Abstract
A method for generation of comfort noise for at least two audio channels. The method comprises determining a spatial coherence between audio signals on the respective audio channels, wherein at least one spatial coherence value per frame and frequency band is determined to form a vector of spatial coherence values. A vector of predicted spatial coherence values is formed by a weighted combination of a first coherence prediction and a second coherence prediction that are combined using a weight factor a. The method comprises signaling information about the weight factor a to the receiving node, for enabling the generation of the comfort noise for the at least two audio channels at the receiving node.
