Abstract:
An encoder for encoding an audio signal has: an analyzer configured for deriving prediction coefficients and a residual signal from an unvoiced frame of the audio signal; a gain parameter calculator configured for calculating a first gain parameter information for defining a first excitation signal related to a deterministic codebook and for calculating a second gain parameter information for defining a second excitation signal related to a noise-like signal for the unvoiced frame; and a bitstream former configured for forming an output signal based on an information related to a voiced signal frame, the first gain parameter information and the second gain parameter information.

Claim (Index 9):
The encoder according to  claim 1 , further comprising a quantizer configured for quantizing the first gain parameter to acquire a quantized first gain parameter, wherein the gain parameter controller is configured for determining the first gain parameter as a based on: g c = \u2211 n = 0 Lsf - 1 \ue89e \ue89e xw \ue8a0 ( n ) \u00b7 cw \ue8a0 ( n ) \u2211 n = 0 Lsf - 1 \ue89e \ue89e cw \ue8a0 ( n ) \u00b7 cw \ue8a0 ( n ) wherein gc is the first gain parameter, Lsfis the size of the subframe in samples, cw(n) denotes the first shaped excitation signal, xw(n) denotes a Code Excited Linear Prediction encoding signal, wherein the gain parameter controller or the quantizer is further configured for normalizing the first gain parameter to acquire a normalized first gain parameter based on: g nc = g c . \u2211 n = 0 Lsf - 1 \ue89e \ue89e c \ue8a0 ( n ) \u00b7 c \ue8a0 ( n ) Lsf \u00b7 wherein g nc  denotes the normalized first gain parameter and   is a measure for an average energy of the unvoiced residual signal over the whole frame; and wherein the quantizer is configured for quantizing the normalized first gain parameter to acquire the quantized first gain parameter.
