摘要： An audio decoder for providing a decoded representation of an audio content on the basis of an encoded representation of the audio content comprises a linear-prediction-domain decoder core configured to provide a time-domain representation of an audio frame on the basis of a set of linear-prediction domain parameters associated with the audio frame and a frequency-domain decoder core configured to provide a time-domain representation of an audio frame on the basis of a set of frequency-domain parameters, taking into account a transform window out of a set comprising a plurality of different transform windows. The audio decoder comprises a signal combiner configured to overlap-and-add-time-domain representations of subsequent audio frames encoded in different domains, in order to smoothen a transition between the time-domain representations of the subsequent frames. The set of transform windows comprises one or more windows specifically adapted for a transition between a frequency-domain core mode and a linear-prediction-domain core mode.

摘要： An audio encoder for encoding an audio signal has a first coding branch, the first coding branch comprising a first converter for converting a signal from a time domain into a frequency domain. Furthermore, the audio encoder has a second coding branch comprising a second time/frequency converter. Additionally, a signal analyzer for analyzing the audio signal is provided. The signal analyzer, on the hand, determines whether an audio portion is effective in the encoder output signal as a first encoded signal from the first encoding branch or as a second encoded signal from a second encoding branch. On the other hand, the signal analyzer determines a time/frequency resolution to be applied by the converters when generating the encoded signals. An output interface includes, in addition to the first encoded signal and the second encoded signal, a resolution information identifying the resolution used by the first time/frequency converter and used by the second time/frequency converter.

摘要： In a method for generating a scalable data stream, when a block of output data of a first encoder is present, this block of output data is written into the scalable data stream. If output data of a second encoder is present for a preceding period of time, this output data for the preceding section is written in transmission direction behind the block of output data of the first encoder into the data stream. When the output data of the scalable encoder for the current section is present, the output data of the second encoder is written into the bit stream subsequent to the output data of the first encoder. A determining data block is generated and written into the bit stream delayed by a period of time which corresponds to the size of the bit savings bank of the second encoder. Finally, buffer information is written into the bit stream, which indicates, where the beginning of the output data of the second encoder for the current section regarding the determining data block is, wherein the buffer information corresponds to the bit savings bank level. Thus, it is possible to simply signalize a bit savings bank in a scalable data stream. The maximum size of the bit savings bank may further be adjusted depending on the intended decoder delay and be communicated to a decoder by positioning the determining data block in the scalable data stream without an effort of additional bits in order to reduce the initial delay of the decoder.

Alternatively, an audio data stream with pointers in determination blocks, which point to determination block audio data associated to this determination blocks, but distributed among different data blocks, is converted into an audio data stream, wherein the determination block audio data are combined to contiguous determination block audio data. The contiguous determination block audio data can then be included in a self-contained channel element together with their determination block.

摘要： In a method for generating a scalable data stream from one or several blocks of output data of a first encoder and from one or several blocks of output data of a second encoder a determining data block for a current section of an input signal is written. In addition, output data of the second encoder representing a preceding section of the input signal are written in transmission direction from an encoder to a decoder after the determining data block. When the output data of the second encoder are written for a preceding section of the input signal, the output data of the second encoder are written representing the current section of the input signal. In order to signalize where the output data of the second encoder for the preceding section end and where the output data of the second encoder for the current section begin, buffer information is written into the scalable data stream. By the fact that output data of a preceding section follow a determining data block for the current section, a bit savings bank function may be implemented in the scalable encoder and simply be signalized in the bit stream.

摘要： In a method of producing a scalable data stream of at least two blocks of output data of a first coder and a block of output data of a second coder, wherein the at least two blocks of output data of the first coder together represent a current section of an input signal in the first coder, and wherein the block of output data of the second coder represents the same current section of the input signal, a determination data block for the current section of the input signal is written. In addition, the block of output data of the second coder, in the direction of transfer from a coding device to a decoding device, is written after the determination data block for the current section of the input signal. In addition, at least one block of output data of the first coder, in the direction of transfer, is written in front of the determination data block of the current section of the input signal, whereupon offset information is written into the scalable data stream indicating that the at least one block of output data of the first coder, in the direction of transfer, is in front of the determination data block. Thus a low-delay transfer and decoding of only the first scaling layer can be obtained.
