| * Bug fixes in AAC decoder, AAC encoder, FDK libraryJean-Michel Trivi2012-09-098-151/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
| * 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

* 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.
* 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 saturating adds in all other similar loops in groupShortData as wellMartin Storsjo2012-08-101-3/+3

* 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.
* Use saturating adds to avoid overflowMartin Storsjo2012-08-102-3/+3
| | | | These additions can overflow, triggering assertions later.
* Allow setting bitrate modes 1-5 tooMartin Storsjo2012-07-111-0/+5
| | | | These correspond to different VBR modes.
* Add NOTICE file. Rework make file so it appears in settings.Dave Burke2012-06-122-54/+0

* Added license boilerplate to all source files.Dave Burke2012-06-1175-1293/+5882
| | | | | | | | | Change-Id: I42a702487e6db4953dca0027710ea4fe266052fd Also: - Removed dead code in several source files. - Minor changes in comments. - No functional changes. No changes in executed code. - Added documentation PDFs.
* Update to 2012_05_11 version.Dave Burke2012-05-125-71/+252
| | | | | | | | | | Fixes: - Don't throw error for invalid bitrate but limit to functional value - More robust ASC parsing - More robust handling of corrupt bitstreams - Handle multiple raw access units Change-Id: Ib49fe2545ff4185fe924126da702fe84ac5c2d87
