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.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.

* Remove __DATE__/__TIME__Dan Willemsen2015-10-231-0/+5
| | | | | | | | | | | | | Building __DATE__/__TIME__ into the binaries means that every build will create different binaries, even if all the sources are identical. This also means that any libraries including this one will need to be patched during every OTA. Nothing appears to use the build_date/build_time fields, so just replace them with empty strings.
