Abstract
An encoder provides an audio stream based on a transform-domain representation of an input audio signal and includes a quantization error calculator configured to determine a multi-band quantization error over a plurality of frequency bands of the input audio signal for which separate band gain information is available. The encoder also includes an audio stream provider for providing the audio stream such that the audio stream includes information describing an audio content of the frequency bands and information describing the multi-band quantization error. A decoder provides a decoded representation of an audio signal based on an encoded audio stream representing spectral components of frequency bands of the audio signal and includes a noise filler for introducing noise into spectral components of a plurality of frequency bands to which separate frequency band gain information is associated on the basis of a common multi-band noise intensity value.
