Abstract:
The invention provides a decoder being configured for processing an encoded audio bitstream, wherein the decoder includes: a bitstream decoder configured to derive a decoded audio signal from the bitstream, wherein the decoded audio signal includes at least one decoded frame; a noise estimation device configured to produce a noise estimation signal containing an estimation of the level and/or the spectral shape of a noise in the decoded audio signal; a comfort noise generating device configured to derive a comfort noise signal from the noise estimation signal; and a combiner configured to combine the decoded frame of the decoded audio signal and the comfort noise signal in order to obtain an audio output signal.

Claim (Index 10):
A decoder according to  claim 7 , wherein the control device comprises a wanted signal energy estimator configured to determine an energy of a wanted signal of the decoded audio signal, a noise energy estimator configured to determine an energy of a noise of the decoded audio signal and a signal-to-noise ratio estimator configured to determine the signal-to-noise ratio of the decoded audio signal based on the energy of wanted signal and based on the energy of the noise, wherein the switch device is switched depending on the signal-to-noise ratio determined by the control device.
