Abstract

본 발명은 음장효과의 제어에 관한 것으로, 테이프 포맷상의 적절한 부분 (DAT에서는 팩 데이타 영역)을 정하여 키 조작을 통해 음장효과 제어 데이타를 테 이프에 기록하고 재생시에 그 데이타를 이용하여 음장효과를 내도록 함으로써 정해진 음악을 들을 때마다 음장효과 장치를 조정하는 불편함을 제거해준다.The present invention relates to the control of sound field effects, and to define an appropriate portion on a tape format (pack data area in DAT) to record sound field effect control data on a tape through key manipulation and to use the data at the time of playback to produce a sound field effect. This eliminates the inconvenience of adjusting the sound field effect device every time you listen to a given piece of music.

Claims

A deck unit 1 for actually recording the recorded data on the tape according to the control signal from the digital signal processing unit and reproducing and outputting the data recorded on the tape under external control, and the data input at the time of recording the sound field effect control signal. A digital signal processor 5 for outputting to the deck unit 1 for recording, and an A / D converter for converting an analog signal into a digital signal upon reproduction of data recorded on a tape and inputting the digital signal to the digital signal processor 5. (4) and store the data of the selected sound field effect in the internal register when the deck unit 1 is in recording standby, and store the sound field effect control data stored in the register when the deck unit 1 is in recording mode. A system control section (2) for controlling the digital signal processing section (5) to record on a tape, and whether or not recording of a sound field effect control signal is applied to the system and selecting a sound field effect Is a key input section 3, a sound field effect processing section 6 for imparting a sound field effect to the reproduced audio signal according to the input sound field effect control data, and a digital signal output from the sound field effect processing section 6 as an analog signal. And a signal amplifier (8) for amplifying the analog signal output from the D / A converter (7) and outputting the speaker through the speaker (9). Sound field effect control circuit.
