Abstract

이 발명은 자동 음색 조정방법 및 장치에 관한 것으로서, 입력된 음악의 패턴을 데이타 메모리에 저장하고, 여러 종류의 음악 패턴이 저장된 기준 패턴 롬 테이블의 기준 패턴과 비교하여, 상기 입력된 음악의 패턴이 상기 기준 패턴 롬 테이블에 저장된 음악패턴에 가장 가까운 패턴을 찾아 그 패턴에 할당된 계수를 계수 롬 테이블에서 검출하여 디지탈 이퀼라이저에 인가함으로써 디지탈 이퀼라이저가 자동으로 이퀼라이징되도록 구성되어 있다. 따라서, 사용자가 입력되는 음악에 따라 번번히 이퀼라이저를 조작하지 않아도 되는 이점이 있다. 이 발명은 모든 오디오 기기에 적용하여 사용할 수 있다.The present invention relates to a method and apparatus for automatic tone adjustment, wherein the input music pattern is stored in a data memory, and the input music pattern is compared with a reference pattern in a reference pattern ROM table in which various types of music patterns are stored. The digital equalizer is automatically equalized by finding a pattern closest to the music pattern stored in the reference pattern ROM table, detecting a coefficient assigned to the pattern in the coefficient ROM table, and applying the same to the digital equalizer. Therefore, there is an advantage that the user does not have to operate the equalizer in accordance with the input music. This invention can be applied to all audio devices.
