Method of implementing equalizer in audio signal decoder and apparatus therefor

Abstract

A method of implementing an equalizer in an audio signal decoder and an apparatus therefor are provided. According to the method and apparatus, a signal output from an audio signal decoder is not processed by an equalizer, but the values of frequency components are adjusted according to a user's input before subband sample data is transformed into a frequency domain signal in an audio signal decoder, thereby implementing an equalizer in a codec. In this way, the complexity of implementing an apparatus for reproducing an audio signal can be reduced and delay of an equalizer can be reduced.
