EVP or Electronic Voice Phenomena is a fascinating and somewhat controversial field involving the capture of what are apparently spirit voices onto magnetic tape or in a digital recorder. Some hunters focus almost exclusively on this technology, while others for one reason or another rarely or never pay much attention. Nearly everyone has tried it at one time or another with varied results. Is EVP an appropriate research tool, and if so, what are the pitfalls?
2. Setup is not difficult and can be done in many environments as it is small and unobtrusive.
3. Results can be startling and eerie - investigators may even get direct answers to questions.
4. Easy to replay for others on a computer or over the Internet. Can have a lot of "Wow" power.
2. EVP voices can be very indistinct or garbled and subject to misinterpretation.
3. Finding and purchasing a high grade setup can take a lot of research and cost a substantial amount.
4. Going through the data to find something that is anomalous may be time consuming and adds to the workload of an investigation.
5. Pulling the data to a computer for analysis from microcassette through an audio cable can be a challenge. (digital transfer recommended)
6. While generally easier to pull data from, most digital recorders use "lossy" compression schemes which will degrade audio quality.
7. Most software for audio analysis can have a steep learning curve - you may want to hire on a specialist.
8. Even if the voice is that of a spirit, how do you know that it is the one that you are currently investigating?
9. You can inadvertently record or pick up on private conversations that you did not intend to listen to.
10. I have seen people (even investigators) get seriously creeped out by the phenomena and refuse to work with it.
Despite the longer second list, I am not against EVP, but have remained very mindful of the cons listed above and found it easier to focus on other detection technologies rather than take the time to overcome the technical issues.
I took much of the following information from a now defunct webpage at what was http://www.nursehealer.com/EVP.htm though I have cleaned up some of the formatting and removed personal comments not my own. Credit goes to Mary C. Miller. I will gradually start reorganizing the page better and rewording/adding my own info.
When you begin to record, state the location, time of investigation, weather conditions, and investigators names (those present). You will be glad later when you are trying to figure out which recording went with which investigation/room/date.
Rating system for EVP:
The sounds that are discovered on audio tapes are in the ELF (Extremely Low Frequency) range, below the usual range for normal voice. These ghostly voices are thought to be the recordings of spirit voices. Some researchers offer up their EVP as definitive proof of spirit communication. There are other possible explanations for the sounds heard on tape that should be considered by the serious researcher or investigator.
