Generalized encoding and decoding functions for a cylindrical ambisonic sound system

摘要

In this letter, we present generalized encoding and decoding functions for an ambisonic system. Our approach provides matrix representations for optimum encoding and decoding for both odd and even number of N loudspeakers. Particularly, we present ambisonic components (signals or channels) for even N and a parameterized decoding equation for the optimum localization.
