Abstract

An apparatus and method for reproducing 2-channel virtual sound while dynamically controlling sweet spot and crosstalk cancellation are disclosed. The method includes: receiving a broadband signal, setting compensation filter coefficients according to the response characteristics of the frequency band and setting a stereo transfer function according to spectrum analysis; multi-channel signal to down-mix the input multi-channel signal into a two-channel signal, eliminate the crosstalk of the down-mixed signal on the basis of the compensation filter coefficient calculated using the set stereo transfer function, and The compensation filter coefficients are set for each frequency band based on the level and phase of the compensated signal for crosstalk cancellation.

Description

[0001] This application claims priority from Korean Patent Application No. 2003-92510 filed on December 17, 2003 in the Korean Intellectual Property Office, which is hereby incorporated by reference in its entirety. technical field

[0002] The present general inventive concept relates to an audio reproducing system, and more particularly, to an apparatus and method for reproducing 2-channel virtual sound capable of dynamically controlling a sweet spot and crosstalk cancellation. Background technique

[0003] Generally, a virtual sound reproduction system provides a surround sound effect similar to a 5.1-channel system, but uses only two speakers.

[0004] The technology related to the virtual sound reproduction system is disclosed in WO 99 / 49574 (PCT / AU99 / 00002 applied on January 6, 1999, titled: audio signal processing method and device (AUDIO SIGNAL PROCESSING METHOD AND APPARATUS)) and WO97 / 30566 (PCT / GB97 / 00415 was appli...
