Binaural recordings

There is an artist named Allan Tarantino on randomnumber.nu/?p=494 that is using binaural microphones for his recordings. You can get an idea of the effect of using that type of mic by listening to his work. Its almost like being there.

Kip miswired the microphones to the stereo jack.

A complete amateur's mistake

By joining both positives and both negatives together he made a dual input MONO microphone.

Shortcut

If you want to take a shortcut on this project, and don't mind shelling out just a little more money, you can pick up two Olympus TP-7 "telephone recording microphones." These fit directly into your ear, and look a lot like high-end earbuds. Any sound going into your ear also goes through the microphone element, which is why they're so useful for recording telephone conversations, but they could also be wired into a stereo jack quite easily for binaural recording.
