最近，引入了新一代的空间音频格式，其包括高架扬声器并且在空间真实性方面超过了传统的环绕声格式，诸如5.1。为了促进3D声音的高质量比特率高效分布和灵活再现，MPEG标准化组最近开始了MPEG-H音频编码开发，用于从基于声道、基于对象和基于HOA的输入中通用地传送编码的3D声音。高质量的再现支持许多输出格式，从22.2及以上到5.1，立体声和双耳再现独立于原始编码格式，从而克服了各种3D格式之间的不兼容性。本文介绍了标准化项目的现状，并概述了系统架构、功能和性能。
Recently, a new generation of spatial audio formats were introduced that include elevated loudspeakers and surpass traditional surround sound formats, such as 5.1, in terms of spatial realism. To facilitate high-quality bitrate-efficient distribution and flexible reproduction of 3D sound, the MPEG standardization group recently started the MPEG-H Audio Coding development for the universal carriage of encoded 3D sound from channel-based, object-based and HOA-based input. High quality reproduction is supported for many output formats from 22.2 and beyond down to 5.1, stereo and binaural reproduction independently of the original encoding format, thus overcoming incompatibility between various 3D formats. The paper describes the current status of the standardization project and provides an overview of the system architecture, its capabilities and performance.
