CONCEPT FOR SWITCHING OF SAMPLING RATES AT AUDIO PROCESSING DEVICES

Abstract

an audio decoder device decodes the bit stream of the audio decoder device comprising: a predictive decoder for generate decoded from the bit stream of the audio frame. synthesis filter device wherein predictive decoder comprises one or more audio parameters from the bit stream generation parameter decoder for decoding of the audio frames and wherein the predictive decoder comprises one or more audio parameters for the synthesis for the decoded audio frame to generate a decoded audio frame a memory device. comprises one or a plurality of memories wherein each memory is used for storing the decoded audio frame of memory state and memory state of the audio frame wherein one or more memory for decoded synthesis filter device used for synthesizing audio for decoding of one or more audio parameters and a memory state and sampling device for sampling for the previous memory state synthesizing one or more audio parameters for the previously decoded audio frame by in the memory of one or more; in the memory of the one or more determined to synthetic audio frame for decoding one or more audio parameters of the memory state the decoded audio frame with a sampling rate the previously decoded audio frame with the decoded audio frame sampling rate different from the previous sampling rate and for the one or more of the used in the memory to synthesize one or more audio parameters for the decoded audio frame memory states are stored in the respective memory.

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.
