The Stereophonic Zoom: A Practical Approach to Determining the Characteristics of a Spaced Pair of Directional Microphones
The intensity and time differences for a spaced pair of cardioid microphones can be calculated as a function of sound source position and, various spacing and angles between the microphones. This information, together with the physiological limits of the stereophonic listening situation, enables a usable angle for coherent stereophonic recording (recording angle) to be determined. For the same recording angle, different values of spacing and microphone angle enable the sound engineer to choose the subjective stereophonic quality desired.
