Title:
【発明の名称】オーディオエンコード装置において固定マスキング閾値を効果的に実現する装置及び方法
Document Type and Number:
Japanese Patent JP2002534039
Kind Code:
A
Abstract:
A system and method for effectively implementing fixed masking thresholds in an audio encoder device comprises a filter bank for filtering source audio data to produce frequency sub-bands, a lookup table for storing masking threshold corresponding to the frequency sub-bands, and a bit allocator for using the masking thresholds to identify and discard masked audio data to thereby reduce the total amount of audio data that requires processing.
