摘要： Provided is a method and apparatus for focusing sound using an array speaker system. The method includes generating a plurality of delayed signals to be focused to a predetermined position from an input signal, filtering a low-frequency signal having a frequency that is lower than a reference frequency from the delayed signals, generating low-frequency focusing signals divided into 2 groups by adjusting a gain of the filtered low-frequency signal, and applying the low-frequency focusing signals divided into the 2 groups to speaker units of the array speaker system at both sides with respect to a center portion of the array speaker system and outputting the low-frequency focusing signals through the speaker units. In this way, the performance of sound focusing for the low-frequency signal can be improved and thus a listener located a predetermined distance from and in a predetermined direction relative to the array speaker system can clearly listen to the low-frequency focusing signals.

摘要： A method and apparatus for localizing a sound image of an input signal to a spatial position are provided. The method of localizing a sound image to a spatial position includes: extracting from a head related impulse response (HRIR) measured with respect to changes in the position of a sound source, first information indicating a reflection sound wave reflected by the body of a listener; extracting from the HRIR second information indicating the difference between sound pressures generated in two ears, respectively, when a direct sound wave generated from the position of the sound source arrives at the two ears, respectively, of the listener; extracting third information indicating the difference between times taken by the direct sound wave to arrive at the two ears, respectively, from the HRIR; and localizing a sound image of an input signal to a spatial position by using the extracted information. According to the method and apparatus of the present invention, by using only important information having influence on sound image localization of a virtual sound source extracted from the HRIR, the sound image of the input signal can be localized to a spatial position with a small number of filter coefficients.
