Abstract

DC60 (27/12/56) An embodiment is described for an adaptive audio system that processes audio data consisting of one or more independent monophonic audio streams. The streams are associated with metadata that identifies whether the streams are channel-based or object-based. The channel-based stream contains playback information encoded using the channel name; and the object-based stream contains location information encoded using a location expression encoded in the associated metadata. The encoder and decoder package the independent audio streams into a single serial stream containing all the audio data. This configuration allows the audio to be played back according to a segmented reference frame in which the playback location is determined by the characteristics of the playback environment (e.g., room size, geometry, etc.) to reflect the mixer's intent. The object location metadata provides an appropriate segmented reference frame of the reference information required to correctly play the audio using the available speaker locations in a room configured to play adaptive audio content. It associates itself with metering data that identifies whether the stream is channel-based or object-based. Channel-based streams contain playback information encoded using the channel name, and object-based streams contain location information encoded using location expressions encoded in the corresponding metering data. The encoder and decoder package the independent audio streams into a single serial stream containing all audio data. This configuration allows the sound to be played back according to a spatialized reference frame, where the playback location is based on the characteristics of the playback environment (e.g., room size, geometry, etc.) to reflect the mixer's intent. The object-position metadata provides the appropriate spatialized reference frame of information required to correctly play the sound using the available speaker positions in a room set up to play adaptive audio content.
