EBS
A microphone setup developed by Eberhard Sengpiel of the Berlin University of the Arts. This setup is based on two cardioid microphones spaced 25 cm (9.8 inches) apart and at an angle of 90°. Similar techniques use other angle values, but 90° is considered easier to set up. The EBS technique can be categorized as a near-coincident design.
