SBR/AAC encoder updates, code clean up
* SBR-Encoder
- Prevent noise level overflow in noise floor detection.
- Saturate threshold calculation in transient detection.
Modified file(s):
libSBRenc/src/nf_est.cpp
libSBRenc/src/sbr_encoder.cpp
libSBRenc/src/tran_det.cpp
* AAC-Encoder
- Expand input data range of GetInvInt() function. There was an encoder
assert observed in non-default bitrate configuration.
Modified file(s):
libAACenc/src/aacenc_lib.cpp
libAACenc/src/intensity.cpp
libFDK/include/fixpoint_math.h
libFDK/src/FDK_core.cpp
libFDK/src/FDK_tools_rom.cpp
- Make sure that the encoder is stable with regard to very low audio bandwidth
confguration parameter value.
- Fix lowdelay blending for low audio bandwidth.
Modified file(s):
libAACenc/src/aacenc.cpp
libAACenc/src/aacenc_lib.cpp
libAACenc/src/adj_thr.cpp
libAACenc/src/psy_configuration.cpp
libAACenc/src/psy_main.cpp
- Disable pseudo surround flag in case metadata matrix mixdown index is
present in program config element.
Modified file(s):
libAACenc/src/aacenc_lib.cpp
- Enable variable bitrate mode in encoder api.
- Add AACENC_PEAK_BITRATE parameter to encoder api.
- Add AACENC_AUDIOMUXVER parameter to encoder api.
