Abstract
본 발명은 음의 수직이동감을 개선하기 위한 회로에 관한 것으로, 특히 장치의 상하 이동없이 음의 수직이동감을 개선하기 위한 회로에 관한 것으로 디스크등의 기록매체에 기록되어 있는 오디오신호와 수직레벨정보를 재생하여 처리하는 오디오신호 처리장치에 있어서, 외부로부터의 기능키의 입력등에 따라 전체 시스템의 동작을 제어하고 상기 수직레벨정보에 대응하는 위치계수를 포함하여, 음의 수직이동감 개선명령에 따라 입력되는 상기 수직 레벨정보를 디코딩하여 설정되는 가상의 수직상의 음원의 위치에 대응하는 위치계수를 출력하는 마이콤; 입력된 디지탈신호를 돌비프로로직에 따라 신호처리하는 제1디지탈신호처리기(DSP1); 제1디지탈신호처리기에 의하여 처리된 신호를 상기 마이콤으로부터의 위치계수에 따라 디지탈신호처리하는 제2디지탈신호 처리기; 및 제2디지탈신호처리기에 의하여 처리된 디지탈신호를 아날로그신호로 변환하는 디지탈/아날로그 변환기를 포함하여 실제의 음원으로부터 수직위치에 위치하는 가상의 음원으로부터 음을 발생하는 것처럼 처리하여 음의 수직레벨 이동감을 개선시킨다.The present invention relates to a circuit for improving the vertical movement of sound, and more particularly to a circuit for improving the vertical movement of sound without vertical movement of the device. An audio signal processing apparatus for reproducing and processing information, comprising: controlling the operation of the entire system in response to input of a function key from the outside, and including a position coefficient corresponding to the vertical level information, to a negative vertical movement improvement command. A microcomputer outputting a position coefficient corresponding to a position of a virtual vertical sound source set by decoding the vertical level information inputted according to the input; A first digital signal processor (DSP1) for signal-processing the input digital signal according to Dolby Pro Logic; A second digital signal processor for processing a signal processed by the first digital signal processor according to a position coefficient from the microcomputer; And a digital / analog converter for converting the digital signal processed by the second digital signal processor into an analog signal, such that the sound is generated from a virtual sound source located at a vertical position from an actual sound source, thereby moving the sound vertical level. Improve the feeling
