METHOD OF AND APPARATUS FOR REALISING SPATIAL SOUND EFFECTS

摘要

A method and apparatus for realising spatial sound effects. The essence of the invention is the division of one or more recorded signals before amplifying prior to reproduction into more parts with summarized power substantially equal to that of the recorded signal and reproduction of the divided signal parts with at least four acoustic radiators. The apparatus includes a transformation unit (A) and a reproducing or recording unit (B) wherein the transformation unit (A) includes controlling means (5) and controlled dividing means (2) wherein the controlled dividing means (2) are equipped with a circuit connected to the output of the controlling means (5) for dividing the electric signal forwarded from the input (6) of the transformation unit (A) substantially without losses for at least four advantageously eight outputs (7).
