Ghost EVP
I haven't tried in awhile, but spent quite a bit of time in the past trying to capture evps via the evpmaker and audio and video cams. I used to go to grave yards with my audio recorder and video cam. I wasn't successful. But, I didn't get into all the sound/noise filters software etc. If a ghost wants to speak with me, I wanted it to be loud and clear. I don't care to listen to a quiet ghost. After experiencing much of what I have with the paranormal, most evps bore me. So, I wanted a ghost that knew how to come through in a reliable fashion. Similar to the ones the ITC people claimed to have been in contact with. I linked to some info. on their findings in another thread. The thread dealing with Spiricom I think.
