EBU R 128 loudness normalisation recommendation for broadcast audio
New
Description
EBU R 128 is the EBU recommendation for loudness normalisation and permitted maximum audio signal level. The publication defines programme loudness, loudness range and maximum true peak descriptors for broadcast audio workflows. Although widely associated with television, it is also relevant to radio production and distribution when used with radio-specific supplements. It gives engineers and producers a common reference for metering and level management. The EBU page provides the current publication entry and links to the formal document.
