2017-06-10Improving tonality estimation with delayed decisionJean-Marc Valin
2017-06-09Update releases.sha2Jean-Marc Valin
2017-06-07Clean celt_pitch_xcorr_float_neon()v1.2-rc1Linfeng Zhang
Call celt_inner_prod_neon() and remove redundant code. Change-Id: I980e94330ae75c10297b9035fac221515aee144f Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-06-07Optimize floating-point celt_inner_prod() and dual_inner_prod() for ARM NEONLinfeng Zhang
The floating-point optimizations are not bit exact with C functions, because of the different orders of floating-point operations. But they are bit exact with the simulation C functions which simulate the floating operations in the optimizations. Change-Id: I149fda5b602fd5712b16fc8983df3c6c0c9e76ad Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-06-07Optimize fixed-point celt_inner_prod() and dual_inner_prod() for ARM NEONLinfeng Zhang
This optimization is bit exact with C functions. Change-Id: Ia9ce6dd3c20d2f56dbd43ddc02d1a6fd6554608d Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-06-07Replace call of celt_inner_prod_c() (step 2)Linfeng Zhang
Should call celt_inner_prod(). This requires the API change of celt_pitch_xcorr() by passing in "arch". We tested on x86 and arm, and got bit exact results as original. Change-Id: I606915da6a196f327ce81f4a5ae32811f4c1fabb Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-06-07Replace call of celt_inner_prod_c() (step 1)Linfeng Zhang
Should call celt_inner_prod(). This change is bit exact as original, except for x86 floating-point. In x86 floating-point, it calls celt_inner_prod_sse() which may have different output with the change of floating-point operations' orders. Change-Id: Ia2381e2e198a84296ac28305183f15be842b3454 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-06-05Initialize speech/music prob based on applicationJean-Marc Valin
2017-06-04Properly compute redundancy_bytesJean-Marc Valin
2017-06-04Properly init speech/music confidence valuesJean-Marc Valin
This was sometimes causing the music probability to be stuck at zero at the beginning of files
2017-06-03Don't use MAY_HAVE_NEON in arm_silk_map.c.Jonathan Lennox
It's unnecessary, and isn't defined correctly on floating-point. This makes us correctly use Neon functions (in floating-point mode) on platforms where Neon is detected by RTCD. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
2017-06-02Recalibrate VBR to hit target bitrate on averageJean-Marc Valin
2017-06-02Update dynalloc VBR calibrationJean-Marc Valin
2017-06-02fix commentsJean-Marc Valin
2017-06-01Avoid using log2() since it's not in C90Jean-Marc Valin
2017-06-01Adding leakage modelling to boost bandsexp_leakage7Jean-Marc Valin
We boost bands that either cause leakage or are filled with leakage
2017-06-01Analysis refactoring for fixed-point scalingJean-Marc Valin
Now scaling the energy to the same value is would be in floating-point
2017-06-01Let CBR use more bits for dynallocJean-Marc Valin
It seems like letting CBR use up to 2/3 of the bit is still a win
2017-05-30silk_LIMIT_32() should return an opus_int32 (not opus_int)Jean-Marc Valin
Thanks to petrufm for pointing that out: https://github.com/xiph/opus/issues/35
2017-05-26Fix memory leaks in opus_compare.cJean-Marc Valin
This makes it possible to run the testvectors with asan enabled.
2017-05-26Fixes unit tests that need arch-specific codeJean-Marc Valin
We now include the object files for those rather than attempt to problems.
2017-05-25appveyor: fix typoed appveyor commandRicardo Constantino
And run the build request only at the last configuration. Also add a check if api_key is unset to not try to request a new build. Signed-off-by: Ralph Giles <giles@thaumas.net>
2017-05-25appveyor: Add the api key for the linked ci builds.Ralph Giles
The appveyor script needs an encrypted api key to trigger downstream builds, and there doesn't seem to be an easy way to make the builds we run for the main repo something other contributors can control. Signed-off-by: Ricardo Constantino <wiiaboo@gmail.com>
2017-05-25appveyor: request rebuild of opus-tools on successful buildRicardo Constantino
Using my API key for now, but needs rillian's to work. Signed-off-by: Ralph Giles <giles@thaumas.net>
2017-05-25appveyor: simplify and preserve pathsRicardo Constantino
Artifact with preserved paths is more useful for CI. Signed-off-by: Ralph Giles <giles@thaumas.net>
2017-05-25appveyor: move to dotfile like travisRicardo Constantino
Less clutter on systems that hide dotfiles. Signed-off-by: Ralph Giles <giles@thaumas.net>
2017-05-24Updated SHA256 of releasesJean-Marc Valin
2017-05-24Fixes a double->float conversion warningJean-Marc Valin
2017-05-24Fixes some fixed-point 16-bit int overflowsv1.2-betaJean-Marc Valin
The code would have run fine on 32-bit archs, but would have overflowed on a 16-bit arch
2017-05-24Reducing trim at low bitrateJean-Marc Valin
Some informal tests seem to confirm that reducing the trim at 32-64 kbps improves quality (better HF). It's not clear whether it's also the case at 96 kb/s and above, so we're leaving it as is for those rates. This corresponds to buildC in this thread: https://hydrogenaud.io/index.php/topic,113985.0.html Also see: https://hydrogenaud.io/index.php/topic,111798.0.html
2017-05-23cosmetics,silk: correct input/output arg commentsLinfeng Zhang
Change-Id: I607a8b75b0711a485384d6f854cf6e2ec18b38b7 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-05-23Fixes a surround bug on loud signalJean-Marc Valin
The constant was copied from the analysis code which uses +/-1 as float scaling, but surround_analysis() uses +/-32767.
2017-05-17Optimize silk_biquad_alt_stride2() for ARM NEONLinfeng Zhang
The optimization is bit exact with C function. Change-Id: Ifb8f04b19f2d576e79ce5dcfa7e0fc374d71d6c8 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-05-17Update silk_biquad_alt()Linfeng Zhang
Split to silk_biquad_alt_stride1() and silk_biquad_alt_stride2(), so that it can be optimized more efficiently when stride is 2. This change in C code is bit exact with the origin. Change-Id: Idaefe670397016ace2a489e3435ac61b7dbe79d5 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>

2017-05-02Avoid warning when __STDC_VERSION__ is not definedCarlos Alberto Lopez Perez
This fixes an issue with gcc 4.9 on Debian 8, at least, which defines __STDC__ but not __STDC_VERSION__, unlike more recent gcc. Signed-off-by: Ralph Giles <giles@thaumas.net>
2017-04-29oops, fix build broken by previous patchJean-Marc Valin
2017-04-29Non-diegetic support for Ambisonics Mapping 254.Drew Allen
Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-04-14Optimize silk_warped_autocorrelation_FIX() for ARM NEONLinfeng Zhang
The optimization is bit exact with C function. This optimization speeds up fixed-point SILK encoder on NEON about 5% to 8%. (Tested on Acer Chromebook, ARMv7 Processor rev 3 (v7l).) Change-Id: I582f6f3585b7946149e16a2ad3084ebc0ae79a4f Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-03-27Fix OPUS_ARG_NONNULL indices in opus_multistream.hFelicia Lim
2017-03-03VS2015: remove previously ignored C4146 in kiss_fft.cRicardo Constantino
C4146: unary minus operator applied to unsigned type, result still unsigned Fixed in a previous commit. Signed-off-by: Mark Harris <mark.hsj@gmail.com>
2017-03-03VS2015: Ignore LNK4221 and properly force SSE off for Win32Ricardo Constantino
This warning complains of files that don't define any new symbols not being included in linking. GCC doesn't seem to complain about those, so neither should VS. Signed-off-by: Mark Harris <mark.hsj@gmail.com> Closes https://github.com/xiph/opus/pull/34
2017-03-03VS2015: ignore C4244 warning in opus_compare.cRicardo Constantino
opus_compare.c defines the bitstream so we avoid changing it by ignoring the non-breaking warning instead of changing the file. Signed-off-by: Mark Harris <mark.hsj@gmail.com> Resolves https://github.com/xiph/opus/issues/21
2017-02-27Fix compiler warningsMark Harris
- celt/modes.c:430:14: warning: cast from 'const unsigned char *' to 'opus_int16 *' increases required alignment from 1 to 2 [-Wcast-align] - 'C[0][1]' may be used uninitialized [-Wmaybe-uninitialized] - Unused variable/parameter - Value stored is never read - MSVC warnings about "possible loss of data" due to type conversions - MSVC warning C4146: unary minus operator applied to unsigned type - silk/NLSF_del_dec_quant.c:137:20: warning: array subscript is above array bounds [-Warray-bounds] (gcc -O3 false positive) - src/mlp_train.h:39:20: warning: function declaration isn't a prototype [-Wstrict-prototypes] - Remove SMALL_FOOTPRINT code from SSE 4.1 FIR implementation, matching the C implementation.

2017-02-21VS2015: Move back PreprocessorDefinitions to opusRicardo Constantino
They're only needed in that project, no need to be in common.props. Signed-off-by: Mark Harris <mark.hsj@gmail.com>
2017-02-21VS2015: join common options in a properties fileRicardo Constantino
Should make the projects a bit easier to digest and the differences between the different configurations and platforms be more obvious. A (happy?) side effect of this is the static libraries are now about the same size as the ones produced by GCC and seem to build fine with opus-tools. Needs testing with other third party applications to make sure nothing is missing that shouldn't. Signed-off-by: Mark Harris <mark.hsj@gmail.com>
2017-02-21VS2015: remove dead options for linker in static configurationsRicardo Constantino
