Abstract

L'invention concerne un procédé de traitement d'effet sonore et un produit associé. Le procédé consiste à : déterminer une coordonnée tridimensionnelle de chaque source sonore parmi une pluralité de sources sonores correspondant à un dispositif électronique, et des données à piste unique générées par chaque source sonore, de façon à obtenir une pluralité de premières coordonnées tridimensionnelles et une pluralité d'éléments de données à piste unique; déterminer une seconde coordonnée tridimensionnelle d'un objet cible correspondant au dispositif électronique; et, en fonction de la pluralité de premières coordonnées tridimensionnelles et de la seconde coordonnée tridimensionnelle, synthétiser la pluralité d'éléments de données à piste unique pour obtenir des données cibles à double piste. Au moyen de la présente invention, un effet de lecture de données audio peut être amélioré.
