Ok guys how do you correct the comb filtering between your two ears? Stereo headphones? No your brain has done that for you already as you reached child hood. Its like learning perfect pitch. Isn't it amazing all the things are sensory systems and our brain do for us without us being aware. Recording is a very simple process as long as each mic remains discrete. Its when the sound comes out of the speakers that weird things begin to happen. Its why there's a real fascination with full range single driver speaker systems. Remember as much as we try making the process of bring ing Hi-fidelity into the home an exercise in science, for now it is an ART.
