摘　　要：本文是对《中央人民广播电台2016年度战略资源推介会》全景声开场声音秀节目《声华》的混音与重放系统进行探索性设计的记录。由于场地重放条件的限制,不能使用标准全景声的制作和编码软件,使节目成为某种固定格式的编码文件,比如"杜比全景声"(Dolby Atmos)等文件。而且,《声华》所要求的重放声场要超过杜比全景声(Dolby Atmos)所包含的更多的维度来呈现其内容细节。所以整个节目的混音和重放平台必须具有最大的灵活性和适应性,这一切不仅要从零开始,还要有突破和创新。通过最终现场重放活动的实际检验证明,《声华》的非编码全景声系统的搭建与创新性设计是成功的。This article is a record of the explorational design of the sound mixing and replay system of a TV program ＂ShengHua＂ full-round sound field opening sound show of CNR 2016 Strategic Resource Introduction and Marketing Event.Adoption of production and encoding software for standard full-round sound field can make the program to be a fixed encoding document format,such as Dolby Atmos.Due to the restrictions on the replay system,the kind of form cannot be used.Furthermore, ＂ShengHua＂ requires a replay system that can contain more dimensions to show its details than Dolby Atmos.Therefore,the sound mixing and replay platform must have the maximum flexibility and adaptability,not only starting from scratch and also showing some innovations.The final test of the onsite replay already proves it is a success to build and design ＂ShengHua＂ non-encoding full-round sound field system.
