Abstract
(EN)
A method comprising: obtaining at least two audio signals for reproduction, each of the at least two audio signals associated with a respective one of at least two reproduction locations (211, 213, 215, 231, 233) within an audio reproduction space; obtaining within the audio reproduction space at least two zones (220, 221, 223); obtaining at least one location for a user's (201) position within the audio reproduction space, the at least one location being relative to at least one of the at least two zones (220, 221, 223) and the at least two reproduction locations (211, 213, 215, 231, 233); and processing the at least two audio signals based on the obtained at least one location for the user's (201) position within the audio reproduction space to generate at least one output audio signal, the at least one output audio signal is reproduced from at least one of the at least two reproduction locations (211, 213, 215, 231, 233).
(FR)
La présente invention concerne un procédé comprenant : l'obtention d'au moins deux signaux audio pour la reproduction, chacun des au moins deux signaux audio étant associé à un emplacement respectif parmi au moins deux emplacements de reproduction (211, 213, 215, 231, 233) dans un espace de reproduction audio ; l'obtention dans l'espace de reproduction audio d'au moins deux zones (220, 221, 223) ; l'obtention d'au moins un emplacement pour la position d'un utilisateur (201) dans l'espace de reproduction audio, ledit au moins un emplacement étant associé à au moins une des au moins deux zones (220, 221, 223) et aux au moins deux emplacements de reproduction (211, 213, 215, 231, 233) ; et le traitement des au moins deux signaux audio sur la base de l'au moins un emplacement obtenu pour la position de l'utilisateur (201) dans l'espace de reproduction audio afin de générer au moins un signal audio de sortie, l'au moins un signal audio de sortie étant reproduit à partir d'au moins un des au moins deux emplacements de reproduction (211, 213, 215, 231, 233).
