What is EVP?

EVP Recording Techniques


  What is EVP and what does EVP stand for? EVP is Electronic Voice Phenomenon. It is the appearance of intelligible voices on a recording medium such as a tape/digital recorder that has no known physical explanation. Many voices are thought to originate from deceased people.

  This is one of the primary reasons that people first began experimenting with EVP. Others study EVP to better understand how and why it works, and to improve EVP experimental techniques and how we can get better recordings.

  The recording equipment doesn't need to be expensive or elaborate to work with EVP. As in any field of interest, some people are better at recording EVP than others. With patience, perseverance and good listening techniques, you should be able to record and hear EVP messages.

Characteristics of the Voices

  The recorded voices may be very quiet and are often difficult to hear and understand at first. Most EVP investigators say that they have developed an “ear” for the sounds, after learning to distinguish them from background noise. And, for EVP analysts, this is a true statement. The voices can often be recognized as male or female, young or old. Messages usually last two seconds or less and are most often two to four words. The words may be spoken very quickly, and there is often a distinctive cadence to EVP voices. But, Spirits can also say sentences and and ramble on if they choose to do so.

Basic Equipment Needed

    Audio Recorder:

  EVP has been recorded on all types of equipment. The built-in microphone on a portable tape recorder tends to pick up motor noise. Therefore, it is best to use an external microphone. It is also best to use a cassette tape deck with mechanical controls that allow easy, repeated review of the voices. Be sure the recorder has a counter. People report recordings of EVP on telephone answering machines and many other devices that do not have external microphones. Digital Voice Recorders (also known as an IC recorder or digital note recorder) are fast becoming the recorder of choice, but they are best used with a computer to analyze and store the recordings.



  A microphone will help you make a record of your comments during the recording session, and introduce external sound sources. EVP messages will have more meaning if you have a record of the questions asked and the recording circumstances.



  Since the EVP voices frequently are not loud, many voices will be missed unless headphones are used. The earmuff type, which completely covers the ear, is usually used. Ear buds aren't very good at all. You truly want to use noise canceling headphones/headsets that make it easier to hear the EVP clips.



  Any low noise, high sensitivity tape may be used. 60-minute tape (30 minutes each side) is recommended. It is best to record in 1 to 2 minute sessions at one time. This doesn't sound like much time recording at one session, but when you go to analyze the sessions, it's like doing 20 minute sessions.

Recording Procedures


  Entities will speak on tape at any time of day or night. In the beginning, however, it is advisable to record at a regular time and place. By doing this, the entities learn when you will be recording. After making a connection with the entities, you will be able to collect EVP at any time and in any location. Try to find a place that will be quiet, free of interruptions and a lot of background noise. Background sounds are okay, but it is important that you are aware of this so that you will recognize what sounds are natural and what sounds are EVP. Always try to limit your background noise whenyou can. Keep your recordings short. You will want to listen to each part of the recording very carefully and this can take time.



  Vocalize your comments during an EVP session. Many investigators begin with a short prayer and an invitation to friends on the other side to participate in the experiment. It can be helpful to begin an experiment by speaking your name and the date. We have found that the entities will often come through as soon as the recorder is turned on. These beginning messages are often the loudest, so it is a good idea to turn on the recorder and wait a few seconds before announcing yourself and then ask questions. Your questions should be recorded, and you should leave a period of time between each comment for the entities to respond.

  It's best to try to leave at least a 15-20 second space in-between questions to give the Spirits time to answer. Most investigators get impatient and don't give enough time in-between questions.

  Some investigators make an 'appointment' with the intended Spirit the day before during prayer or meditation. Some also provide feedback before the session so that the Spirits will know how the last experiment went. It is not necessary to record in the dark. You will find that investigators try different types of devices and energy sources to help the Spirits communicate. You may also want to put written questions in the EVP experiment area the day before. We are told the entities can read these and may respond accordingly. Also, they can hear your inner thoughts. You might want to say what you want mentally several times, but it's always best to say your questions out loud.



  The paranormal voice is usually not heard until playback of the tape or digital recorder. Investigators report that the voices tend to become stronger and clearer as the Spirits gain in experience, but at first the voices may speak in whispers. Voices may not be recorded in every session and it may take several sessions for you to discover the first voice. Hearing the voices is a learned ability. The entities seem to learn through practice how to come through more frequently and more loudly.


    Classes of Voices:

  •  'Class A' voices can be heard and understood over a speaker and through noise cancellation headsets by most people.

  • 'Class B' voices can be heard over a speaker, but not everyone will agree as to what is said.

  • 'Class C' voices can only be heard with headphones and is difficult to understand. Class B or C voices may have one or two clearly understood words. Loud voices are not considered 'Class A' EVP clips.


    Keeping a Journal:

  Maintaining records in a journal of recording results is very helpful and useful. Include the date, time, weather information, place on the counter where the message is received, the message itself, and the question asked. Be sure to label the tapes if you do not use a digital recorder. Investigators report feel weather may affect results.

Computer Recording


  You can use a computer for recording also if you have a laptop or another type of computer that can be on the go. Your computer should have an audio input jack, speakers, headphone jack and sound player application of some form. Windows comes with a Sound Recorder application that will work. A sound editor like 'Adobe Audition' or 'Source Forge Audacity' are the most popular because these applications allow for easy amplification, filtering and reversing of the sound files. Source Forge Audacity is a free program that you find on the internet. You can learn more about Adobe Audition here: Aobe Audition

  You can either make the recording on a tape recorder and then play the tape into the computer for review, editing and storage, or attach a microphone directly to the computer and use the sound editor as a tape recorder.

  When transferring into a computer, make sure the computer is set for “Line In” recording in “Sound and Multimedia” in the “Control Panel” of your Personal Computer. If you must take sound from the “Earphone” jack of your recorder, consider purchasing an “attenuating cord” to match the difference in resistance between the two jacks. Radio Shack can help.


    About Digital Voice Recorders:

  If you are using a digital voice recorder, we recommend that you listen to the playback on your computer. You will be surprised at the quality of the sound track when it is not listened to with the little built-in speaker. You don't need to use an external microphone, as the recorders do not make internal noise.

  Should you decide to purchase a digital voice recorder for EVP, keep in mind that cheap is good. The less expensive recorders usually use a lower sample rate, which produces more noise and it is that noise we believe the entities use to form the voices, which is also known as "white noise."

  Do You Have Questions?

  These instructions are for the most common technique for recording EVP. We have found that EVP may occur in any technology that will record voice. With this in mind, it should be clear that there aren't any rules in EVP.  If you need any help, please feel free to contact us at: info@thespiritresearchsociety.com
