Convention Paper

The Audio Definition Model—A Flexible Standardized Representation for Next Generation Audio Content in Broadcasting and Beyond

Authors: Füg, Simone; Marston, David; Norcross, Scott

AES Convention 141 · Paper 9626 · September 2016

Abstract

Audio for broadcasting around the world is evolving towards new immersive and personalized audio formats, which require accompanying metadata along with the audio essence. This paper introduces the Audio Definition Model (ADM), as specified in Recommendation ITU-R BS.2076 (and EBU Tech 3364), which is an XML-based generalized metadata model that can be used to define the required metadata. The ADM is able to describe channel-based, object-based, and scene-based audio in a formalized way. The ADM can be incorporated into RIFF/WAV-based files, such as BW64 (Recommendation ITU-R BS.2088), and can therefore be deployed in RIFF/WAV-based applications, handling immersive content, while maintaining compatibility to legacy content. This allows for program production and exchange of audio programs in these new audio formats.
