Audio Systems and workflows

Helps Members to maximise the quality and availability of sound production technology.

The next generation of audio experiences will be more immersive, personal and accessible than ever before. It is important that broadcasters look at new file formats to deliver and produce audio in these advanced systems.


Currently the following deliverables are planned (green indicates the deliverable has already been delivered). Note that deliverables are dependent on enough participation in the work and that the planning is subject to change. New deliverables are added regularly.

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 for these advanced systems.

The Audio Systems group aims to:

  • Help EBU Members to maximise the quality and availability of sound production technology;
  • Provide guidance and working documents to help make the move to new Audio Systems;
  • Take into consideration professional users' feedback when making contributions to ITU and ETSI standards;
  • Organize seminars and trainings to enable the use of new technologies and to share best practice.

The EBU Audio Systems group (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.

Two parts

EBU Audio Systems consists of two parts:

  1. AS which is restricted to EBU Members (public service media organizations)
  2. 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: Paola Sunna (EBU)
