| * Bug fixes in AAC decoder, AAC encoder, FDK libraryJean-Michel Trivi2012-09-0928-4331/+4235
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Latest code drop from Fraunhofer: * AAC-Decoder - Expanded AAC-LD/ELD decoder TNS max band tables to avoid wrong data access for sampling rates <22kHz and >48kHz. Modified file(s): libAACdec\src\aacdec_tns.cpp libAACdec\src\aac_rom.h libAACdec\src\aac_rom.cpp - Fixed ELD synthesis QMF filterbank scaling for downsampled SBR. Modified file(s): libFDK\src\qmf.cpp * AAC-Encoder - Fixed bit rate limiting for lower limit as introduced in the Delivery 2012-05-11. Modified file(s): libAACenc\include\aacenc_lib.h libAACenc\src\aacenc.h libAACenc\src\aacenc.cpp libSBRenc\src\sbr_rom.h libSBRenc\src\sbr_rom.cpp - Allow negative prediction gain as meaning that there is no coding gain. Make use of scaleValueSaturate in gauss window calculation. Modified file(s): libAACenc\src\aacenc_tns.cpp - Added energy saturation to prevent overflow in short blocks. Modified file(s): libAACenc\src\grp_data.cpp - Perform scalefactor adaption in case quantized lines are out of valid range. Modified file(s): libAACenc\src\quantize.cpp - Interrupt quantization loop when no spectral data is available. Adjustments in bitreservoir adaption. Modified file(s): libAACenc\src\qc_main.cpp - Indroduced dynamic scaling in none missing harmonic energy lowering compensation. Modified file(s): libSBRenc\src\env_est.cpp * FDK-Library - Fixed saturation for negative values in scaleValueSaturate. Modified file(s): libFDK\include\scale.h Change-Id: If830ea65caef6b5554281e4b7a77a8b2e08825ce
* | Make sure AACdynamic_RAM gets allocated aligned to 8 bytesJeffrey Knockel2012-10-251-1/+1
| | | | | | | | | | This fixes assert failures on platforms where malloc doesn't provide 8 byte alignment, such as Win9x.
* | Add support for Workgroup 4 (WG4) channel mappingSergio Ammirata2012-10-053-3/+18
| | | | | | | | | | This is the channel ordering used in DVD Audio, and is the standard used internally in the VLC media player.
* | Revert "Do schur_div with a direct 64 bit division instead of a loop on x86"Martin Storsjo2012-09-141-10/+0
| | | | | | | | | | | | | | | | | | This reverts commit 923f3e95f3e332d26f03cf6782f0ab61596ceef2. The optimized version differed from the original in a few cases (in some cases where the return value turned out to be negative while the original implementation returned a positive value), so revert it for now until it has been analyzed completely.
* | Add an encoder exampleMartin Storsjo2012-09-136-0/+454

* | Do schur_div with a direct 64 bit division instead of a loop on x86Jakub Stachowski2012-09-091-0/+10
| | | | | | | | This speeds up HE-AACv2 encoding from 3.85 s to 3.42 s on a Core i7.

| | * Remove workaround in aac for broken toolchainIrina Tirdea2012-09-032-5/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | aac project forces the system not to include sys/types.h by defining _SYS_TYPES_H_. This is a workaround for broken android toolchain. This is no longer needed in latest android version and can be safely removed. This will also lead to more errors if changes in bionic headers are needed.

| | * Don't try to shift more bits than the variable lengthMartin Storsjo2012-08-101-2/+8
| |/ | | | | | | | | | | | | | | | | | | Shifting by more than (or equal to) the variable length is undefined in C. This caused the quantized spectrum values to go out of range, triggering asserts later. Change-Id: If81b6c8caa7b9c75941ad9d280b686d2069c968c
* | Use a saturating shift to avoid overflowMartin Storsjo2012-09-021-1/+1
| | | | | | | | | | When the shift overflowed, asserts were triggered later, where the values were assumed to be non-negative.
* | Use __builtin_clz instead of default implementation of fixnormz on GCCJakub Stachowski2012-08-141-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | The library contains architecture specific versions of the clz functions for arm and mips, but the fallback C version for other architectures is pretty slow. By using __builtin_clz on GCC (available since GCC 3.4), we get a significant (20-40 %) speedup of the total running time on x86. Speed difference: 5.1 s instead of 8.6 s for AAC-LC 128 kbit/s and 3.8 s instead of 4.9 s for HE-AACv2 32 kbit/s, on an i7.
* | Use saturating adds to avoid overflowMartin Storsjo2012-08-111-2/+2
| | | | | | | | | | When the addition overflowed, asserts were triggered later, where the values were assumed to be non-negative.
* | Use saturating adds in all other similar loops in groupShortData as wellMartin Storsjo2012-08-101-3/+3

* build: declare the project foreign to automakeDiego Elio Pettenò2012-07-116-367/+1
| | | | | | By default automake thinks the project is part of GNU and enforces the presence of some files. By declaring the project foreign, we can remove the 0-sized files.

* Don't link to libstdc++Martin Storsjo2012-07-111-0/+5
| | | | | | | While the source is C++, it doesn't use anything from the C++ runtime, so by building with -fno-exceptions -fno-rtti, the dynamic library doesn't have to be linked to libstdc++. This also simplifies things for users of the static library.
* Allow setting bitrate modes 1-5 tooMartin Storsjo2012-07-111-0/+5

* Add an _enc suffix to the sbr_ram/rom files in libSBRencMartin Storsjo2012-07-113-2/+2
