EVP (Electronic Voice Phenomenon)- are voices or sounds found on electronic recordings that were not present or heard during the recording process. EVP is generally captured with a digital voice recorder or analog tape recorder.
ITC (Instrumental Transcommunication)- is the two way communication with spirits that can occur when using devices such as the P-SB7 Spirit Box or special modified radios like one of the many "Shack Hacks" that are available.
If possible, please use headphones when listening to these recordings. If you don't have decent speakers, you may not be able to hear a few of them very well or even hear them at all. The reason that some of the clips get louder during the answer part of the recording is because I've purposely enhanced the volume to help make out what is being said.
