Abstract
(EN)
This audio device is provided with: a first path in which digital-sigma modulation is applied to a sound source signal or a signal generated on the basis of the sound source signal; a second path in which digital-sigma modulation is not applied to a DSD sound source signal or a signal generated on the basis of the DSD sound source signal; a synthesis unit which synthesizes the signal from the first path and the signal from the second path; and an output unit which outputs the signal synthesized by the synthesis unit.
(FR)
L'invention concerne un dispositif audio qui comporte : un premier trajet dans lequel une modulation numérique-sigma est appliquée à un signal de source sonore défini arbitraire ou à un signal généré sur la base du signal de source sonore défini arbitraire; un second trajet dans lequel aucune modulation numérique-sigma n'est appliquée à un signal de source sonore DSD ou à un signal généré sur la base du signal de source sonore DSD; une unité de synthèse qui synthétise le signal provenant du premier trajet et le signal provenant du second trajet; et une unité de sortie qui délivre en sortie le signal synthétisé par l'unité de synthèse.
(JA)
任意の音源信号、もしくは、任意の音源信号に基づき生成された信号にデルタシグマ変調を行う第1の経路と、DSD音源信号、もしくは、DSD音源信号に基づき生成された信号にデルタシグマ変調を行わない第2の経路と、第1の経路からの信号と、第2の経路からの信号を合成する合成部と、合成部で合成された信号を出力する出力部と、を備えたオーディオ装置である。
