Abstract
본 발명은 재생시 음향신호와 음성신호를 분리하여 청취하는 것이 가능하도록 하기 위한 오디오신호 기록 및 재생장치에 관한 것이다. 이를 위하여 인가되는 오디오신호를 스테레오모드로 기록하고, 기록된 오디오 신호를 스테레오모드로 재생이 가능한 오디오신호 기록 및 재생장치에 있어서; 기록장치는 ; 제1가산수단; 위상반전수단; 제2가산수단; 과 신호기록수단으로 구성되고; 재생장치는; 제1감산수단; 이득감쇄수단; 음성신호검출수단; 제2감산수단; 제1가산수단; 제2가산수단; 제3가산수단;과 스위칭수단으로 구성된다. 따라서 음향신호와 음성신호를 동시에 또는 음향신호만을 청취할 수 있도록 함으로써 일반적인 오디오신호기록재생장치에 장착하여 폭넓은 이용을 도모할 수 있는 이점이 있다.The present invention relates to an audio signal recording and reproducing apparatus for making it possible to separately listen to an audio signal and an audio signal during reproduction. An audio signal recording and reproducing apparatus capable of recording an applied audio signal in a stereo mode and reproducing the recorded audio signal in a stereo mode for this purpose; Recording device; First adding means; Phase inverting means; Second adding means; And signal recording means; The playback device; First subtracting means; Gain reduction means; Voice signal detection means; Second subtracting means; First adding means; Second adding means; A third adding means and a switching means. Therefore, by allowing the audio signal and the audio signal to be listened to at the same time or only the audio signal, there is an advantage in that it can be widely used in a general audio signal recording and reproducing apparatus.
