Abstract: front page image
(EN)An audio playback device (110) plays back an audio object containing an audio signal and playback position information that indicates a position in three-dimensional space for localizing the sound image of the audio signal, and is provided with: at least one speaker array (106); a conversion unit (102) that converts the playback position information into corrected playback position information that is position information on two-dimensional coordinate axes in which the position of the speaker array (106) is used as a reference; and a signal processing unit (105) that performs processing for localizing the sound image of the audio signal that is included in the audio object in accordance with the corrected playback position information.
(FR)L'invention concerne un dispositif de lecture audio (110) qui lit un objet audio contenant un signal audio et des informations de position de lecture qui indiquent une position dans un espace tridimensionnel pour localiser l'image de son du signal audio, et comporte : au moins un réseau de haut-parleurs (106); une unité de conversion (102) qui convertit les informations de position de lecture en informations de position de lecture corrigées qui sont des informations de position sur des axes de coordonnées bidimensionnelles dans lesquels la position du réseau de haut-parleurs (106) est utilisée comme référence; et une unité de traitement de signal (105) qui réalise un traitement pour localiser l'image de son du signal audio qui est inclus dans l'objet audio conformément aux informations de position de lecture corrigées.
(JA)オーディオ信号とその音像を定位させる3次元空間における位置を示す再生位置情報とを含むオーディオオブジェクトを再生するオーディオ再生装置(110)であって、少なくとも1体のスピーカアレー(106)と、再生位置情報を、スピーカアレー(106)の位置を基準とした2次元座標軸上の位置情報である修正再生位置情報に変換する変換部(102)と、修正再生位置情報に応じてオーディオオブジェクトに含まれるオーディオ信号の音像を定位させる処理をする信号処理部(105)とを備える。
