Abstract
(EN)
Disclosed in the present application is a stereo sound playback method, comprising: extracting a stereo sound signal having orientation information from within an audio signal; decoding the stereo sound signal so as to obtain a multi-channel signal; transcoding the multi-channel signal into dual channel signals; eliminating crosstalk for the dual channel signals respectively, and outputting same to dual speakers for playback. Further provided by the present application are a stereo sound playback device, storage medium and electronic device.
(FR)
La présente invention concerne un procédé de lecture de son stéréo, consistant : à extraire un signal sonore stéréo ayant des informations d'orientation de l'intérieur d'un signal audio ; à décoder le signal sonore stéréo de façon à obtenir un signal multicanal ; à transcoder le signal multicanal en signaux à deux canaux ; à éliminer la diaphonie des signaux à deux canaux respectivement, et à les fournir à des haut-parleurs doubles pour lecture. La présente invention concerne en outre un dispositif de lecture de son stéréo, un support d'informations et un dispositif électronique.
