    摘要： A better compromise between a too high bitstream and decoding overhead on the one hand and flexibility of frame element positioning on the other hand is achieved by arranging that each of the sequence of frames of the bitstream comprises a sequence of N frame elements and, on the other hand, the bitstream comprises a configuration block comprising a field indicating the number of elements N and a type indication syntax portion indicating, for each element position of the sequence of N element positions, an element type out of a plurality of element types with, in the sequences of N frame elements of the frames, each frame element being of the element type indicated, by the type indication portion, for the respective element position at which the respective frame element is positioned within the sequence of N frame elements of the respective frame in the bitstream. Thus, the frames are equally structured in that each frame comprises the same sequence of N frame elements of the frame element type indicated by the type indication syntax portion, positioned within the bitstream in the same sequential order. This sequential order is commonly adjustable for the sequence of frames by use of the type indication syntax portion which indicates, for each element position of the sequence of N element positions, an element type out of a plurality of element types.

    摘要： Frame elements which shall be made available for skipping may are transmitted more efficiently by arranging that a default payload length information is transmitted separately within a configuration block, with the length information within the frame elements, in turn, being subdivided into a default payload length flag followed, if the default payload length flag is not set, by a payload length value explicitly coding the payload length of the respective frame element. However, if the default payload length flag is set, an explicit transmission of the payload length may be avoided. Rather, any frame element, the default extension payload length flag of which is set, has the default payload length and any frame element, the default extension payload length flag of which is not set, has a payload length corresponding to the payload length value. By this measure, transmission effectiveness is increased.

    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.
