음원(音源)데이터는 4비트의 적응차분(適應差分) PCM데이터의 28샘플로 이루어지는 14바이트의 사운드데이터영역 SA과, 루프정보 LP, 필터정보 FL, 시프트량 RA으로 이루어지는 사운드파라미터영역 PA으로 구성된다.
이 음원데이터의 부호화시에는, CD－ROM XA의 엔코드장치에서 엔코드처리를 행할 수 있다.
4비트의 ADPCM데이터를 BBR디코더(53)에서 디코드처리하고, 피치변환부(54)에서 피치변환하고, 엔벨로프제네레이터(58)에서 엔벨로프의 변환처리된 후에, 볼룸(60L, 60R)에서 음량조절되어 출력하는 좌우채널의 음성출력과, 믹싱볼륨(65)에서 음량조절된 16비트 PCM데이터와를 가산기(62)에서 가산한다. 또, 믹싱볼륨(65)으로부터의 음성데이터, 또는 이 음성데이터와 상기 볼륨(60L,60R)으로부터의 음성데이터와를 가산기(67)에서 가산한 가산출력이 리버브처리부(68)에서 리버브처리되고, 리버브볼륨(69)에서 음량 조절된 음성데이터와, 가산기(62)로부터의 음성데이터와 가산한다.
음원데이터와 실음데이터와를 하나의 회로내에서 용이하게 혼합할 수 있다.
