Abstract
(EN)
A method for controlling an audio signal may comprise the steps of: identifying, through an audio zoom effect field included in metadata, whether an audio zoom effect on at least one acoustic object existing in virtual reality is being used; and, when it is identified that the audio zoom effect is being used, controlling the audio signal corresponding to the acoustic object on the basis of a preset method.
(FR)
L'invention concerne un procédé de commande d'un signal audio qui peut comprendre les étapes consistant : à déterminer, par l'intermédiaire d'un champ d'effet de zoom audio inclus dans des métadonnées, si un effet de zoom audio sur au moins un objet acoustique existant dans une réalité virtuelle est utilisé ; et, lorsqu'il est déterminé que l'effet de zoom audio est utilisé, à commander le signal audio correspondant à l'objet acoustique sur la base d'un procédé prédéfini.

음향 신호 제어 방법은, 메타데이터에 포함된 음향 확대 효과 필드를 통해, 가상 현실에 존재하는 적어도 하나의 음향 객체에 대한 음향 확대 효과(audio zooming effect) 사용 여부를 식별하는 단계; 및 상기 음향 확대 효과(audio zooming effect)가 사용되는 것으로 식별된 경우, 상기 음향 객체에 대응하는 음향 신호를 미리 설정된 방법에 기초하여 제어하는 단계를 포함할 수 있다.
