Claim 11:
12. A method for generating encoded audio information comprising one or more encoded audio signals and one or more processed metadata signals, wherein the method comprises:
receiving one or more original metadata signals,
determining the one or more processed metadata signals, and
encoding one or more audio signals to acquire the one or more encoded audio signals,
wherein each of the one or more original metadata signals comprises a plurality of original metadata samples, wherein the original metadata samples of each of the one or more original metadata signals indicate information associated with an audio signal of the one or more audio signals, and
wherein determining the one or more processed metadata signals comprises determining each processed metadata sample of a plurality of processed metadata samples of each processed metadata signal of the one or more processed metadata signals, so that, when a control signal indicates a first state, said processed metadata sample indicates a difference or a quantized difference between one of the plurality of original metadata samples of one of the one or more original metadata signals and of another already generated processed metadata sample of said processed metadata signal, and so that, when the control signal indicates a second state being different from the first state, said processed metadata sample is said one of the original metadata samples of said one of the one or more original metadata signals, or is a quantized representation said one of the original metadata samples.
