Several years ago, my son Steven had a very close friend who committed suicide and it was a very tough time for many of the kids who had known him in High School. Steven took it real hard and it was a big blow to him. During those days, all Steven could talk about was how much he would miss his friend.
Around that same time, my other son Mark had started using a voice activation program on an old computer he had in his room, and one day Mark decided to hook the telephone into it and tape a call he was on with a girl he knew. At one point during the call, he asked the young lady something, and as she answered, it came through garbled. Mark didn’t think much of it at the time, but later he started to play with the program as he replayed the conversation.
Later that day, Mark came running downstairs quite startled. He was very insistent upon having me come up to his room and hear the recording.
When I got upstairs, Mark began to explain that he was a little puzzled by the part of the recording that came out garbled. I noticed he had it cued up, and then as he played it for me, it was indeed garbled. You could not understand what the young lady had said. Then he clicked on a section of wavelengths and said, “Now I am going to isolate the sound wavelengths so we can hear just the girl.”
He did that, and I was able to hear, crystal clear what she had said. I told him that was pretty cool, but he looked at me seriously and said, “Wait until you hear the other part.”
He clicked on the wavelengths again, but isolated and removed the wave that contained the girl ‘s voice, and I was astonished when he played the sound of what was left when her voice was removed. It was a simple, male voice.
“Steven!” it said.
