-   SBR Decoder overview:
-
-   To achieve a synchronized output signal, the following steps have to be
-   acknowledged in the decoder:
-    - The bitstream parser divides the bitstream into two parts; the AAC
-      core coder part and the SBR part.
-    - The SBR bitstream part is fed to the bitstream de-multiplexer followed
-      by de-quantization The raw data is Huffman decoded.
-    - The AAC bitstream part is fed to the AAC core decoder, where the
-      bitstream data of the current frame is decoded, yielding a time domain
-      audio signal block of 1024 samples. The block length could easily be
-      adapted to other sizes e.g. 960.
-    - The core coder audio block is fed to the analysis QMF bank using a
-      delay of 1312 samples.
-    - The analysis QMF bank performs the filtering of the delayed core coder
-      audio signal. The output from the filtering is stored in the matrix
-      Xlow. The output from the analysis QMF bank is delayed tHFGen subband
-      samples, before being fed to the synthesis QMF bank. To achieve
-      synchronization tHFGen = 32, i.e. the value must equal the number of
-      subband samples corresponding to one frame.
-    - The HF generator calculates XHigh given the matrix XLow. The process
-      is guided by the SBR data contained in the current frame.
-    - The envelope adjuster calculates the matrix Y given the matrix XHigh
-      and the SBR envelope data, extracted from the SBR bitstream. To
-      achieve synchronization, tHFAdj has to be set to tHFAdj = 0, i.e. the
-      envelope adjuster operates on data delayed tHFGen subband samples.
-    - The synthesis QMF bank operates on the delayed output from the analysis
-      QMF bank and the output from the envelope adjuster.
