'''Holophonic recording''', also known as '''holophony''' or '''holophonic sound''', is an [[sound reproduction|audio]] recording technique which operates on a similar principle to [[holography]], except it applies these principles to sound and audio recording. It is related to the technique of [[wave field synthesis]] whereby sound is sampled over an area, usually a sphere, enabling the recreation of the shape of the sound wavefront as well as its direction. It is derived from the [[Huygens' Principle]], which conveys the idea that an acoustical field within a volume can be expressed as an integral. It has some similarities with higher order [[Ambisonics]]. The result has been reported to be realistic and life-like three dimensional sounding audio recordings which have been said to exceed the realism of stereo sound.
(This is not to be confused with [[Holophonics]] designed by [[Argentina|Argentine]] researcher Hugo Zuccarelli which is a form of [[binaural]] recording.)
