Standard: MPEG-D
Part: 4

This document specifies technology for loudness and dynamic range control (DRC). It is applicable to most MPEG audio technologies. It offers flexible solutions to efficiently support the widespread demand for technologies such as loudness normalization and dynamic range compression for various playback scenarios. It addresses a wide range of content delivery use cases including media streaming and broadcast applications. The associated metadata is attached to the audio content and can be applied during playback to enhance the user experience in scenarios such as ‘in the car’ or ‘late at night’. The integrated loudness control can be used, for instance, to meet regulatory requirements. An advanced peak and clipping control are fully integrated.
