Abstract

본 발명은 오디오 신호를 보다 높은 효율로 압축 및 복원할 수 있는 인코딩 신호 처리 방법 및 장치를 제공하는 것을 목적으로 한다. 이를 위한 본 발명의 오디오 신호 처리 방법의 실시예는, 제1 타입정보를 이용하여 오디오 신호의 코딩타입이 음악신호 코딩타입인지를 식별하는 단계, 상기 오디오 신호의 코딩타입이 음악신호 코딩타입이 아닌 경우, 제 2 타입정보를 이용하여 상기 오디오 신호의 코딩타입이 음성신호 코딩타입인지, 혼합신호 코딩타입인지를 식별하는 단계, 상기 오디오 신호의 코딩타입이 혼합신호 코딩타입인 경우, 상기 오디오 신호로부터 스펙트럴 데이터와 선형예측 계수를 추출하는 단계, 상기 스펙트럴 데이터를 역 주파수 변환하여 선형 예측에 대한 레지듀얼 신호를 생성하는 단계, 상기 선형예측 계수 및 상기 레지듀얼 신호를 선형 예측 코딩하여, 오디오 신호를 복원하는 단계 및 상기 복원된 오디오 신호의 일부 영역인 확장 기초 신호 및 대역 확장 정보를 이용하여 고주파 영역 신호를 복원하는 단계를 포함한다. 이를 통하여, 보다 높은 효율로 다양한 종류의 오디오 신호를 부호 및 복호할 수 있게 된다.
