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. Modified file(s): libAACenc/include/aacenc_lib.h libAACenc/src/aacenc.cpp libAACenc/src/aacenc.h libAACenc/src/aacenc_lib.cpp libAACenc/src/qc_main.cpp libMpegTPEnc/src/tpenc_latm.cpp libMpegTPEnc/src/version * FDK-Sources - Code clean up. Remove unneeded pseudo audio object types and transport types. Modified file(s): libAACdec/src/aacdecoder.cpp libAACdec/src/aacdecoder_lib.cpp libAACenc/include/aacenc_lib.h libAACenc/src/aacenc.cpp libAACenc/src/aacenc_lib.cpp libFDK/src/FDK_tools_rom.cpp libMpegTPDec/src/tpdec_lib.cpp libMpegTPDec/src/version libMpegTPEnc/src/tpenc_latm.cpp libMpegTPEnc/src/version libSBRdec/src/sbrdecoder.cpp libSBRenc/src/sbr_encoder.cpp libSYS/include/FDK_audio.h libSYS/src/genericStds.cpp Change-Id: I807a53cb7f48c9ee7563cb8da1d0c52221576ca6
