Title (EN) RECORDING AND RENDERING SPATIAL AUDIO SIGNALS
(FR) ENREGISTREMENT ET RESTITUTION DE SIGNAUX AUDIO SPATIAUX
Abstract:
(EN) Examples of the disclosure relate to a method, apparatus and computer program, the method comprising:obtaining audio signals wherein the audio signals represent spatial sound and can be used to render spatial audio using linear methods;obtaining spatial metadata corresponding to the spatial sound represented by the audio signals; and associating the spatial metadata with the obtained audio signals so that in a first rendering context the obtained audio signals can be rendered without using the spatial metadata and in a second rendering context the obtained audio signals can be rendered with using the spatial metadata.
(FR) Des exemples de la présente invention concernent un procédé, un appareil et un programme informatique, le procédé comprenant : l’obtention de signaux audio, les signaux audio représentant un son spatial et pouvant être utilisés pour restituer un contenu audio spatial au moyen de procédés linéaires ; l’obtention de métadonnées spatiales correspondant au son spatial représenté par les signaux audio ; et l’association des métadonnées spatiales aux signaux audio obtenus de sorte que, dans un premier contexte de restitution, les signaux audio obtenus peuvent être restitués sans utiliser les métadonnées spatiales et, dans un deuxième contexte de restitution, les signaux audio obtenus peuvent être restitués au moyen des métadonnées spatiales.
