From Fraunhofer:
* AAC Decoder
- Stick to the written MPEG standard instead of the MPEG reference software
in terms of reference level normalization. Always set the program reference
level equal to the target level. This disables level normalization using a
default level for streams without embedded metadata.
Modified file(s):
libAACdec\src\aacdec_drc.cpp
- Fix downmix channel assignment when using a WAV output channel ordering.
Modified file(s):
libPCMutils\src\pcmutils_lib.cpp
- Retain signal accuracy and prevent LSB alteration when no level correction
needs to be done.
