Combining our NGA efforts in an open-source ADM production tool

If you are following our work towards a truly open and codec-independent workflow for Next Generation Audio, you will have noticed that we not only work together with other broadcasters and industry representatives to define relevant standards for that purpose, i.e. Audio Definition Model (ADM), Serial ADM, the ITU ADM Renderer and further specifications. We …

Microchip with description: EAR libear v0.9 d8bc6f2

More open-source for open object-based audio workflows

Last year we released two open-source C++ libraries: libbw64 and libadm. Now that the ITU ADM (Audio Definition Model) Renderer (Recommendation ITU-R BS.2127-0) is published, we are adding another library to the list – the libear. The library is developed in cooperation with BBC R&D and published using the permissive Apache 2.0 license under the …

The EBU ADM Renderer at IBC 2018

One of the key motivations behind our work is the creation and establishment of open, interoperable standards and formats for broadcasters. For Next Generation Audio (NGA) one of the missing puzzle pieces until recently was an open standard for a renderer. With the publication of Tech 3388 (aka the EBU ADM Renderer (EAR)) and the accompanying …

Working on a standardised NGA renderer for the production

A few years ago, we joined the standardization efforts of NGA (Next Generation Audio) components for the production and distribution environment in ITU-R, EBU, DVB and other organizations. Whilst the standardization for the distribution was already almost established, we spent quite some effort on the production format and the production renderer. After many discussions within …

This is possible by representing the audio content as a set of individual assets together with metadata describing their relationships and associations. This allows media objects to be assembled in ground-breaking ways to create new user experiences. Some popular examples …
