Title (EN) SIGNAL PROCESSING DEVICE, METHOD, AND PROGRAM
(FR) DISPOSITIF DE TRAITEMENT DE SIGNAL, PROCÉDÉ ET PROGRAMME
(JA) 信号処理装置および方法、並びにプログラム
Abstract:
(EN) The present invention pertains to a signal processing device, method, and program whereby different audio can be played back in distant and near locations. The signal processing device comprises: a distant filter unit that generates distant audio playback signals for playing back audio in a distant listening area, generating same by filtering first audio source signals using a distant audio playback filter coefficient; and a near filter unit that generates near audio playback signals for playing back audio in a near listening area different from the distant listening area, generating same by filtering second audio source signals using a near audio playback filter coefficient. This technology can be applied to a near/distant-separated audio field-forming device.
(FR) La présente invention concerne un dispositif, un procédé et un programme de traitement de signal permettant de lire différentes données audio dans des emplacements distants et proches. Le dispositif de traitement de signal comprend : une unité de filtre distant générant des signaux de lecture audio distants pour lire une donnée audio dans une zone d'écoute distante, la génération de cette dernière par filtrage de premiers signaux de source audio à l'aide d'un coefficient de filtre de lecture audio distant; et une unité de filtre proche générant des signaux de lecture audio proches afin de lire une donnée audio dans une zone d'écoute proche différente de la zone d'écoute distante, générant cette dernière en filtrant des seconds signaux de source audio à l'aide d'un coefficient de filtre de lecture audio proche. Cette technologie peut être appliquée à un dispositif de formation de champ audio proche/distant séparé.
(JA) 本技術は、遠方と近傍とで異なる音を再生することができるようにする信号処理装置および方法、並びにプログラムに関する。 信号処理装置は、第1の音源信号に対して遠方音再生フィルタ係数を用いたフィルタ処理を行うことで、遠方受聴領域で音を再生するための遠方音再生信号を生成する遠方フィルタ部と、第2の音源信号に対して近傍音再生フィルタ係数を用いたフィルタ処理を行うことで、遠方受聴領域とは異なる近傍受聴領域で音を再生するための近傍音再生信号を生成する近傍フィルタ部とを備える。本技術は遠近別音場形成装置に適用することができる。
