Claims (2)

  1. 스테레오의 입력 L, R 채널의 차신호를 출력하는 감산수단과, 상기 감산수단의 출력으로부터 소정 대역의 주파수 성분만을 통과시키는 동시에 이 주파수 성분의 이득을 임의로 변화시키는 대역통과 가변이득수단과, 상기 대역통과 가변이득수단의 출력을 각각 상기 입력 L, R 채널의 신호에 가산하는 가산수단으로 이루어지는 것을 특징으로 하는 음향부가회로.
  2. 제1항에 있어서, 상기 대역통과 가변이득수단으로는 고주파수 대역과 저주파수 대역의 성분을 통과시키는 동시에 이들 주파수성분의 이득을 각각 임의로 변환시키도록 한 것을 특징으로 하는 음향부가회로.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
