Abstract:
An audio decoder configured to produce an audio signal from a bitstream containing audio frames includes: a core band decoding module configured to derive a directly decoded core band audio signal from the bitstream; a bandwidth extension module configured to derive a parametrically decoded bandwidth extension audio signal from the core band audio signal and from the bitstream, wherein the bandwidth extension audio signal is based on a frequency domain signal having at least one frequency band; and a combiner configured to combine the core band audio signal and the bandwidth extension audio signal so as to produce the audio signal; wherein the bandwidth extension module includes an energy adjusting module being configured in such way that in a current audio frame in which an audio frame loss occurs, an adjusted signal energy for the current audio frame for the at least one frequency band is set.

Claim (Index 7):
Audio decoder according to  claim 5 , wherein the gain factor lowering procedure comprises the step of lowering the current gain factor by dividing the current gain factor by a second figure which is large than the first figure in case the current gain factor exceeds a second threshold which is larger than the first threshold.
