Abstract

본 발명은 오디오신호의 기록 및 재생에 관한 것으로서, 특히 오디오신호기록에 있어서 음성신호에 특별한 인코딩작업을 거쳐서 처리된 신호를 기록하고 기록된 신호의 재생시 음성신호를 선택적으로 소거/재성할 수 있는 음성신호 기록/재생시스템에 관한 것으로, 일반적으로 컴팩트 디스크등과 같은 음반이나 테이프등의 기록매체에 오디오신호를 기록하는 경우에 사람의 목소리와 반주음악등을 동시에 녹음을 하므로 사람의 목소리를 필요로 하지 않고 단지 반주음악만을 필요로하는 가라오케용을 제작하기 위해서는 기존의 음반등을 사용할 수 없고 사람의 노랫소리등이 제거된 반주음악만으로 녹음을 하여야하는 별도의 제작과정을 거쳐야만 하는 문제점이 있어 일반 컴팩트 디스크 플레이어난 테이프데크와 같은 오디오기기에서도 제작사에서 가요들을 녹음할때 특변한 인코딩처리를 하여 기존의 오디오 재생기기와의 호환성을 유지하면서 상기 인코딩 처리에 대응하는 특별한 디코딩회로를 가진 재생기기에서는 사람의 노래소리만을 사용자에 의하여 선택적으로 제거시켜서 기존의 오디오 재생기기와 오디오소스만을 가지고도 가라오케의 기능을 가질 수 있도록 할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to recording and reproducing of audio signals. In particular, in audio signal recording, a signal processed through a special encoding operation on a voice signal can be recorded and a voice signal can be selectively erased / reproduced during reproduction of the recorded signal. A voice signal recording / reproducing system. In general, when recording audio signals on a recording medium such as a compact disc or a recording medium such as a tape, a human voice and accompaniment music are simultaneously recorded. In order to produce karaoke dragons that only need accompaniment music, there is a problem that you cannot use existing record lamps and go through a separate production process that requires recording only with accompaniment music from which people's songs are removed. Even in audio equipment like disc players and tape decks, When recording the songs, a special encoding process is performed to maintain compatibility with the existing audio player, while a player having a special decoding circuit corresponding to the encoding process selectively removes only the sound of a human song by a user. Only an audio player and an audio source can be used to have karaoke functions.
