A method and apparatus used for determining phasing correlation between left-channel and right-channel signals of a stereophonic audio signal is provided. The determination of the phase correlation is facilitated by deriving centrally localized components contained in the audio signal to provide an indication representative of phase correlation existing between the left-channel and right-channel signals.
L'invention est constituée par une méthode et un appareil servant à déterminer les corrélations de phase entre les signaux des canaux gauche et droit dans un signal audio stéréophonique. La détermination des corrélations de phase est facilitée par la dérivation des composantes localisées contenues centralement dans le signal audio pour donner une indication représentative de la corrélation de phase entre les signaux des canaux gauche et droit.
