| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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.

* 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.
