Abstract:
An apparatus for generating an error concealment signal, includes: an LPC representation generator for generating a replacement LPC representation; an LPC synthesizer for filtering a codebook information using the replacement LPC representation; and a noise estimator for estimating a noise estimate during a reception of good audio frames, wherein the noise estimate depends on the good audio frames representation generator is configured to use the noise estimate estimated by the noise estimator in generating the replacement LPC representation.

Claim (Index 12):
The apparatus of  claim 11 ,\n wherein the LPC representation generator is configured to calculate the replacement LPC representation based on the following equation:\n isf B \u22121 =alpha B \u00b7isf \u22122 +(1\u2212beta)\u00b7 isf cng , \n wherein the LPC representation generator is configured to calculate the further replacement LPC representation based on the following equation: isf \u2032 = isf - 2 + isf - 3 + isf - 4 3 isf A - 1 = alpha A \u00b7 isf - 2 + ( 1 - alpha ) \u00b7 isf \u2032 , wherein \u03b1 A  and \u03b1 B  are time-varying fading factors, wherein ISF \u22122  is the LPC representation of the last good frame, wherein isf \u22123  is the LPC representation of the second last good frame, wherein isf \u22124  is the LPC representation of the third last good frame, wherein isf B \u22121  is the replacement LPC representation, and wherein isf A \u22121  is the further replacement LPC representation, wherein ISF stands for values in an ISF domain or in an LSF domain.
