Abstract

Next Generation Audio (NGA) systems like MPEG-H Audio rely on metadata to enable a wide variety of features. Information such as channel layouts, the position and properties of audio objects, and user interactivity options are only some of the data that can be used to improve consumer experience. Creating these metadata requires suitable tools, which are used in a process known as "authoring", where interactive features and the options for 3D immersive sound rendering are defined by the content creator. Different types of productions impose specific requirements on these authoring tools, which leads to a number of solutions appearing in the market. Using the example of MPEG-H Audio, this paper will detail some of the latest developments and authoring solutions designed to enable immersive and interactive live and post-productions.
