As I mentioned before, the primary issue I have with these audio files is the fact that they're clipped. When audio is clipped like that, it makes it almost impossible to determine the nature of the audio because a significant portion of the audio is missing.

From your description I'm gathering that this was an Analog recorder which was then later fed into a computer and digitized? If that's the case, I think that's where the clipping is coming into play. The output volume from the recorder (meant for a external speaker) is much higher than the input volume (meant for a microphone) from the computer. If my guess is correct, then I would suggest re-digitizing it but using the AUX/LINE IN jack on your computer.

Let me give you a graphic example of what I'm talking about. Below find a sample of the audio file you uploaded:



And this is a sample of a standard audio file which does not have clipping.



So, do you notice how the top one is somewhat square? That's a sign that the top portion of the audio was chopped when it reached the maximum volume of the device.

The reason why it makes it impossible to make any determination is because when the audio is clipped like that a simple low to mid-range sound can take on that demonic type of sound. In technical terms its because the higher frequencies are exentuated and the wave becomes square. This is the same type of effect used in guitar distortion boxes, and also to attain some of the special effects you hear in the movies.

So, I would very much like to hear a re-digitized version of the original if this is an analog recording.

sorry I could not make out anything it was going to fast..will try ans see if I can catch anything again..
