MPEG-H Audio is a Next Generation Audio (NGA) system offering a new audio experience for the audience in various applications: Object-based immersive sound delivers a new degree of realism and artistic freedom for immersive music applications, such as the 360 Reality Audio music service. Advanced interactivity options enable improved personalization and accessibility, including solutions to create object-based features out of legacy material, e.g. deep-learning-based dialogue enhancement. 'Universal delivery' allows for optimal rendering of one production over all kinds of devices and various distribution ways, e.g. broadcast or streaming. All of these new features are achieved by adding metadata to the audio, which is defined during production and offers content providers flexible control of interaction and rendering options. Thus, new possibilities and requirements during the production process are imposed. In this paper, examples of state-of-the-art NGA production workflows are detailed and discussed, with special focus on immersive music, broadcast, and accessibility.
