1. A decoder for providing a decoded representation of an audio signal on the basis of an encoded audio stream representing spectral components of frequency bands of the audio signal, the decoder comprising:
a noise filler configured to introduce noise into spectral components of a plurality of frequency bands, to which separate frequency-band specific frequency band gain values are associated, on the basis of a common multi-band noise intensity value,
wherein an individual scaling of noise introduced into different frequency bands is performed on the basis of the separate frequency-band specific frequency band gain values; and
a scale factor gain determinator, which is configured to receive one integer representation of a scale factor per scale factor band and to provide one gain value per scale factor band;
wherein the decoder is configured to receive an encoded version of a noise offset value.
