Title
(EN) CANCELLATION OF SPATIAL PROCESSING IN HEADPHONES
(FR) ANNULATION DE TRAITEMENT SPATIAL DANS DES ÉCOUTEURS
Abstract
(EN) In example implementations, an apparatus is provided. The apparatus includes a communication interface, a correlation analysis device, and a processor. The communication interface is to receive an audio signal from headphones connected to the communication interface. The correlation analysis device is to detect spatial processing applied to the audio signal from the headphones and to identify a spatial filter applied by the headphones to perform the spatial processing. The processor is to apply a correction filter to cancel the spatial processing applied by the spatial filter of the headphones and apply a spatial filter of a host to the audio signal.
(FR) Selon des modes de réalisation donnés à titre d'exemple, la présente invention concerne un appareil. L'appareil comprend une interface de communication, un dispositif d'analyse de corrélation et un processeur. L'interface de communication est destinée à recevoir un signal audio provenant d'écouteurs connectés à l'interface de communication. Le dispositif d'analyse de corrélation est destiné à détecter un traitement spatial appliqué au signal audio provenant des écouteurs et à identifier un filtre spatial appliqué par les écouteurs pour effectuer le traitement spatial. Le processeur est destiné à appliquer un filtre de correction pour annuler le traitement spatial appliqué par le filtre spatial des écouteurs et appliquer un filtre spatial d'un hôte au signal audio.
