Claim 2:
3. The encoder according to claim 1, wherein the gain parameter calculator comprises:
a noise generator configured for generating an encoding noise-like signal;
a comparer configured for comparing the unvoiced residual signal and the amplified shaped encoding noise-like signal to acquire a measure for a likeness between the unvoiced residual signal and the amplified shaped encoding noise-like 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.
