Abstract

La présente invention concerne des procédés (700, 800, 900), des systèmes (200, 300, 400, 500, 600) et des produits de programme informatique. Des métadonnées de localisation (620) associées à un objet audio sont reçues (801). Les métadonnées de localisation définissent une position de l'objet audio dans une scène audio. Il est estimé (630, 802), sur la base des métadonnées de localisation, si l'objet audio comprend un dialogue. Une valeur représentative d'un résultat de l'estimation est attribuée (803) à un paramètre de type d'objet (231). Dans certains modes de réalisation exemplaires, des objets audio sont sélectionnés (661, 662, 804) sur la base de valeurs de leurs paramètres de type d'objet respectifs. Dans certains modes de réalisation exemplaires, au moins un des objets audio sélectionnés est soumis à une accentuation de dialogue (690, 807).
