One important capability of this tool is the ability to review individual video frames as if they were individual photographs. Video capture into the computer, editing and selective saving are capabilities that make it possible for anyone, even with a very inexpensive video device, to conduct video ITC experiments. Sound editing software, such as commonly used Cool Edit , permits the use of a personal computer for EVP recording, sound editing, filtering, stretching or compressing of sound tracks, and easy reversing of sound tracks. For instance, the EVP experimenter no longer needs to modify a tape recorder to to play an audio tape in the reverse direction. Also, a background sound is commonly used during EVP sessions.
Experimenters know that they are recording nonphysical information.
Their aim now is to determine how to improve that communication, and thereby, to determine who they are communicating with. Most members have come to believe they are communicating with people who have transitioned out of physical life. Some believe that there is a good possibility that the voices they record are little more than information recorded into the fabric of the physical world. A few think the idea that the messages are nonphysical in origin is all nonsense, and are trying to prove this by determining their physical source. Since there is considerable evidence that experimenters are receiving communications from deceased people, this Association maintains a focus on the nature of possible nonphysical worlds.
