Abstract

본 발명은 디지탈 오디오 부호화기의 마스킹 임계값 결정 방법에 관한 것으로 일정 주파수 이상에 대해서는 마스킹 임계값을 계산하지 않고 절대 가청 임계값을 마스킹 임계값으로 결정함으로써 마스킹 임계값의 계산량을 줄일 수 있는 것이다.The present invention relates to a method for determining a masking threshold of a digital audio encoder, and the calculation amount of the masking threshold can be reduced by determining the absolute audible threshold as the masking threshold without calculating the masking threshold for a predetermined frequency or more.
