Abstract
A method for generating comfort noise is provided. The method includes providing a first set of background noise parameters Nfor at least one audio signal in a first spatial audio coding mode and a second set of background noise parameters Nfor the at least one audio signal in a second spatial audio coding mode. The first spatial audio coding mode is used for active segments; the second spatial audio coding mode is used for inactive segments. The method further includes adapting the first set of background noise parameters Nto the second spatial audio coding mode, thereby providing a first set of adapted background noise parameters {circumflex over (N)}. The method further includes generating comfort noise parameters by combining {circumflex over (N)}and Nover a transition period. The method further includes generating comfort noise based on the comfort noise parameters.
