Abstract
(EN)
An apparatus and a method for processing a multi-channel audio signal are disclosed. The method for processing a multi-channel audio signal comprises the steps of: generating audio signals of N number of channels by down-mixing audio signals of M number of channels; and generating a stereo audio signal by binaural-rendering the audio signals of the N number of channels.
(FR)
L'invention porte sur un appareil et un procédé de traitement d'un signal audio multicanal. Le procédé de traitement de signal audio multicanal comprend les étapes consistant à : générer des signaux audio d'un nombre N de canaux par mixage réducteur de signaux audio d'un nombre M de canaux ; et à générer un signal audio stéréo par rendu binaural des signaux audio du nombre N de canaux.
