A sound capture system may include a first number of first omnidirectional microphones that provide first output signals with an omnidirectional response pattern and that are disposed at different positions in a first equidistance from a point of symmetry. The sound capture system may further include a second number of second omnidirectional microphones that provide second output signals with an omnidirectional response pattern and that are disposed at different positions in a second equidistance from the point of symmetry, and an evaluation circuit that is configured to receive the first output signals and the second output signals, and to superimpose the first and second output signals of pairs of omnidirectional microphones for producing, in response thereto, third output signals with an directional response pattern. The second number is a multiple of two and the first equidistance is smaller than the second equidistance. Each of the second omnidirectional microphones forms with another of the second omnidirectional microphones a pair of second microphones, the microphones of a pair of second microphones being disposed in line with each other and the point of symmetry. |
