Abstract

본 발명은 음성다중 신호처리장치에 관한 것으로, 종래에는 채널 전환시나 모드 전환시에 팝 노이즈가 발생하여 거슬리는 음질의 오디오를 청취해야 하는 문제점이 있었다. 따라서, 본 고안은 그 채널 전환시나 모드 전환시에 발생하는 팝 노이즈를 제거하여 음질이 깨끗한 방송을 청취할 수 있도록 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiplex audio signal processing apparatus. In the related art, pop noise is generated during channel switching or mode switching. Therefore, the present invention eliminates pop noise generated at the time of channel switching or mode switching, allowing the user to listen to broadcasts with clear sound quality.
