XY stereo recording
Using two CHM 21 hanging microphones in an XY configuration (coincident pair) is a good way to make stereo recordings, particularly of choirs. However, sound source locations are defined only by intensity differences. Adjusting the angle between the microphones determines the width and depth of the stereo image.
ORTF stereo recording
Developed by the French Broadcasting Authority, this technique differs from the XY technique by recording not only intensity differences, but also delay differences. The capsules are aligned at an angle of precisely 110° and 170 mm / 6.7 in. apart.
