Audio Systems

Scope

The Audio Systems group helps Members make the best use of sound production technology across three main areas: personalised sound experiences, radio production, and loudness. For each area, the group maintains dedicated working spaces and mailing lists. Our work spans the full range of audio production challenges facing public service media — from the technical standards that underpin audio exchange and delivery, to the practical workflows that broadcasters use every day. We also coordinate the ADM Implementers Group, which is open to Members, industry, and other interested parties.

Subgroups

ADM IG

We develop strategies and tools for broad implementation of ADM and S-ADM, enabling interoperable immersive and personalised audio workflows.

Loudness

We maintain and extend EBU R 128, the broadcast loudness normalisation standard, covering NGA, radio, and cinematic content applications.

Personalised Sound Experiences

We advance personalised and immersive audio for PSM, working on NGA codecs, ADM metadata, and interoperability across production and delivery.

Objectives

We advance audio production capabilities for EBU Members by developing guidance, profiles, and tools across our three focus areas. We maintain and develop the EBU R 128 loudness recommendation, work on next-generation audio personalisation using ADM and S-ADM, and provide a forum for radio production workflow exchange. We engage with standards bodies including ITU-R, SMPTE, and the EBU Technical Committee to ensure PSM requirements are reflected in the standards that govern audio production and distribution.
