Abstract
An example device for receiving audio data includes an audio decoder implemented using digital logic circuitry and configured to decode audio data conforming to MPEG-H or AC-4 part 2, and an audio data processing unit implemented in digital logic circuitry and configured to receive a manifest file describing a plurality of audio objects conforming to MPEG-H or AC-4 part 2, wherein the manifest file indicates whether each of the audio objects is available via broadcast, broadband, or both broadcast and broadband, receive selection data indicating which of the audio objects are to be presented, receive streamed media data including the audio objects based on the selection data, and provide the audio objects indicated by the selection data to the audio decoder.
