Surround sound field reproduction system and surround sound field reproduction method

Abstract

A surround sound field reproduction system and method is disclosed by which, in such a case that a listener changes its posture so that a portion of a video image to which attention should be paid may be observed in front of the listener, a sound image can be localized accordingly in a direction in which the video image is observed in front of the listener. Specifically, the surround sound field reproduction apparatus includes a plurality of horizontal panners for receiving a plurality of sound signals from microphones disposed horizontally and cooperating with each other to control the horizontal localization, and a vertical panner for receiving sound signals from microphones disposed vertically to control the vertical localization. The horizontal panners level-distribute the received sound signals to a plurality of output channels provided corresponding to surround reproduction output channels. The vertical panner changes the level distribution of the sound signals in the vertical direction to produce a sound signal and outputs the produced sound signal to an output channel for the front center.

Dependencies are inferred from the claim text.
