Claim 5:
6. A method for rendering audio signals, comprising:
receiving a bitstream comprising encoded audio data representing a plurality of monophonic audio streams, and further comprising 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 object-based audio, and wherein the playback location of an object-based monophonic audio stream comprises a location in three-dimensional space, wherein at least some other of the plurality of monophonic audio streams are identified as channel-based audio, and wherein the playback location of a channel-based monophonic audio stream comprises a designation of a speaker in a speaker array;
decoding the encoded audio data to provide the plurality of monophonic audio bitstreams; and
rendering the plurality of monophonic audio streams to a plurality of speaker feeds corresponding to speakers in a playback environment, wherein the speakers are placed at specific positions within the playback environment, and wherein one or more additional 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.
