Abstract

Σε μια μέθοδο και συσκευή μετεπεξεργασίας αποκωδικοποιημένου ηχητικού σήματος όσον αφορά τη βελτίωση της εκλαμβανόμενης ποιότητας αυτού του αποκωδικοποιημένου ηχητικού σήματος, το αποκωδικοποιημένο ηχητικό σήμα διαιρείται σε πλήθος σημάτων υποζώνης συχνοτήτων, και πραγματοποιείται μετεπεξεργασία σε τουλάχιστον ένα από τα σήματα υποζώνης συχνοτήτων. Μετά τη μετεπεξεργασία αυτού του τουλάχιστον ενός σήματος υποζώνης συχνοτήτων, τα σήματα υποζώνης συχνοτήτων είναι δυνατόν να αθροίζονται για να παράγεται ένα μετεπεξεργασμένο αποκωδικοποιημένο ηχητικό σήμα εξόδου. Με τον τρόπο αυτό, η μετεπεξεργασία μπορεί να εντοπίζεται σε μια επιθυμητή υποζώνη ή υποζώνες, ενώ οι άλλες υποζώνες παραμένουν ουσιαστικά αμετάβλητες.
