Title (EN) A METHOD AND APPARATUS FOR PERFORMING AN ADAPTIVE DOWN- AND UP-MIXING OF A MULTI-CHANNEL AUDIO SIGNAL
(FR) PROCÉDÉ ET APPAREIL PERMETTANT D'EFFECTUER UN SOUS ET UN SUR-MIXAGE ADAPTATIF D'UN SIGNAL AUDIO MULTICANAL
Abstract: front page image
(EN)A method and apparatus for performing an adaptive down-mixing of a multichannel audio signal comprising a number of input channels,wherein a signal adaptive transformation of said input channels is performed by multiplying the input channels with a downmix block matrix comprising a fixed block for providing a set of backward compatible primary channels and a signal adaptive block for providing a set of secondary channels.
(FR)Procédé et appareil permettant d'effectuer une opération de sous-mixage adaptatif d'un signal audio multicanal comprenant un certain nombre de canaux d'entrée, dans lequel la transformation adaptative d'un signal desdits canaux d'entrée est effectuée en multipliant les canaux d'entrée avec une matrice de bloc de sous-mixage comprenant un bloc fixe pour fournir un ensemble de canaux primaires rétrocompatibles et un bloc adaptatif de signal pour fournir un ensemble de canaux secondaires.
