Abstract  Abstract

Audio decoder device for decoding a bitstream the audio decoder device comprising: a predictive decoder for producing a decoded audio frame from the bitstream wherein the predictive decoder comprises a parameter decoder for producing one or more audio parameters for the decoded audio frame from the bitstream and wherein the predictive decoder comprises a synthesis filter device for producing the decoded audio frame by synthesizing the one or more audio parameters for the decoded audio frame; a memory device comprising one or more memories wherein each of the memories is configured to store a memory state for the decoded audio frame wherein the memory state for the decoded audio frame of the one or more memories is used by the synthesis filter device for synthesizing the one or more audio parameters for the decoded audio frame; and a memory state resampling device configured to determine the memory state for synthesizing the one or more audio parameters for the decoded audio frame which has a sampling rate for one or more of said memories by resampling a preceding memory state for synthesizing one or more audio parameters for a preceding decoded audio frame which has a preceding sampling rate being different from the sampling rate of the decoded audio frame for one or more of said memories and to store the memory state for synthesizing of the one or more audio parameters for the decoded audio frame for one or more of said memories into the respective memory.
