A system and method for effectively implementing fixed masking thresholds in an audio encoder device (312) comprises a filter bank (318) for filtering source audio data (316) to produce frequency sub-bands, a lookup table (326) for storing masking threshold corresponding to the frequency sub-bands, and a bit allocator (322) for using the masking thresholds to identify and discard masked audio data to thereby reduce the total amount of audio data that requires processing.
L'invention concerne un système et un procédé permettant de mettre en oeuvre efficacement de seuils de masquage fixes dans un codeur audio (312) comprenant un banc de filtres (318) pour filtrer les données audio source (316) afin de produire des sous-bandes de fréquences, une table de recherche (326) pour stocker le seuil de masquage correspondant aux sous-bandes de fréquence, et un allocateur de bits (322) permettant d'utiliser les seuils de masquage pour identifier et ignorer les données audio masquées, ce qui réduit la quantité totale de données audio qui nécessitent un traitement.
