Abstract

본 발명은 중앙처리부(2)의 제어를 받아 실시간 음정변환을 할 수 있는 하나 이상의 음정변환회로(3)를 두어, 데이터메모리(7) 또는 음반에 수록되어 있는 음정변환회로(3)를 제어하기 위한 데이터에 따라 중앙처리부(2)에서 각각의 음정변환회로(3)를 제어하여 각각의 음정변환회로(3)에 동시에 입력되는 하나의 입력신호를 실시간 음정변환하여 저주파증폭부(5)에서 입력신호와 함께 동시에 출력함으로써 다중화음으로 만드는 방법 및 이를 적용한 기기에 관한 것이다.The present invention has one or more pitch conversion circuits (3) capable of real-time pitch conversion under the control of the central processing unit (2) to control the pitch conversion circuit (3) contained in the data memory (7) or record. The central processing unit 2 controls each pitch conversion circuit 3 according to the data for real-time pitch conversion of one input signal simultaneously input to each pitch conversion circuit 3 and inputs it from the low frequency amplifier 5. The present invention relates to a method of making a multiplexed sound by simultaneously outputting a signal and a device to which the same is applied.

본 발명은 특히 단순한 음이 아닌 언어를 사용하는 음성에 적용할 수 있는 것으로서, 무인반주기에 적용할 경우 다중화음의 멜로디로 편곡되어진 노래를 한 사람이 한 멜로디만을 노래부르는 것으로도 여러사람이 각각 동시에 다중화음의 멜로디로 노래부르는 것과 같은 효과를 얻을 수 있으며, 기타 무인반주기뿐만 아니라 다른 여러가지 용도에 적용될 수 있다.The present invention is particularly applicable to a voice using a language other than a simple sound, and when applied to an unmanned half-cycle, a single person sings only one melody in a song arranged as a multi-melody melody. You can achieve the same effect as singing with melodies of multiple chords, and can be applied not only to other drone cycles but also to many other uses.

Claims

One or more pitch conversion circuits (3) capable of real-time pitch conversion under control of the central processing unit (2) are provided so that the data for controlling the pitch conversion circuit (3) stored in the data memory (7) or record. Accordingly, the central processing unit 2 controls each pitch conversion circuit 3 so as to perform real-time pitch conversion of one input signal input to each pitch conversion circuit 3 together with the input signal in the low frequency amplifier 5. How to make multiple sounds by outputting at the same time.
