Title (EN) AUDIO SIGNAL PROCESSING DEVICE
(FR) DISPOSITIF DE TRAITEMENT DE SIGNAL AUDIO
(JA) 音声信号処理装置
Abstract:
(EN) Provided is an audio signal processing device, whereby a multiplexed audio input signal is converted by a plurality of array speakers to a playable format, comprising: a down-mix processing unit which splits the multiplexed audio signal and carries out a down-mixing of each of the plurality of audio input signals obtained thereby; a virtual sound source setting unit which treats each of the audio input signals which are down-mixed with the down-mix processing unit as signals from each of at least two virtual sound sources and applies location information to the virtual sound sources; and a wave field synthesis processing unit which generates output signals from each of the array speakers on the basis of location relations between the generated virtual sound sources and each of the speakers of the array speakers.
(FR) La présente invention porte sur un dispositif de traitement de signal audio, par lequel un signal d'entrée audio multiplexé est converti par une pluralité de haut-parleurs en groupement en un format pouvant être reproduit, comprenant : une unité de traitement de mixage réducteur qui divise le signal audio multiplexé et réalise un mixage réducteur de chaque signal d'entrée audio de la pluralité de signaux d'entrée audio ainsi obtenus; une unité de réglage de sources sonores virtuelles qui considère chacun des signaux d'entrée audio qui sont soumis au mixage réducteur par l'unité de traitement de mixage réducteur comme étant un signal provenant de chacune d'au moins deux sources sonores virtuelles et applique des informations de position aux sources sonores virtuelles; et une unité de traitement de synthèse de champ d'ondes qui génère des signaux de sortie à partir de chacun des haut-parleurs en groupement sur la base de relations de position entre les sources sonores virtuelles générées et chacun des haut-parleurs des haut-parleurs en groupement.
(JA)  多重化された音声入力信号を複数のアレイスピーカによって再生可能な方式に変換する音声信号処理装置であって、前記多重化された音声信号を分離して得られた複数の音声入力信号の各々のダウンミックスを行うダウンミックス処理部と、前記ダウンミックス処理部でダウンミックスされた音声入力信号の各々を少なくとも2つの仮想音源のそれぞれからの信号とみなし、前記仮想音源に位置情報を与える仮想音源設定部と、生成された前記仮想音源とアレイスピーカのスピーカ各々の位置関係とに基づいて、前記アレイスピーカの各々からの出力信号を生成する波面合成処理部と、を備えることを特徴とする音声信号処理装置。
