smoothly with the Envelope tool. Effects * Change the pitch without altering the tempo, or vice-versa. * Remove static, hiss, hum, or other constant background noises. * Alter frequencies with Equalization, FFT Filter, and Bass Boost effects. Adjust volumes with Compressor, Amplify, and Normalize effects. Other built-in effects include: * Echo * Phaser * Wahwah * Reverse 
Sound Quality
* Record and edit 16-bit, 24-bit, and 32-bit (floating point) samples. * Record at up to 96 KHz. * Sample rates and formats are converted using high-quality resampling and dithering. * Mix tracks with different sample rates or formats, and Audacity will convert them automatically in realtime. Plug-Ins * Add new effects with LADSPA plugins. * Audacity includes some sample plugins by Steve Harris. * Load VST plugins for Windows and Mac, with the optional VST Enabler. * Write new effects with the built-in Nyquist programming language. Analysis * Spectrogram mode for visualizing frequencies. * “Plot Spectrum” command for detailed frequency analysis Audacity is open source software and distributed under the GNU General Public License. We offer this program on CD along with a brief written and video tutorial plus assistance via email with editing your EVPs:
Our Price is $9.50 personal checks and money orders accepted Pure White Noise for EVP and ITC Experiments 
This
audio compact disc contains 100% genuine white noise, the best quality
white noise you can get. So-called "white noise generators", which sell
for a lot more, are usually frequency-biased in their attempt to simulate
white noise. This CD was produced by incorporating data from natural chaotic
systems, thereby obtaining 70 minutes of frequency-neutral and non-repetitive
white noise. Don't take any chances with your subconscious! Get the "whitest"
white noise there is.
The white noise has been professionaly recorded at the maximum volume and frequency resolution any audio CD can hold, resulting in a sound that contains every frequency from 0 Hz to 22,050 Hz (22.05 kHz) at equal power, with absolutely no distortion or repetitiveness, in stereo. This is as good as white noise gets! How To Use This CD: Simply insert it into any CD player, start at the lowest volume setting, hit the "Play" button, and slowly adjust the volume upward until it is just loud enough to mask out all background noise. If you set your CD player to "repeat", you will get an endless supply of white noise, otherwise the CD will play for 70 minutes. This
is better than those white noise generators you see on sale for $60.00
to $100.00. Those all need to be plugged in. With the CD, you can use
any portable CD player, so you can have white noise anywhere...even outdoors.

If you have MS Windows you do not need any other software to download the audio, you can use Windows Sound Recorder. This is how researchers have been transfering EVPs to their computers for years.
personal checks and money orders accepted Sony EMC-F8 Omnidirectional Microphone
~Unique power on/off switch ~Operates with CR2025 battery ~ Aprox 2" wide and 3/4" high EVP
stands for Electronic voice Phenomenoa. Attempting this type of recording
is easy. External microphones are recommended by most paranormal investigators.
Use of these microphones will avoid tainting your recording with noises
from the internal parts of the tape recorder. Omnidirectional microphones
are ideal because they pick up sounds from all directions equally well.
These can be used with regular, and microcassette and digital recorders to help reduced noise and echo.
