A stereo recording technique where two cardioid microphones are spaced 20 cm and angled 90 degrees creating the stereo image. This is remarkably close to an ORTF configuration. The DIN stereo produces a blend of intensity between stereo signals and time delay stereo signals, due to the off-axis attenuation of the cardioid microphones together with the 20 cm spacing. If used at larger distances to the sound source the DIN stereo technique will lose the low frequencies due to the influence of the proximity effect on these types of microphones. The DIN stereo technique is more useful at shorter distances, for example on piano, small ensembles or used for creating stereo on an instrument section in a classical orchestra.
