Periphony (sound reproduction in both vertical and horizontal directions around a listener) may be recorded among others, via practical two-, four-, and nine-channel systems. Matrix parameters and microphone techniques are described for 19 different systems, and a design procedure for other periphonic systems is given. Amplitude and energy directional resolution are discussed, as is compatibility with current horizontal-only systems.
