摘要： An audio decoder comprises an arithmetic decoder for providing a plurality of decoded spectral values on the basis of an arithmetically-encoded representation of the spectral values and a frequency-domain to time-domain converter for providing a time-domain audio representation using the decoded spectral values, in order to obtain a decoded audio information. The arithmetic decoder is configured to derive a group index from a variable-length-codeword representing the group index in dependence on a state index. The arithmetic decoder is configured to derive the values of a most-significant bit-plane of a tuple of spectral values using the group index and an element index, and to provide a tuple of decoded spectral values using the values of the most-significant bit-plane of the tuple of spectral values. The arithmetic decoder is configured to select a cumulative-frequencies-table out of a set of 32 cumulative-frequencies-tables in dependence on the state index, and to apply the selected cumulative-frequencies-table to derive the group index from the variable-length codeword representing the group index.

摘要： In accordance with a first aspect of the present invention, bitstream elements of sub-frames are encoded differentially to a global gain value so that a change of the global gain value of the frames results in an adjustment of an output level of the decoded representation of the audio content. Concurrently, the differential coding saves bits otherwise occurring when introducing a new syntax element into an encoded bitstream. Even further, the differential coding enables the lowering of the burden of globally adjusting the gain of an encoded bitstream by allowing the time resolution in setting the global gain value to be lower than the time resolution at which the afore-mentioned bitstream element differentially encoded to the global gain value adjusts the gain of the respective sub-frame. In accordance with another aspect, a global gain control across CELP coded frames and transform coded frames is achieved by co-controlling the gain of the codebook excitation of the CELP codec, along with a level of the transform or inverse transform of the transform coded frames. According to even another aspect, a variation of the loudness of a CELP coded bitstream upon changing the respective gain value is rendered more well adapted to the behavior of transform coded level adjustments, by performing the gain value determination in CELP coding in the weighted domain of the excitation signal.
摘要翻译：根据本发明的第一方面，子帧的比特流元素被差分地编码为全局增益值，使得帧的全局增益值的改变导致对解码表示的输出电平的调整音频内容。同时，差分编码保存在将新的语法元素引入到编码比特流中时所发生的位。此外，差分编码能够通过在将全局增益值设定为低于上述比特流元素差分编码的时间分辨率的同时允许时间分辨率来降低全局调整编码比特流的增益的负担全局增益值调整相应子帧的增益。根据另一方面，跨CELP编码帧和变换编码帧的全局增益控制通过共同控制CELP编解码器的码本激励的增益以及变换编码帧的变换或逆变换的级别来实现。根据另一方面，通过在加权域中的CELP编码中执行增益值确定，在改变相应增益值时，CELP编码比特流的响度的变化被更好地适应于变换编码电平调整的行为激励信号。

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.
摘要翻译：可用于跳过的帧要素可以通过布置在配置块内分开发送默认有效载荷长度信息来更有效地传送，帧元素内的长度信息依次被细分为默认有效载荷长度标志接下来，如果未设置默认有效载荷长度标志，则通过有效载荷长度值显式地编码相应帧元素的有效载荷长度。然而，如果设置了默认有效载荷长度标志，则可以避免有效载荷长度的显式传输。相反，其默认扩展有效负载长度标志被设置的任何帧元素具有默认有效载荷长度，并且其默认扩展有效载荷长度标志未被设置的任何帧元素具有对应于有效载荷长度值的有效载荷长度。通过这种措施，传输效率提高。

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.
