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 similar to the 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 next-generation audio (NGA) formats will offer a new surround sound experience, and the use of upmix, format rendering, and downmix algorithms will be essential for creating and monitoring audio programs. A multichannel monitoring and authoring unit (MMA) must be compatible with upcoming immersive multichannel three-dimensional (3D) audio formats and should offer a platform to host all the emerging immersive 3D audio-encoding formats from different vendors.
