Abstract:
An apparatus for generating one or more audio channels is provided. The apparatus includes a metadata decoder for receiving one or more compressed metadata signals. Each of the one or more compressed metadata signals includes a plurality of first metadata samples. The metadata decoder is configured to generate one or more reconstructed metadata signals and to generate each of the second metadata samples of each reconstructed metadata signal of the one or more reconstructed metadata signals depending on at least two of the first metadata samples of the reconstructed metadata signal. The apparatus includes an audio channel generator for generating the one or more audio channels depending on the one or more audio object signals and depending on the one or more reconstructed metadata signals. An apparatus for generating encoded audio information including one or more encoded audio signals and one or more compressed metadata signals is provided.
