EVP: The occurrence of Phantom voices on tape. Also called Electronic Voice Phenomenon

How to record EVP - You can use any analog tape recorder, but do not use the inboard microphone. Plug an external microphone into the microphone jack and extend the mic no less than 3 feet from the recorder to be sure the noise is not from the sounds of the recorder.  Anyone who enters the area should clearly state their name. Note any unusual loud external noises you hear that might show up in the recording. You can later plug the recorder into your sound cards line in jack to record the sounds onto your computer.
