Abstract
La présente demande divulgue un procédé et un appareil de traitement audio et un dispositif électronique. Le procédé consiste : à effectuer un traitement d'augmentation de résolution sur un premier signal audio pour obtenir un second signal audio ; à effectuer un traitement de filtrage passe-bas sur le second signal audio pour obtenir un second signal audio traité ; à effectuer un traitement de signal sur le second signal audio traité pour obtenir Y premiers signaux de sous-bande ayant la même largeur de bande ; selon les signaux de sous-bande basse fréquence parmi les Y premiers signaux de sous-bande, à générer M signaux de sous-bande haute fréquence ; sur la base des informations de caractéristique haute fréquence du premier signal audio, à effectuer un ajustement de spectre sur les M signaux de sous-bande haute fréquence pour obtenir M signaux de sous-bande haute fréquence cibles ; et à synthétiser les M signaux de sous-bande haute fréquence cibles pour obtenir un signal audio cible ; Y et M étant des nombres entiers positifs.
