Claim:
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 metadata associated with each of the audio streams and indicating 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 the others of the plurality of monophonic audio streams are identified as object-based audio, and wherein the playback location of a channel-based monophonic audio stream comprises a designation of a speaker in a speaker array, and the playback location of an object-based monophonic audio stream comprises a location in three-dimensional space, and wherein each object-based monophonic audio stream is rendered in at least one specific speaker of the speaker array; and encapsulate the plurality of monophonic audio streams and the metadata 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 a playback environment, wherein the speakers of the speaker array are placed at specific positions within the playback environment, and wherein metadata elements associated with each respective object-based monophonic audio stream indicate whether rendering the respective monophonic audio stream into one or more specific speaker feeds of the plurality of speaker feeds is prohibited, such that the respective object-based monophonic audio stream is not rendered into any of the one or more specific speaker feeds of the plurality of speaker feeds.
