Abstract
(EN) The present technique pertains to a signal processing device and method, and a program capable of more effectively controlling the sense of distance. The signal processing device includes a reverberation processing unit for generating a signal for a reverberation component on the basis of object audio data for an audio object and reverberation parameters for the audio object. The present technology can be applied to a signal processing device.
(FR) La présente invention concerne un dispositif et un procédé de traitement de signal ainsi qu'un programme pouvant commander plus efficacement la perception de distance. Le dispositif de traitement de signal comprend une unité de traitement de réverbération destinée à générer un signal pour une composante de réverbération sur la base de données audio d'objet pour un objet audio et de paramètres de réverbération pour l'objet audio. La présente invention peut être appliquée à un dispositif de traitement de signal.
