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: a. the available resources of the device to achieve appropriate SPL, b. environmental or physical conditions that affect the way a given loudness level and dynamic range are experienced, c. user preferences that change the required loudness and dynamic range. NOTE: This standard is intended to be used along with implementation information provided by codec suppliers.
