* Decode dynamic range control improvementsJean-Michel Trivi2013-08-271-9/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * AAC-Decoder - Only set the program reference level if it has changed compared to the previous value. This allows setting it on a frame-by-frame basis without limitations. Modified file(s): libAACdec/src/aacdec_drc.cpp libAACdec/src/aacdec_drc.h - Add expiry counter for the program reference level. Modified file(s): libAACdec/src/aacdec_drc.cpp libAACdec/src/aacdec_drc_types.h - Disable scaling of light compression gain values when heavy compression mode is enabled to have the full light compression as fallback if no heavy values are available. Modified file(s): libAACdec/src/aacdec_drc.cpp libAACdec/src/aacdecoder_lib.cpp libAACdec/src/aacdec_drc_types.h - Change initialization and channel disabling to improve start-up behavior in SBR decoder. Modified file(s): libSBRdec/src/sbrdecoder.cpp libSBRdec/src/sbrdec_drc.cpp Bug 9428126 Change-Id: Ie1d3949c53910506da2547d32fe3bf6ee7606eb4
* Disclaimer update, lib version incrementJean-Michel Trivi2013-08-201-1/+1
| | | | | | | | | - Update disclaimer in all source files. - Increment library version in each FDK sub-module. Bug 9428126 Change-Id: I490b96d4ee472246b01483202b0bb4f1e9c2a5d7
* Bug 7170947 Update AAC codecJean-Michel Trivi2012-10-021-12/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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\aacdec_drc.cpp libSBRdec\src\sbrdecoder.cpp libSBRdec\src\sbr_dec.cpp libSBRdec\src\sbrdec_drc.cpp - Align metadata processing with reference implementation. 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. Deleded file(s): libAACenc\src\tns_param.h libAACenc\src\tns_param.cpp * FDK-Library - Added x86 Count Leading Zeros intrinsic. Modified file(s): libFDK\include\clz.h Added file(s): libFDK\include\x86\clz_x86.h - Fixed compilation for MIPS GCC-4.4 and higher. Modified file(s): libFDK\include\mips\cplx_mul.h libFDK\include\mips\fixmul_mips.h Change-Id: I4be65f07f88d412224c7fddc3f054e8f451176cc
