Abstract[English]
This disclosure describes a system and method for Head-Related Transfer Function (HRTF) interpolation when an HRTF dataset does not contain a particular direction associated with a desired source. The disclosed HRTF interpolation uses a finite set of HRTFs from a dataset to obtain the HRTF of any possible direction and distance, even if the direction/distance doesn't exist on the current dataset.[French]
Cette invention décrit un système et un procédé d'interpolation de la fonction de transfert liée à la tête (HRTF) lorsqu'un ensemble de données HRTF ne contient pas une direction particulière associée à une source souhaitée. L'interpolation HRTF concernée utilise un ensemble fini de HRTF d'un ensemble de données pour obtenir la HRTF de toute direction et distance possibles, même si la direction/distance n'existe pas sur l'ensemble de données actuel.
