Title
(EN) PROCESSING METHOD OF AUDIO SIGNAL AND ELECTRONIC DEVICE SUPPORTING THE SAME
(FR) PROCÉDÉ DE TRAITEMENT DE SIGNAL AUDIO ET DISPOSITIF ÉLECTRONIQUE POUR LE PRENDRE EN CHARGE
Abstract
(EN)
According to an embodiment, the above-described specification discloses an electronic device comprises at least one processor configured to: receive a first audio signal and a second audio signal; detect a spectral envelope signal from the first audio signal and extract a feature point from the second audio signal; extend a high-band of the second audio signal based on the spectral envelope signal from the first audio signal and the feature point from the second audio signal to generate a high-band extension signal; and mix the high-band extension signal and the first audio signal, thereby resulting in a synthesized signal.
(FR)
Selon un mode de réalisation, la spécification décrite ci-dessus décrit un dispositif électronique qui comprend au moins un processeur configuré pour: recevoir un premier signal audio et un second signal audio; détecter un signal d'enveloppe spectrale à partir du premier signal audio et extraire un point caractéristique du second signal audio; étendre une bande haute du second signal audio sur la base du signal d'enveloppe spectrale provenant du premier signal audio et du point caractéristique à partir du second signal audio pour générer un signal d'extension de bande haute; et mélanger le signal d'extension de bande haute et le premier signal audio, ce qui permet d'obtenir un signal synthétisé.
