FIELD: data processing.
SUBSTANCE: invention relates to means for forming one or more audio channels. One or more compressed metadata signals are received. Each of the compressed metadata signals comprises a plurality of first metadata samples. First metadata samples of each of the compressed metadata signals indicate the information associated with the audio object signal for one or more audio object signals. One or more recovered metadata signals are generated such that each reconstructed metadata signal contains the first metadata samples of the compressed metadata signal, wherein said recovered metadata signal is associated with said compressed metadata signal and further comprises a plurality of second metadata samples. Generating recovered metadata signals comprises the step where second metadata samples of each of the reconstructed metadata signals are generated by generating a plurality of approximated metadata samples for said recovered metadata signal.
EFFECT: increase in the efficiency of metadata coding.
