Title (EN) FREQUENCY BAND DETERMINING METHOD FOR QUANTIZATION NOISE SHAPING AND TRANSIENT NOISE SHAPING METHOD USING THE SAME
(FR) PROCÉDÉ DE DÉTERMINATION DE LA BANDE DE FRÉQUENCE POUR LA MISE EN FORME DE LA DISTORSION DE LA QUANTIFICATION ET PROCÉDÉ DE MISE EN FORME DU BRUIT TRANSITOIRE L'UTILISANT
Abstract: front page image
(EN)A frequency band determining method for quantization noise shaping includes checking whether audio signals obtained from low-pass filtering are transient, determining a predetermined frequency band to be applied as a frequency band to be applied for quantization noise shaping when the audio signals are not transient, and determining an extended frequency band extended more than the predetermined frequency band to be applied as a frequency band to be applied when the audio signals are transient.
(FR)La présente invention concerne un procédé de détermination de la bande de fréquence pour la mise en forme de la distorsion de la quantification qui comprend les étapes consistant à vérifier si les signaux audio obtenus à partir du filtrage passe-bas sont transitoires, à déterminer une bande de fréquence prédéterminée à appliquer en tant que bande de fréquence à appliquer pour la mise en forme de la distorsion de la quantification lorsque les signaux audio ne sont pas transitoires, et à déterminer une bande de fréquence étendue s'étendant plus que la bande de fréquence prédéterminée à appliquer comme bande de fréquence à appliquer lorsque les signaux audio sont transitoires.
