AN AUDIO ENCODER/DECODER APPARATUS

摘要

Apparatus comprising a noise estimator configured to determine a noise estimate for a first part of an audio signal, a comparator configured to compare the noise estimate to an energy threshold parameter, a damping factor determiner configured to determine a damping factor for at least one sub band gain value of a second part of an audio signal, wherein the damping factor is dependent on a result of the comparison and a gain modifier configured to apply the damping factor to the sub band gain value.
