Claim 0:
1. An audio decoder for providing a decoded audio information on the basis of an encoded audio information, the audio decoder comprising:
a linear-prediction-domain decoder configured to provide a first decoded audio information on the basis of an audio frame encoded in a linear prediction domain;
a frequency domain decoder configured to provide a second decoded audio information on the basis of an audio frame encoded in a frequency domain; and
a transition processor,
wherein the transition processor is configured to obtain a zero-input-response of a linear predictive filtering, wherein an initial state of the linear predictive filtering is defined in dependence on the first decoded audio information, and
wherein the transition processor is configured to modify the second decoded audio information, which is provided on the basis of an audio frame encoded in the frequency domain following an audio frame encoded in the linear prediction domain, in dependence on the zero-input-response,
wherein the audio decoder is implemented using a hardware apparatus, or using a computer, or using a combination of a hardware apparatus and a computer.
