본 논문에서는 입체음향효과의 향상을 위한 스테레오-10.2채널의 블라인드 업믹스 알고리즘을 제안하였다. 최근에, 소비자들은 더 나은 입체음향효과나 3D 사운드를 즐기길 원하고 다양한 멀티채널 포맷의 등장으로 업믹스 알고리즘들이 연구 되어 왔다. 그러나 기존의 업믹스 알고리즘들은 공간정보를 왜곡하는 문제점을 가지고 있었다. 이러한 문제점을 해결하기위해 전 후방 채널에 대한 이득 조절 및 10.2 채널의 각 채널별 믹싱 알고리즘을 제안한다. 기존의 상용화된 멀티채널 업믹스 알고리즘들과의 주관적 평가 실험결과 제안한 알고리즘은 입력신호의 공간정보를 유지하면서 입체음향효과를 향상시킨 것으로 확인되었다.
