Abstract:
Disclosed herein are microphone arrays for directional reception, along with related system, devices, and techniques. For example, a four-microphone array for directional signal reception may include first, second, and third microphones arranged such that projections of the first, second, and third microphones in a plane provide corners of a triangle in the plane. In some embodiments, a fourth microphone may be arranged such that a projection of the fourth microphone in the plane is disposed in an interior of the triangle. In other embodiments, the fourth microphone may be arranged such that the projection of the fourth microphone in the plane is disposed outside the interior of the triangle, and a distance between the first microphone and the second microphone is different from a distance between the first microphone and the third microphone.
