Abstract: front page image
(EN)The present invention relates to an audio signal processing apparatus and audio signal processing method for performing binaural rendering. Provided are an audio signal processing apparatus for performing binaural filtering for an input audio signal, and an audio signal processing method using the same, the audio signal processing apparatus comprising: a first filtering unit which filters the input audio signal with a first side transfer function to generate a first side output signal; and a second filtering unit which filters the input audio signal with a second side transfer function to generate a second side output signal, wherein the first side transfer function and the second side transfer function are generated by transforming an interaural transfer function (ITF) with respect to the input audio signal.
(FR)La présente invention concerne un appareil de traitement de signal audio et un procédé de traitement de signal audio destiné à effectuer un rendu binauriculaire. L'invention concerne un appareil de traitement de signal audio destiné à effectuer un filtrage binauriculaire, et un procédé de traitement de signal audio l'utilisant, l'appareil de traitement de signal audio comprenant : une première unité de filtrage qui filtre le signal audio d'entrée avec une première fonction de transfert latérale pour générer un premier signal de sortie latéral ; et une seconde unité de filtrage qui filtre le signal audio d'entrée avec une seconde fonction de transfert latérale pour générer un second signal de sortie latéral la première fonction de transfert latérale et la seconde fonction de transfert latérale étant générées par la transformation d'une fonction de transfert interauriculaire (ITF) par rapport au signal audio d'entrée.
(KO)본 발명은 바이노럴 렌더링을 수행하기 위한 오디오 신호 처리 장치 및 오디오 신호 처리 방법에 관한 것이다. 입력 오디오 신호에 대한 바이노럴 필터링을 수행하기 위한 오디오 신호 처리 장치로서, 상기 입력 오디오 신호를 제1 측 전달 함수로 필터링하여 제1 측 출력 신호를 생성하는 제1 필터링부; 및 상기 입력 오디오 신호를 제2 측 전달 함수로 필터링하여 제2 측 출력 신호를 생성하는 제2 필터링부; 를 포함하되, 상기 제1 측 전달 함수 및 제2 측 전달 함수는 상기 입력 오디오 신호에 대한 양이간 전달 함수(Interaural Transfer Function, ITF)를 변형하여 생성되는 오디오 신호 처리 장치 및 이를 이용한 오디오 신호 처리 방법을 제공한다.
