The tapes have slightly degraded in quality over 15 years, but the voice captured at the time was impactful enough that it convinced Ben and the group that there IS something to the EVP phenomenon. Technology has somehow caught up with detecting intelligence in another realm or dimension. All possible and rational explanations were eliminated and yet there was a giggle on the tape and then a whisper against the microphone. Right after Ben remarks to the group that he wishes he could have taken them there at another time when he could have shown them something that might have scared them, a voice seems to press against the recorder in a long, drawn out breath that says, "Get.... brother". It could also be "mother". Remembering that the nearest people next to Ben were his two sisters who were a good 10 feet away, the voice sounds remarkably close. Standing next to a creek, the recording was chilling to play over and over and imagine what message the child or female was trying to say. Eventually, Ben played the tape for his parents whom he thought would disapprove of his exploits (this was at a time when ghost hunting was often seen as synonymous with seances). Instead, his parents became quite excited with the EVP and asked him to play it several times. Ben was hooked and the rest is history.
Now digitized, take a listen to the whole section of unedited audio. It starts with a discussion of the creepy man who was wandering through the park. At :24 seconds, you'll hear a very clear and odd giggle. Then once Ben finishes saying, "... more fun" at :43 seconds, listen carefully. It's very subtle at first and quite underwhelming for a first EVP, until you play it several times. A breathy inhale and single syllable "Get" is followed by a drawn out two-syllable "brother" or "mother" at :46-:47. Almost like a child out of breath, the voice is interrupted soon by sniffling and the group moving on to a new location.
