Practical Loudness Measurement and Management for Immersive Audio

Loudness management is an essential and often mandatory aspect for content providers and broadcasters. Regional requirements/guidelines based on Recommendation ITU-R BS.1770 form the basis for the loudness practice in broadcasting. It has recently been revised to support new immersive-channel formats, but not explicitly for object-based audio formats. Object-based audio is currently being delivered over-the-top (OTT) and loudness management must be addressed to meet requirements and provide a good user experience. These new audio formats allow the content to be played back over a larger range of playback configurations, which has the potential for loudness variations. This brief describes loudness measurement and management for currently deployed object-based delivery and shows how legacy playback of this content meets the current broadcasting recommendations.
