Abstract

L'invention concerne un appareil et un procédé d'optimisation du son en direct, l'appareil comprenant un émetteur acoustique et un récepteur acoustique. L'émetteur acoustique est situé à proximité d'une source sonore et conçu pour recueillir des sons provenant de la source sonore et envoyer les données sonores recueillies au récepteur acoustique. Le récepteur acoustique est situé à l'intérieur d'un équipement terminal d'un utilisateur et conçu pour recevoir des données sonores envoyées par une unité de transmission de son, optimiser les données sonores et envoyer le son optimisé à l'utilisateur. Par l'intermédiaire de l'émetteur acoustique situé à proximité d'une source sonore et du récepteur acoustique situé dans l'équipement terminal de l'utilisateur, la solution technique précitée peut transférer un son clair et plein en direct vers les oreilles de l'utilisateur, conserver l'état d'origine du son, et permettre à l'utilisateur de recevoir le son avec une haute fidélité. La solution technique précitée utilise une fonction multimédia de l'équiment terminal pour transférer le son en direct, et est de faible coût car aucun autre dispositif de réception du son n'est nécessaire.
