Title (EN) AUDIO OBJECT CLASSIFICATION BASED ON LOCATION METADATA
(FR) CLASSIFICATION D’OBJET AUDIO SUR LA BASE DE MÉTADONNÉES DE LOCALISATION
Abstract:
(EN) Methods (700, 800, 900), systems (200, 300, 400, 500, 600) and computer program products are provided. Location metadata (620) associated with an audio object is received (801). The location metadata defines a position of the audio object in an audio scene. It is estimated (630, 802), based on the location metadata, whether the audio object includes dialog. A value representative of a result of the estimation is assigned (803) to an object type parameter (231). In some example embodiments, audio objects are selected (661, 662, 804) based on values of their respective of object type parameters. In some example embodiments, at least one of the selected audio objects is submitted to dialog enhancement (690, 807).
(FR) 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).
