Title
(EN) PROCESSING AUDIO DATA TO COMPENSATE FOR PARTIAL HEARING LOSS OR AN ADVERSE HEARING ENVIRONMENT
(FR) TRAITEMENT DE DONNÉES AUDIO POUR COMPENSER UNE PERTE AUDITIVE PARTIELLE OU UN ENVIRONNEMENT AUDITIF INDÉSIRABLE
Abstract
(EN)
Methods a provided for improving an audio scene for people suffering from hearing loss or for adverse hearing environments. Audio objects may be prioritized. In some implementations, audio objects that correspond to dialogue may be assigned to a highest priority level. Other implementations may involve assigning the highest priority to other types of audio objects, such as audio objects that correspond to events. During a process of dynamic range compression, higher-priority objects may be boosted more, or cut less, than lower-priority objects. Some lower-priority audio objects may fall below the threshold of human hearing, in which case the audio objects may be dropped and not rendered.
(FR)
L’invention porte sur des procédés pour améliorer une scène audio pour des personnes souffrant d’une perte auditive ou pour des environnements auditifs indésirables. Des objets audio peuvent être classés par ordre de priorité. Dans certaines mises en œuvre, des objets audio qui correspondent à un dialogue peuvent être affectés à un niveau de priorité le plus élevé. D’autres mises en œuvre peuvent consister à affecter la priorité la plus élevée à d’autres types d’objets audio, tels que des objets audio qui correspondent à des événements. Durant un processus de compression de plage dynamique, des objets de priorité plus élevée peuvent être augmentés plus, ou diminués moins, que des objets de priorité plus faible. Certains objets audio de priorité plus faible peuvent tomber sous le seuil d’audition humaine, auquel cas les objets audio peuvent être supprimés et non rendus.
