Embodiment Construction

[0029] Reference will now be made in detail to embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0030] figure 2 A stereo sound generator for a stereo sound reproduction system according to one embodiment of the present general inventive concept is illustrated. refer to figure 2, the multi-channel audio signal 100 includes: a left channel signal (L), a center channel signal (C), a low-frequency effect channel signal (LFE), a right channel signal (R), a left surround channel signal (Ls ), and the right surround channel signal (Rs). A 5.1-channel system is described in this embodiment, but the present general inventive concept can be applied to a multi-channel system such as a 6.1-channel system or a 7.1-channel system...

Abstract

A method and apparatus to reproduce stereo sound, which generates optimal stereo sound designed for individual auditory properties. The method includes generating a one or more virtual surround filters corresponding to each of a plurality of head-related transfer functions (HRTFs) classified according to one or more individual auditory properties, generating stereo sound for the one or more virtual surround filters, and selecting at least one from the one or more virtual surround filters, and reproducing the stereo sound based on a filter value of the selected at least one virtual surround filter.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Patent Application No. 10-2006-0134983 filed with the Korean Intellectual Property Office on December 27, 2006, the contents of which are incorporated herein by reference. technical field [0003] The present general inventive concept relates to a stereophonic sound reproducing system, and more particularly, to a method and apparatus for reproducing stereophonic sound, which generate optimal stereophonic sound designed for individual auditory characteristics. Background technique [0004] Generally, a virtual sound generating system utilizes only two speakers to provide surround sound effects such as a 5.1-channel system. [0005] Techniques related to this virtual sound generation are disclosed in WO 99 / 49574 (PCT / AU / 00002, filed January 6, 1999, entitled "AudioSignal Processing Method and Apparatus"). [0006] In a conventional virtual sound generation system, a head-related tra...
