Schneider Disc

A stereo microphone device used primarily for capturing binaural stereo and a variation on the OSS technique. Similar to the Jecklin disc, the Schneider disc comprises a circular baffle of 30cm diameter with acoustic absorption material on both surfaces supplemented with a 12cm foam-covered sphere at the centre of the disc to better approximate the acoustic characteristics of the human head. Omni-directional microphones are placed on either side with a roughly 16.5cm spacing and angled outwards at 20 degrees.
