Electronic Voice Phenomena
Electronic voice phenomena (EVP) are "spirit voices" that are said to manifest themselves on audio recordings. This can be one of the best forms of evidence an investigator can obtain.
Tips for recording EVP
Both Analog (cassette or micro cassette) or Digital recorders are acceptable and quality models can be purchased rather inexpensively.
Use an external microphone to eliminate any chance of internal machine noise from contaminating the recording.
If using an analog recorder always use a new tape. Used tapes are suspect and should be considered contaminated.
Always use only one side of the tape. This will eradicate any possible sound bleed through or claims of contamination.
Always test your recorder before using.
Always bring extra tapes and batteries for the recorder.
Try to record where there is not a lot of extra noise like near a busy road, crowds, etc.
Use a loud clear voice to ask questions. Never whisper. Whispering may appear as false evidence.
Pause between questions to allow the spirits to answer.
Always make a comment on the tape when something happens that should be ignored like a slamming door, common noise, or someone talking far off. This ensures that when the recording is listened to sometime in the future, these common noises aren't mistakenly thought to paranormal.
Listen to your recordings in a quiet comfortable place where you will not be interrupted or distracted.
Use high quality headphones or speakers when reviewing the recordings.
Have a notebook and writing instrument so you can capture the location on the tape of any EVP that you captured.
