FIELD: data processing.
SUBSTANCE: invention relates to audio encoding and decoding. Apparatus for generating one or more audio channels comprises: a metadata decoder for generating one or more reconstructed metadata signals from one or more processed metadata signals depending on a control signal, wherein each of the one or more reconstructed metadata signals indicates information associated with an audio object signal of one or more audio object signals, wherein the metadata decoder is configured to generate the one or more reconstructed metadata signals by determining a plurality of reconstructed metadata samples for each of the one or more reconstructed metadata signals; and 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.
EFFECT: ensuring efficient encoding/decoding of object metadata.
