Abstract

La divulgation porte sur un procédé de traitement d’un signal audio (100) pour un système audio d’un véhicule pour la reproduction d’un effet acoustique simulant la lecture d’un disque vinyle par un tourne-disque, ledit procédé comprenant au moins une des opérations (105) suivantes : - appliquer un filtre passe-bas numérique (101) au signal audio (100) ; - remplacer pendant une durée limitée et de façon réitérée au moins une partie du signal audio (100) par un premier filtre numérique comprenant une amplitude et une phase (102) ; - ajouter pendant une durée limitée et de façon réitérée au signal audio (100) au moins un deuxième filtre numérique comprenant une amplitude et une phase (103) ; dans lequel le signal audio est un signal audio stéréo et dans lequel le procédé est mis en œuvre dans un système stéréo comprenant au moins deux canaux audio.
