Claim Text:
1. A method of encoding an audio soundtrack, comprising the steps of: receiving a base mix signal representing a physical sound; receiving at least one object audio signal, each object audio signal having at least one audio object component of the audio soundtrack; receiving at least one object mix cue stream, the object mix cue streams defining mixing parameters of the object audio signals; receiving at least one object render cue stream, the object render cue streams defining rendering parameters for rendering the object audio signals in a target spatial audio format; encoding the object audio signals by a first audio encoding processor to obtain encoded object audio signals that contain encoded audio objects; decoding the encoded object audio signals by a first audio decoding processor; utilizing the decoded object audio signals and the object mix cue streams to combine the audio object components with the base mix signal, thereby obtaining a downmix signal; and multiplexing the downmix signal, the encoded object audio signals, the object render cue streams, and the object mix cue streams to form a soundtrack data stream.
