Title (EN) AUDIO SIGNAL PROCESSING METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT DE SIGNAL AUDIO
(KO) 오디오 신호 처리 방법 및 장치
Abstract:
(EN) An audio signal processing device comprises a processor for outputting an output audio signal generated on the basis of an input audio signal. The processor can acquire information related to an input audio signal and a virtual space in which the input audio signal is simulated, can determine whether a blocking object, which performs blocking between a sound source and a listener, exists among a plurality of objects, on the basis of the position of each of the plurality of objects included in the virtual space and the position of the sound source corresponding to the input audio signal, with respect to the listener in the virtual space, and can binaurally render the input audio signal on the basis of the determination result so as to generate an output audio signal.
(FR) Selon l'invention, un dispositif de traitement de signal audio comprend un processeur permettant de fournir en sortie un signal audio de sortie produit en fonction d'un signal audio d'entrée. Le processeur peut acquérir des informations concernant un signal audio d'entrée et un espace virtuel dans lequel le signal audio d'entrée est simulé, peut déterminer si un objet bloquant, qui effectue un blocage entre une source sonore et un auditeur, existe parmi une pluralité d'objets, en fonction de la position de chaque objet de la pluralité d'objets présents dans l'espace virtuel et de la position de la source sonore correspondant au signal audio d'entrée, par rapport à l'auditeur dans l'espace virtuel, et peut restituer de manière binaurale le signal audio d'entrée en fonction du résultat de détermination de façon à produire un signal audio de sortie.
(KO) 오디오 신호 처리 장치는 입력 오디오 신호를 기초로 생성된 출력 오디오 신호를 출력하는 프로세서를 포함한다. 상기 프로세서는, 입력 오디오 신호 및 상기 입력 오디오 신호가 시뮬레이션되는 가상의 공간에 관한 정보를 획득하고, 상기 가상의 공간의 청취자를 기준으로 하는, 상기 가상의 공간에 포함된 복수의 오브젝트 각각의 위치 및 상기 입력 오디오 신호에 대응하는 음원의 위치를 기초로, 상기 복수의 오브젝트 중에서 상기 음원과 상기 청취자 사이를 가로막는 블로킹 오브젝트가 존재하는지 판단하고, 상기 판단 결과를 기초로 상기 입력 오디오 신호를 바이노럴 렌더링하여 출력 오디오 신호를 생성할 수 있다.
