The DIN Stereo principle is based on two first-order cardioid microphones spaced 20 cm (7.9 in) and angled 90° creating the stereo image.
Keywords: DIN stereo, cardioid, spacing
DIN stereo produces a blend of intense stereo signals and time delay stereo signals, due to the off-axis attenuation of the cardioid microphones together with the 20 cm (7.9 in) spacing.
If used at larger distances to the sound source, the DIN stereo technique will lose the low frequencies due to the use of pressure gradient microphones and the influence of the proximity on these type of microphones.
The DIN stereo technique is more useful at shorter distances, for example on piano, small ensembles or when used for creating stereo sound on an instrument section in a classical orchestra.
Since the recording angle of the DIN configuration is very close to that of the ORTF configuration, the resulting sound characteristics are comparable to the sound demo of the ORTF stereo recordings.
