scope:

The present document specifies a coded representation (a bitstream) of audio information, and specifies the decoding process. The coded representation specified herein is suitable for use in digital audio transmission and storage applications.

Building on the technology specified in ETSI TS 103 190-1 [1], the present document specifies additional functionality that can be used for immersive, personalized, or other advanced playback experiences. Additional representations can be included, targeting individual listener groups or applications (providing the possibility of different audio experience settings in addition to those specified in ETSI TS 103 190-1 [1]).

The present document does not specify an object audio renderer, which would be needed to decode object-based audio to a channel-based representation. A reference object audio renderer that may be used with the technology specified in the present document can be found in ETSI TS 103 448 [Error! Reference source not found.].
