Title: (DE) VORRICHTUNG UND VERFAHREN ZUM VERARBEITEN EINES AUDIOSIGNALS
(EN) APPARATUS AND METHOD OF PROCESSING AN AUDIO SIGNAL
(FR) APPAREIL ET PROCEDE DE TRAITEMENT D'UN SIGNAL AUDIO
Abstract:
(EN) In one embodiment, at least one channel in a frame of the audio signal is subdivided into a plurality of blocks such that at least two of the blocks having different lengths. A length of the frame is a user defined value and is determined within a predetermined value. Furthermore, information indicating the subdivision of the channel into the blocks is generated.
(FR) L'invention concerne, dans un mode de réalisation, au moins un canal dans une trame du signal audio qui est subdivisé en plusieurs blocs de sorte qu'au moins deux de ces blocs présentent des longueurs différentes. Une longueur de la trame, valeur définie par l'utilisateur, est déterminée dans une valeur prédéterminée. De plus, des informations indiquant la subdivision du canal en blocs sont générées.
