Abstract

본 발명은, 오디오 신호의 현재 프레임에 대해서 선형-예측 분석을 수행함으로써, 복수의 선형-예측 변환 계수들을 근거로 하여 제 1단계의 타깃 벡터인 제 1 타깃 벡터를 생성하는 단계; 상기 제 1 타깃 벡터를 벡터 양자화함으로써, 임시로 결정된 개수의 제 1 단계의 제 1 임시 후보 코드벡터들을 획득하는 단계; 상기 제 1 임시 후보 코드벡터들 및 상기 제 1 타깃 벡터간의 에러인 제 1 임시 후보 에러들을 산출하는 단계; 및, 상기 제 1 임시 후보 에러들을 근거로 하여 제 1 후보 코드벡터들의 개수인 제 1 개수를 결정하고, 상기 제 1 개수만큼의 제 1 최종 후보 코드벡터들을 획득하는 단계를 포함하는 오디오 신호 처리 방법을 개시한다.
