* AAC Decoder: introduce time domain limiterJean-Michel Trivi2014-03-311-2065/+2162
| | | | | | | | | | | | | Introduce time domain limiter. The module is per default enabled for all AAC-LC and HE-AAC v1/2 streams. For all ER-AAC-LD and ER-AAC-ELD streams the limiter is disabled per default. The feature can be en- or disabled via dynamic API parameter. Note that the limiter introduces an additional output delay which depends on the module parameters and the streams sampling rate. Bug 9428126 Change-Id: I299a072340b33e2c324facbd347a72c8de3d380e

* Encoder explicit signalingJean-Michel Trivi2013-09-031-3562/+3650
| | | | | | | | | | | | | | | | | | | | | * AAC-Encoder - Revise explicit signaling method which is required for downsampled SBR. The parameter is optional and default configuration is implicit signaling for dualrate SBR as before. In case of downsampled SBR and HE-AAC explicit signaling is configured as default.

* Bug 7170947 Update AAC codecJean-Michel Trivi2012-10-022-1221/+1225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Modified file(s): libAACdec\src\aacdec_drc.h libAACdec\src\aacdecoder.cpp * AAC-Encoder - Prevent potential overflow in energy calculation after TNS processing. Modified file(s): libAACenc\src\band_nrg.cpp - Added saturation for number of relevant lines which are used in pe calculation. Modified file(s): libAACenc\src\line_pe.cpp - Removed obsolete files.
