Abstract

Object-based audio coding technology has been interested with its expectation to apply in wide areas. Recently, ISO/IEC MPEG has standardized a parametric object audio coding method, the SAOC (Spatial Audio Object Coding). This paper introduces parametric object audio coding techniques with special focus on the MPEG SAOC and also describes several issues and solutions that should be considered for a success in its application.

객체 기반 오디오 부호화 기술은 다양한 응용 분야를 기대할 수 있는 차세대 오디오 기술로써 관심이 높다. 최근 MPEG에서는 SAOC (Spatial Audio Object Coding)라는 압축 효율이 우수한 Parametric 객체 부호화 방법을 표준화하였다. 본 논문에서는 SAOC를 중심으로 Parametric 객체 오디오 부호화의 기술을 소개하고, 이를 실제 적용하기 위한 고려사항들에 대해 다룬다.
