- 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.
