Claim 3:
4. The encoder according to claim 1, wherein the gain parameter calculator comprises:
a noise generator configured for generating an encoding noise-like signal;
a synthesizer configured for synthesizing a synthesized signal from the amplified shaped encoding noise-like signal and the prediction coefficients and to provide the synthesized signal;
a comparer configured for comparing the audio signal and the synthesized signal to acquire a measure for a likeness between the audio signal and the synthesized signal; and
a controller configured for determining the gain parameter and to adapt the temporary gain parameter based on the comparison result;
wherein the controller is configured to provide the encoding gain parameter to the bitstream former, when a value of the measure for the likeness is above a threshold value.
