Challenging Changes for Live NGA Immersive Audio Production

Document Thumbnail

The world of broadcast audio is on the verge of a major revolution. Numerous "3D Immersive" formats are developing and will find their way into the mainstream of broadcast production and distribution in the near future. Along with Immersive Audio another category comes into game – Object Based Audio (OBA). All together it describes the Next Generation Audio formats - NGA. What does this mean and what challenge we need to fight with here? OBA will give the end user the option to personalize their experience by selecting personalized audio mixes. In object based audio, an "object" is essentially an audio stream with accompanying descriptive metadata. One of the major challenges for the production side of the industry will be to start OBA production. This means completely rethinking how we perform the final mix because, with OBA, it will be performed at home by the viewer rather than by a mixer in a post-production facility. What does this all mean for the broadcaster? A complete re-build of existing facilities and a total re-think about the audio processing equipment required for outside broadcast vehicles? Well, if we get it right, there will be some changes to overall workflow and hardware. And working with metadata for live streams and in files will become a major challenge. There will be new technical tools and new standards that will help to reach this new level of requirements. Some ideas and facts will be presented.
