Title (EN) AUDIO CHANNEL SPATIAL TRANSLATION
(FR) TRANSLATION SPATIALE DE CANAUX AUDIO
Abstract:
(EN) M audio input channels, each associated with a spatial direction, are translated to N audio output channels, each associated with a spatial direction, wherein M and N are positive whole integers, M is three or more, and N is three or more, by deriving the N audio output channels from the M audio input channels, wherein one or more of the M audio input channels is associated with a spatial direction other than a spatial direction with which any of the N audio output channels is associated, and at least one of the one or more of the M audio input channels is mapped to a respective set of at least three of the N output channels. At least three output channels of a set may be associated with contiguous spatial directions.
(FR) Selon l'invention, M canaux d'entrée audio, associés chacun à une direction spatiale, sont translatés en N canaux de sortie audio, associés chacun à une direction spatiale, M et N étant des entiers positifs, M étant supérieur ou égal à trois et N étant supérieur ou égal à trois, par obtention des N canaux de sortie audio à partir des M canaux d'entrée audio, un ou plusieurs des M canaux d'entrée audio étant associés à une direction spatiale autre qu'une direction spatiale à laquelle n'importe lequel des N canaux de sortie audio est associé, et au moins un de ces un ou plusieurs des M canaux d'entrée audio étant fait correspondre à un ensemble respectif d'au moins trois des N canaux de sortie. Au moins trois canaux de sortie d'un ensemble peuvent être associés à des directions spatiales contiguës.
