Design of a Circular Microphone Array for Panoramic Audio Recording and Reproduction: Microphone Directivity
Design of a circularly symmetric multichannel recording and reproduction system is discussed in this paper. The system consists of an array of directional microphones evenly distributed on a circle and a matching array of loudspeakers. The relation between the microphone directivity and the radius of the circular array is established within the context of time-intensity stereophony. The microphone directivity design is identified as a constrained linear least squares optimisation problem. Results of a subjective evaluation are presented which indicate the usefulness of the proposed microphone array design technique.
