Impression Differences by Placement of Front and Rear Microphones for Multi-channel Stereophonic Recording

Optimum microphone array for multi-channel stereophonic recording was presented by comparing impression differences. From the experiments the array using omni-directional microphones for left and right channels and a bi-directional microphone for center channel was evaluated better localization and spaciousness than the array using uni-directional microphones for left, right and center channels specially at off center position. And optimum position for surround microphones is drawn by calculation from room size considering the time difference between direct sound of front channel and early reflections of surround channel.
