We are very proud to inform you about the first public release of the “EAR Production Suite”, a free set of tools for producing immersive and personalizable audio content independently from the distribution codec. This open-source project has been developed in (yet) another great collaboration with our colleagues from the BBC R&D audio team under …
In the Immersive Accessibility (ImAc) project IRT investigates, together with partners from the media industry, how 360° media can be made accessible for all. During the project, a technical platform has been developed to enable accessible 360° media: enrich, distribute and playback 360° video content with fully customisable accessibility services. To this end, the project …
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 …
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 …
In previous posts we informed about the progress and achievements related to our Next Generation Audio renderer work, especially about the EBU ADM Renderer or simply the “EAR”. At the last ITU-R WP6C meeting in Geneva, where international standards for production and quality topics in broadcasting are discussed and made, we finally achieved one of …
If you are a regular visitor of the IRT Lab, you already know the EBU ADM Renderer (EAR) – a renderer for Next Generation Audio content described by ADM metadata. The specification is published as EBU Tech 3388 and it is accompanied by an open source reference implementation written in the programming language Python. Now …
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 …
Together with multiple other EBU members we developed the EBU ADM Renderer (EAR), a production renderer for audio described by ADM metadata. It is specified in EBU Tech 3388 and accompanied by an open-source reference implementation written in Python. Recently all the hard work we put into this project got rewarded: the EAR won the …
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 …
IRT recently released version 1.0 of it’s Subtitle Conversion Framework (SCF). The SCF is published under the Apache 2.0 license and is available on github: https://github.com/IRT-Open-Source/scf The SCF provides a set of modules for converting XML based subtitle formats. The modules include features for Transformation from EBU STL to EBU-TT according to the mapping guideline …
