Very annoying, but that's a good thing! Duplicate it, stretch it a bit, and change the pitch by a semitone, then play it back with the original and you've got a real ear-bleeding effect (which is what I was after).
So you made it, thank you!! It can be heard and sounds very 'batish' :-) But what did you do? the soundgram is really WEIRD, there are incredible harmonics all over the sample, have look at it: http://www.flickr.com/photos/dobroide/156659390/
