Loudness Standard for Over the Top Television and Online Video Distribution for Mobile and Fixed Devices (ANSI/CTA-2075)
This standard applies to devices, whether mobile or fixed, that receive OTT and OVD services and create audio output either through a built-in loudspeaker or through an interface to an external transducer or another A/V device. It describes the management of loudness and dynamic range within a device, with or without the use of metadata, to optimize the listener experience considering:
the available resources of the device to achieve appropriate SPL,
environmental or physical conditions that affect the way a given loudness level and dynamic range are experienced,
user preferences that change the required loudness and dynamic range.
