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 …
After the switch of the TV format from 4:3 to 16:9, other aspect ratios remained at best a niche product for a long time in the broadcasting industry. But social media are defining entirely new standards on their platforms. This challenges video producers to provide their content to various distribution channels – including the need …
In the course of the AES “Virtual Vienna” Convention 2020, the Binaural NGA Renderer, our binaural rendering addon for the EBU ADM Renderer, was released together with a corresponding paper. The Binaural NGA Renderer was released as an open source project and can be found at https://github.com/IRT-Open-Source/binaural_nga_renderer. The corresponding paper with the title “Optimized binaural rendering …
Audio is on the brink of the next big step after the transition from mono to stereo. Next Generation Audio (NGA) and especially object-based audio will provide the consumer with a lot of new features such as personalizable dialogue level. Check out this EBU website for an introduction into NGA and an overview of the …
Since the first release of the EBU ADM Renderer, the implementation of 3D audio via headphones through binaural technology has been a desired functionality. Binaural technology provides the ability to easily deliver three-dimensional, immersive content to the listener. All the listener needs for this is headphones. This makes it possible to listen to spatially demanding …
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 …
Our efforts to establish a Next Generation Audio (NGA) production workflow based on open standards is still ongoing. Next Generation Audio is designed to deliver highly adaptable audio for immersive, more personalized experiences and accessibility services. The Audio Definition Model (ADM) and the EBU ADM Renderer (EAR) are the backbone of the production workflow we …
