Title (EN) SIGNAL PROCESSING DEVICE, METHOD, AND PROGRAM
(FR) DISPOSITIF, PROCÉDÉ ET PROGRAMME DE TRAITEMENT DE SIGNAL
(JA) 信号処理装置および方法、並びにプログラム
Abstract:
(EN) The present technique pertains to a signal processing device, method, and program configured so that it is possible to reduce calculation load. The signal processing device comprises an ambisonic gain calculation unit that derives ambisonic gain when an object is in a prescribed position, on the basis of spread information for the object. The present technique can be applied to an encoder and a decoder.
(FR) L'invention concerne un dispositif, un procédé et un programme de traitement de signal configurés de façon à pouvoir réduire la charge de calcul. Le dispositif de traitement de signal comprend une unité de calcul de gain ambiophonique qui dérive un gain ambiophonique lorsqu'un objet est dans une position prescrite d'après les informations d'étalement de l'objet. L'invention peut s'appliquer à un codeur et à un décodeur.
(JA) 本技術は、計算負荷を低減させ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、オブジェクトのスプレッド情報に基づいて、オブジェクトが所定の位置にあるときのアンビソニックゲインを求めるアンビソニックゲイン計算部を備える。本技術はエンコーダおよびデコーダに適用することができる。
