본 발명에서는, 가상적인 입체 음향을 사용자가 지정한 위치에서 재생시키기 방위각 코드에 대응하는 HRTF(Head Related Transfer Function)를 단말기용 코드북에서 검색한 후, 검색한 코드북 인덱스와 방위각 코드를 매핑시켜 인덱스 테이블을 구성한다. 이후, 매핑시킨 코드북 인덱스에 따라 HRTF 데이터를 복호화하여 재구성한 후, 재구성한 HRTF 데이터를 입력 신호인 모노 신호와 컨볼루션(CONVOLUTION) 연산하여 지정한 위치에서 가상적인 입체 음향이 재생되도록 한다.
즉, 본 발명은 외부로부터 수신한 방위각 코드에 대응하는 HRTF 데이터를 부호화한 뒤 코드북 인덱스와 방위각 코드를 인텍스화 하여 테이블에 저장 및 관리한다. 이는 곧, 메모리의 저장 용량을 대폭 감소시킬 수 있다.-

Abstract: PURPOSE: An apparatus for reproducing a multi-channel stereo sound and a method for the same are provided to prevent the power consumption due to the reduction of the calculation amount as well as to reduce the deterioration of the sound quality. CONSTITUTION: An apparatus(100) for reproducing a multi-channel stereo sound includes a main controller(120), a threshold setting block(130), a threshold resetting block(140), a signal level measuring block(150), a stereo sound signal processing block(160), a signal synthesizing block(170) and an audio output block(180). The main controller(120) synthesizes the multi-channel audio data inputted from outside with at least two audio data in response to the measured noise level and the selection of the user to reproduce. The threshold setting block(130) sets a threshold value in response to the selection of the user. The threshold resetting block(140) resets the threshold value based on the measured noise level in response to the update of the user. The signal level measuring block(150) measures the signal levels of each multi-channel audio data inputted from the outside. The stereo sound signal processing block(160) processes the inputted audio data as a stereo sound in response to the measured signal level and the reset threshold. The signal synthesizing block(170) synthesizes the signal processed multi-channel data as an audio data having at least two channels. And, the audio output block(180) outputs the synthesized audio data to outside.
