Well, it's Usenet, what did you expect?

I think the whole ghost sound thing is bunkum also, but that's because I
have never seen any reasonable evidence. So, it would be in my best interest
to tell you what I consider reasonable evidence, which is what plenty of other
people will as well. (And that involves no lossy compression, etc.).

I don't think there is a good book out there on forensic audio work, really.
Maybe Eddy Brixen will write one someday.

There's a nice introduction with links to further reading he-

One thing that you will find is that it's a *lot* easier to get useful
results if you start with a stereo recording of the soundfield.

Also, bear in mind that in areas where hauntings have been reported,
there is often a strong VLF (1-10Hz) sound source, so you possibly need
a recorder that will go down that low.

Slightly OT, on the subject of pictures of supernatural events, I have
met a couple of people, claiming to have seen ghosts, but with unusable
pictures, who haven't even gone to the trouble of learning to combat
sensor noise in a digital camera. The pictures were a lot clearer after
they started using the right processing algorithms. No ghosts, though...
