| | * AArch64: Make LONG 4 bytesMarcus Oakland2014-03-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The libSYS/include/machine_type.h header file states LONG should be "Data type representing 4 byte signed integer on all supported platforms" but only provided for defining LONG as INT and ULONG as UINT when __x86_64__ was defined. This has been changed to when __LP64__ is defined, so that it also applies to AArch64. The change to libFDK/include/common_fix.h is then needed to get the project to compile.

| * | Temporary workaround for 64-bit build errorGlenn Kasten2014-03-121-1/+1
| |/ | | | | | | | | | | Replace #error by #warning so we can build 64-bit Change-Id: Ib52fbfb0e5e945ff04ba51ae06b4e3393886d7b7
* | Extend the GetInvInt table to 80 elementsMartin Storsjo2014-08-012-8/+13
| | | | | | | | | | | | | | | | | | | | This is a bug fix patch from Fraunhofer, amending/replacing/extending the previous commit which only extended the table to 55 elements. (In my previous fix, 55 seemed to be enough for the issue at hand at least. A few of the coefficients had slightly different rounding than what Fraunhofer had used though). This will show up in AOSP in the next code drop as well.
* | Extend GetInvInt to support values up to 54Martin Storsjo2014-07-292-6/+7
| | | | | | | | | | | | | | | | | | For sample rates >= 64 kHz with short blocks, the largest sfb width is 36, which after grouping can be multiplied with 3, ending up as 108. GetInvInt needs to be able to support the largest grouped sfb width, divided by two (3 * 36 / 2 = 54). This fixes VBR encoding with sample rates >= 64 kHz.
* | Add ppc optimization for clz and fixmulMark Harris2014-05-265-1/+232
| | | | | | | | | | Optimize ppc/ppc64 similar to i386/x86_64, approximately doubling encoding speed on a Power Mac G5 running OS X 10.5.8.

* Bug 7170947 Update AAC codecJean-Michel Trivi2012-10-026-10/+196
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Deleded file(s): libAACenc\src\tns_param.h libAACenc\src\tns_param.cpp * FDK-Library - Added x86 Count Leading Zeros intrinsic.
