The Spatial Equalizer

Abstract

Complete reproduction of spatial impression of sound is what human beings have dreamed to have. It is interesting, however, 3-D sound cannot be scientifically well defined. The sensation of 3-D sound can vary with listeners and reproduction environments. To tackle this problem, an interface that can implement the desired 3-D sound in space and time by the listener is proposed. The interface, called “Spatial Equalizer”, controls the sound field using a point or multiple points related with the location of the virtual sound source. The user controls the points and listens to the sound until it is satisfactory.
