It sounds like pigs being tortured and it has been going on for a couple of weeks, sometimes starting as early as 10:00PM and continuing on and off until generally around 5:00AM. Although it sounds like pigs being tortured, it is probably the sound of human voices slowed WAY down. My guess is it's slowed down by more than a factor of two--but I'm not sure. If it were only a 2:1 slowdown, wouldn't I be able to decipher the words being spoken? I can't do that at all. I suppose it's possible that, when sped back up, there would be no real English words--just sounds that resemble words. If somebody cares enough and has a tape recorder that can play back recordings at a speed higher than that at which the recording was made, we might find out what the original material was. For now, though, it is some of the weirdest-sounding stuff I have heard on the radio since "Surfin' Bird" was popular. (Bird, bird, bird; the bird is the word.)
