Bug fixes in AAC decoder, AAC encoder, FDK library
Latest code drop from Fraunhofer:
* AAC-Decoder
- Expanded AAC-LD/ELD decoder TNS max band tables to avoid wrong data
access for sampling rates <22kHz and >48kHz.
Modified file(s):
libAACdec\src\aacdec_tns.cpp
libAACdec\src\aac_rom.h
libAACdec\src\aac_rom.cpp
- Fixed ELD synthesis QMF filterbank scaling for downsampled SBR.
Modified file(s):
libFDK\src\qmf.cpp
* AAC-Encoder
- Fixed bit rate limiting for lower limit as introduced in the Delivery 2012-05-11.
Modified file(s):
libAACenc\include\aacenc_lib.h
libAACenc\src\aacenc.h
libAACenc\src\aacenc.cpp
libSBRenc\src\sbr_rom.h
libSBRenc\src\sbr_rom.cpp
- Allow negative prediction gain as meaning that there is no coding gain.
Make use of scaleValueSaturate in gauss window calculation.
Modified file(s):
libAACenc\src\aacenc_tns.cpp
- Added energy saturation to prevent overflow in short blocks.
Modified file(s):
libAACenc\src\grp_data.cpp
- Perform scalefactor adaption in case quantized lines are out of valid range.
Modified file(s):
libAACenc\src\quantize.cpp
- Interrupt quantization loop when no spectral data is available.
Adjustments in bitreservoir adaption.
Modified file(s):
libAACenc\src\qc_main.cpp
- Indroduced dynamic scaling in none missing harmonic energy lowering compensation.
Modified file(s):
libSBRenc\src\env_est.cpp
* FDK-Library
- Fixed saturation for negative values in scaleValueSaturate.
Modified file(s):
libFDK\include\scale.h
