音像定位装置
Document Type and Number:
Japanese Patent JP4594662
Kind Code:
B2
Abstract:
Multiple independent sound images are formed to enable a user to listen thereto, in a simple configuration. By integrally performing uncorrelation processing and sound image localization processing on an input audio signal with signal processing means 11L and 11R, with the use of a pair of output functions hl(x) and hr(x) obtained by integrating an uncorrelation function for generating multiple audio signals with low mutual correlation from an input audio signal SA and a sound image localization function for localizing the sound image of each of the multiple audio signals at a given sound source position, it is possible to form multiple independent sound images to enable a user to listen thereto, in a simple configuration.
