An interesting experiment is Binaural recording.
It was experimented with in the 70's but didn't really catch on.
What you do is mimic the human head with 2 mics where your ears would be (Following?!)
There was a German "Head" you could buy (Kuntskopf sp?) that actually had high quality mics implanted into a fake skull. (Yes you would look pretty stupid walking around with it!)
It only worked if replayed through headphones though. Somewhere I have a demo record done by Sennheiser I think. Will try and find it.
I did do a demo in London on a night shift once, and the results were pretty amazing.
You could probably get the same effect by taping a couple of electret mics to the arms of a pair of glasses!!
It really is rather weird. It's all today with the phase differences between the two mics, and the fact that there is a dense object between them! (No offence intended!!)
