MS, ORTF and stereo microphone techniques, MS uses a co-incident pair
of microphones, but instead of having mics for left and right, you
have Mid(cardioid) and Side(fig) mics, when the two are added together
you get a left signal and when they are subtracted you get a right
signal this means that the stereo width can be controlled at mix down,
being co-incident all of the stereo information is percieved through
amplitude differences. ORTF utilises two identicle cardioid mics
seperated by about 17cm and angled 110°, the stereo perception is
created by time and amplitude differences.

These types of effects can be simulated quite easily in csound
obviously using 
level differences as well as delays, filters can also be used to make
one side of the image less bright, which simulates the effect that a
persons head has, the 'hrtfer' UGEN in csound actually does these
things in a much more sophisticated way, though where you get the
HRTFcompact file from I do not know.
