EBU Technology & Innovation Workplan
Every two years, the EBU develops a roadmap for technology and innovation activities based on the requirements and inputs given by EBU Members. The result of this roadmap is our bi-annual EBU Technology & Innovation Workplan. Strategic programmes and project groups are set up to focus on specific areas of interest. To access the latest Workplan, click here.
EBU Strategic Programme on Audio Systems
- Helps Members to maximise the quality and availability of sound production technology.
- Provides guidance and working documents to help you make the move to new audio systems: audio production and broadcasting are being transformed by new technologies. The next generation of audio experiences will be more immersive than ever before and interactive. It is important that broadcasters look at new file formats to deliver and produce audio in these advanced systems.
- We take into consideration your feedback when making contributions to ITU and ETSI standards and organize seminars and trainings to enable you to use new technologies and share best practice.
If you are interested in Audio Systems, join our group on this topic and participate in the discussions. Some restrictions may apply.
The EBU Strategic Programme on Audio Systems (formerly FAR) provides guidance to help broadcasters make the move to new (IP-based) audio systems, provides input to ITU and ETSI standardization, and organize seminars and workshops to enable sharing of best practices in new audio production technology.
Audio systems target the development of the missing ecosystem that links content creators with the sound rendering function in end-users devices.
These objectives are driven by the object-based audio (OBA) approach developed in the Audio Definition Model (ADM) of EBUCore.
The PLOUD group falls within Audio Systems' remit and it will continue with work on audio loudness.
EBU Audio Systems consists of two parts:
- AS-EBU, which is restricted to EBU Members (public service media organizations)
- AS-ALL, which includes the EBU members and all industry professionals (including equipment manufacturers, research organizations, etc.)
When you join EBU Audio Systems, you are automatically added to the appropriate e-mail reflector(s) and given access to the relevant workspaces and other tools.
How we work
The actual work is performed via the e-mail reflector(s) and webexes to coordinate the work and keep all in-sync regarding the latest activitities.
The best place to start for an overview of what is going on is AS workspace.
If you have any questions/need help, please contact the coordinator: Roger Miles (EBU).

The Audio Description metadata Model provides a formalised description of audio content for many types of audio file (e.g. BWF, BW64).
The 64-bit audio file format meets the requirements for NGA and multichannel sound in broadcasting and audio archiving. As with the 16-bit BWF it is based on the Microsoft RIFF/WAVE format.
This Technical Report provides a concrete and practical example of an object-based audio architecture and workflow, from production to broadcast and broadband delivery.

The December 2016 issue of tech-i looks at Next Generation Audio, the promise of 5G networks, the new .radio TLD and much more.
The document presents practical guidelines to relevant settings and processing in the signal chain from the studio to consumer equipment. It aims to achieve consistent loudness levels throughout the complete chain from broadcaster to consumer. This is version 2.1, July 2016; editorial changes only (pagination, typos and fonts).
In the latest EBU Technical Review, Rozenn Nicol, Marc Emerit, Edwige Roncière, Hervé Déjardin from nouvOson, discuss the progress of the nouvOson player project since 2013 and its future outlook.
Recommendation concerning permissible tolerances of video signals in digital television systems.
This supplement to EBU R 128 specifies a special set of loudness parameters for short-form content. This version 2.0 puts emphasis on the permitted Maximum Short-term loudness and does no longer include the use of the Max. Momentary Loudness limit.
In this document the properties of a loudness meter in the so-called ‘EBU Mode’ are introduced and explained in detail. This version 3.0 includes new minimum requirement test signals, clarifications and a new requirement on LRA stability signalling. This set of test signals complements the document.
The ‘Loudness Range’ (LRA) measure and the algorithm for its computation is introduced and explained in detail. Loudness Range is supplementary to the main audio Programme Loudness described in EBU R 128. This is version 3.0.
The document describes how to change audio levelling from peak normalisation to loudness normalisation in accordance with EBU R 128. This version 3.0 is a completely updated version based on 5 years of experiences in the use of loudness normalization.
Recommendation to use an average programme loudness of -23 LUFS and the 'Loudness Range' and 'Maximum True Peak Level' descriptors. Version 3.0 (June 2014).
EBU Recommendation 128 is a milestone in the history of audio broadcasting. It started a loudness revolution by specifying normalized loudness levels in production, in play-out systems and, potentially, in many other applications. This article explains how distributors could support the good broadcasters while improving consumer satisfaction at the same time.
This article describes the success of the implemention of loudness normalization on DAB broadcasts in Norway with a few words on other radio platforms. Thus far, loudness awareness has been almost exclusive to television. Could loudness normalization also be employed in radio? And if yes, what radio platforms could benefit from it? Find out by reading this article.
The March 2012 issue of tech-i covers TV White Spaces, LED lights, colorimetry and storage. You'll also find three radio-related articles, from FM swtich-off plans in Norway, to Loudness considerations and a strategic view from Lieven Vermaele. Finally, RTR's Igor Orlov is "in the spotlight" and David Wood asks how much R&D should be done by broadcasters.
The EBU R 128 logo is the symbol of the EBU Recommendation R 128 on Loudness normalisation and permitted maximum level of audio signals. Use of the logo by third parties is allowed subject to the rules in this document.
This is version 2 of the Broadcast Wave Format (BWF) specification. This is a substantial revision that incorporates Loudness Metadata (in accordance with EBU R 128) and which takes account of the publication of Supplements 1 – 6 and other relevant documentation.
This article describes one of the most fundamental changes in the history of audio in broadcasting: the change of the levelling paradigm from peak normalisation to loudness normalisation.
This is the third issue of tech-i, the EBU TECHNICAL department quarterly magazine which include the following articles such as: the New EBU Technical structure, loudness awareness, eco displays, tapeless environments, CES report, HIPs, seminar news & diary.
A loudness war is taking place from CD mastering to broadcasting. The purpose of this article is to justify and recommend more fitting ways of measuring and controlling the audio level in digital broadcasting than looking at isolated samples or quasi-peak levels.
This article on Loudness control – while representing the views of the author – is based on a discussion paper submitted to the 5th Meeting of EBU Project Group P/AGA (Advisory Group on Audio), held at BBC R&D in December 2003.
This article presents some solutions for avoiding loudness differences in radio and television broadcasting, based on levelling recommendations and a newly-developed loudness algorithm.
In this short article, the author describes some of the difficulties encountered with setting audio levels and loudness in the new digital environment.
Dolby Dialogue Normalization and Dynamic Range Control – are described here with particular reference to digital TV.
In DAB a dynamic range control (DRC) signal mayb be used to effect unobtrusive compression of the programme dynamics, if required. A music/speech control (MSC) signal, which is also transmitted, will enable the listener to balance the loudness of different types of programme according to taste.
