Abstract
The spectral domain is efficiently used in order to parameterize the background noise using a background noise estimator configured to determine a parametric background noise estimate based on a spectral decomposition representation of an input audio signal so that the parametric background noise estimate spectrally describes a spectral envelope of a background noise of the input audio signal, thereby yielding a background noise synthesis which is more realistic and thus leads to a more transparent active to inactive phase switching.
