Remarks

The AudioPresentation class encapsulates the information that describes an audio presentation which is available in next generation audio content.

Used by MediaExtractorMediaExtractor#getAudioPresentations(int) and AudioTrackAudioTrack#setPresentation(AudioPresentation) to query available presentations and to select one, respectively.

A list of available audio presentations in a media source can be queried using MediaExtractor#getAudioPresentations(int). This list can be presented to a user for selection. An AudioPresentation can be passed to an offloaded audio decoder via AudioTrack#setPresentation(AudioPresentation) to request decoding of the selected presentation. An audio stream may contain multiple presentations that differ by language, accessibility, end point mastering and dialogue enhancement. An audio presentation may also have a set of description labels in different languages to help the user to make an informed selection.

Applications that parse media streams and extract presentation information on their own can create instances of AudioPresentation by using AudioPresentation.Builder class.
