Microphone array for panoramic audio

The utility model relates to the technical field of audio recording and audio signal processing. A microphone array for panoramic audio is characterized in that geometric centers of four identical heart-shaped pointing microphones are located on the same plane S and form a square ABCD, and the installation directions of the four identical heart-shaped pointing microphones are respectively 45 degrees, 45 degrees, (-45 degrees,-45 degrees), (135 degrees,-45 degrees) and (-135 degrees, 45 degrees). The negative sign indicates that the distance from the azimuth stop edge to the azimuth start edge is clockwise, the pitch angle of each heart-shaped pointing microphone takes the edge where the plane S is located as the pitch angle start edge, and the negative sign indicates that the distance from the pitch angle stop edge to the pitch angle start edge is clockwise. An output signal generated by the microphone array provided by the utility model still accords with a first-order high-fidelity stereo sound replication
