XParanormal Detector analyzes anomalous changes in the signal (the rapid single flux quantum, if you want to dive that deep) of your Wi-Fi or network adapters. It communicates its findings onscreen through sensors, ghost radar, and graphs.
       Once you see some spikes in the chart, get ready for the action. Using the data, the program can spit out a word that a nearby spirit is trying to communicate. A built-in EVP (electronic voice phenomenon) device can be used to record up to a minute of sound through your microphone. Let a chatty ghost get a word in edgewise! If you buy the premium version ($19.95) you can capture up to an hour of EVP, and you can fill out log books to document your paranormal investigation, including an activity history that records every anomaly.
      The company takes pains to market its product as entertainment. Regardless of whether you believe in what it does, it’s incredibly fun to have around. Run it in the background while using your PC to creep yourself out, or use it with friends to prove your place really is haunted. The free Basic edition doesn’t have much use past the novelty, but the Premium edition offers plenty for the avid ghost hunter.

      My thoughts: As a paranormal investigator I have been using this software for many years. It's more for fun than using it for definitive evidence of the paranormal. There were a lot of times over the years when certain words were spoken that matched up with something or some activity happening at that time that left us shaking our heads.
