Monitoring and Authoring of 3D Immersive Next Generation Audio Formats

The next generation immersive audio formats will require changes in the audio production workflow. Monitoring the audio along with authoring and verifying of dynamic metadata will become a new challenge. — New procedures for managing object based encoded content the same way as for personalization of services through the selection of alternative audio objects (such as commentator languages) needs to be established. — Loudness control during production and the loudness definition for the final output formats are other topics to consider. — The NGA formats will offer a new surround sound experience and the use upmix, format rendering and downmix algorithms will be essential for creating and monitoring the audio programs. — A Multichannel Monitoring & Authoring Unit (MMA) must be compatible with upcoming immersive multichannel 3D audio formats and should offer a platform to host all the emerging immersive 3D audio encoding formats from different vendors.
