Ja um pouco antigo mas decidi partilhar na mesma para quem ainda não ouviu.

Holophonic recording, also known as holophony or holophonic sound, is an 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 Argentine researcher Hugo Zuccarelli which is a form of binaural recording.)
