Abstract[English]
and rephasing applied to one of the channels of the stereophonic signal, the method being such that a step of selecting (203b) the channel on which the rephasing is applied is carried out according to a selection criterion (203a) that depends on a value representative of an energy ratio between the channels of the stereophonic signal. The invention also relates to a processing device for reducing channels that implements the method.[French]
et une remise en phase appliquée sur un des canaux du signal stéréophonique, le procédé étant tel qu'une étape de sélection (203b) du canal sur lequel la remise en phase est appliquée, est effectuée selon un critère de sélection (203a) fonction d'une valeur représentative d'un ratio d'énergie entre les canaux du signal stéreophonique. L'invention se rapporte également à un dispositif de traitement de réduction de canaux mettant en œuvre le procédé.
