Abstract:
1. A system for processing audio signals, comprising an authoring component configured to: receive a plurality of audio signals; generate an adaptive audio mix comprising a plurality of monophonic audio streams and one or more metadata sets associated with each of the plurality of monophonic audio streams and specifying a playback location of a respective monophonic audio stream, wherein at least some of the plurality of monophonic audio streams are identified as channel-based audio and wherein the others of the plurality of monophonic audio streams are identified as object-based audio, and wherein the playback location of the channel-based audio comprises speaker designations of speakers in a speaker array, and the playback location of the object-based audio comprises a location in three-dimensional space relative to a playback environment containing the speaker array; and further wherein a first metadata set is applied to one or more of the plurality of monophonic audio streams for a first condition of the playback environment, and a second metadata set is applied to the one or more of the plurality of monophonic audio streams for a second condition of the playback environment; and encapsulate the plurality of monophonic audio streams and the at least two metadata sets in a bitstream for transmission to a rendering system configured to render the plurality of monophonic audio streams to a plurality of speaker feeds corresponding to speakers in the playback environment in accordance with the at least two metadata sets based on a condition of the playback environment.
