要約
(EN) This audio signal processing device is characterized by being provided with: a sound signal input unit (11) which inputs a sound signal; a position information acquisition unit (171) which acquires the position information of the sound source of the sound signal; a rotation information receiving unit (173) which receives input of rotation information; a sound source position control unit (172) which, on the basis of the rotation information, rotates the position of the sound source around a prescribed axis and changes the sound localization position of the sound source; and a localization processing unit (14) which performs localization processing on the sound signal such that sound from the sound source is localized at the sound localization position changed by the sound source position control unit (172).
(FR) L'invention concerne un dispositif de traitement de signal audio qui est caractérisé en ce qu'il comprend : une unité d'entrée de signal sonore (11) qui entre un signal sonore ; une unité d'acquisition d'informations de position (171) qui acquiert les informations de position de la source sonore du signal sonore ; une unité de réception d'informations de rotation (173) qui reçoit une entrée d'informations de rotation ; une unité de commande de position de source sonore (172) qui, sur la base des informations de rotation, fait tourner la position de la source sonore autour d'un axe prescrit et change la position de localisation sonore de la source sonore ; et une unité de traitement de localisation (14) qui effectue un traitement de localisation sur le signal sonore de sorte que le son provenant de la source sonore soit localisé au niveau de la position de localisation de son modifiée par l'unité de commande de position de source sonore (172).
(JA) オーディオ信号処理装置は、音信号を入力する音信号入力部(11)と、前記音信号の音源の位置情報を取得する位置情報取得部(171)と、回転情報の入力を受け付ける回転情報受付部(173)と、前記回転情報に基づいて、前記音源の位置を、所定軸を中心として回転させ、前記音源の音像定位位置を変更する、音源位置制御部(172)と、前記音源位置制御部(172)で変更した前記音像定位位置に前記音源の音像が定位するように、前記音信号に対して定位処理を行なう定位処理部(14)と、を備えたことを特徴とする。
