(JA) 収音装置および収音方法
Abstract:
(EN) This sound acquisition device is characterized by being provided with a plurality of microphones, a plurality of first gain control units that control the respective gains of the microphones, an addition unit that performs, by using a prescribed gain, addition on sound signals outputted by the respective first gain control units, a second gain control unit that controls the gain of the sound signal outputted by the addition unit, and a gain setting unit that sets the respective gains of the plurality of first gain control units on the basis of the gain setting at the second gain control unit.
(FR) La présente invention concerne un dispositif d'acquisition de son caractérisé en ce qu'il est muni d'une pluralité de microphones, d'une pluralité de premières unités de commande de gain qui commandent les gains respectifs des microphones, une unité d'addition qui effectue, en utilisant un gain prescrit, une addition sur des signaux de son délivrés par les premières unités respectives de commande de gain, une deuxième unité de commande de gain qui commande le gain du signal de son délivré par l'unité d'addition, et une unité de réglage de gain qui règle les gains respectifs de la pluralité de premières unités de commande de gain sur la base du réglage de gain au niveau de la deuxième unité de commande de gain.
(JA)  収音装置は、複数のマイクと、各マイクのゲイン制御をそれぞれ行う複数の第1ゲイン制御部と、各第1ゲイン制御部から出力される音声信号をそれぞれ所定のゲインで加算する加算部と、前記加算部から出力される音声信号のゲイン制御を行う第2ゲイン制御部と、前記第2ゲイン制御部におけるゲイン設定に基づいて、前記複数の第1ゲイン制御部のそれぞれのゲイン設定を行うゲイン設定部と、を備えたことを特徴とする。
