摘要
Already in the 1970s, the idea of using continuous harmonic functions of scalable resolution was described by Cooper and then Gerzon, who introduced the name Ambisonics. This chapter starts by reviewing properties of first-order horizontal Ambisonics, using an interpretation in terms of panning functions. And the required mathematical formulations for 3D higher-order Ambisonics are developed here, with the idea to improve the directional resolution. Based on this formalism, ideal loudspeaker layouts can be defined for constant loudness, localization, and width, according to the previous models. The chapter discusses how Ambisonics can be decoded to less ideal, typical loudspeaker setups for studios, concerts, sound-reinforcement systems, and to headphones. The behavior is analyzed by a rich variety of listening experiments and for various decoding applications. The chapter concludes with example applications using free software tools.
