Abstract
A method and device are implemented in a multi-channel sound decoder for injecting multi-channel comfort noise in a decoded multi-channel sound signal. Background noise in a decoded mono down-mixed signal is estimated, and comfort noise for each of a plurality of channels of the decoded multi-channel sound signal is calculated in response to the estimated background noise. The calculated comfort noise is injected in the respective channels of the decoded multi-channel sound signal.
