* Rename sbr_rom/ram files back to the original namesMartin Storsjo2012-11-022-0/+0
| | | | This minimizes the differences to upstream.
* Merge remote-tracking branch 'aosp/jb-mr1-release' into masterMartin Storsjo2012-11-014-23/+20

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

* 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.
* Add an _enc suffix to the sbr_ram/rom files in libSBRencMartin Storsjo2012-07-112-0/+0
| | | | | | This avoids name clashes with the similarly named files in libSBRdec, when building all libraries with one single automake file.
* Add NOTICE file. Rework make file so it appears in settings.Dave Burke2012-06-121-35/+0

* Added license boilerplate to all source files.Dave Burke2012-06-1141-791/+3132
| | | | | | | | | 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 Burke2012-05-1217-2323/+743
| | | | | | | | | | 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
