2016-08-05Partially collapsing the stereo image when channels have different energyexp_stereo5Jean-Marc Valin
We can lower the distortion of the most important channel, at the expense of the other channel.
2016-08-05biasing quantizationJean-Marc Valin
2016-08-05Weighting theta rdo based on channel energyJean-Marc Valin
2016-07-30Fixes overflow in CNGJean-Marc Valin
(found through fuzzing)
2016-07-28Don't do theta RDO on intensity-stereo-coded bandsJean-Marc Valin
2016-07-28Saving the state rather than re-compute the best optionJean-Marc Valin
2016-07-28Making stereo theta decision based on minimizing distortionJean-Marc Valin
No point in minimizing the rate too since it's almost constant.
2016-07-28controlling roundingJean-Marc Valin
2016-07-28Properly allocation scratch space for resynth encoderJean-Marc Valin
2016-07-28cleanup: putting resynth flag in the contextJean-Marc Valin
2016-07-28cleanup: line wrappingJean-Marc Valin

2016-07-27appveyor: Package includes and opus.lib as an artifact.Ricardo Constantino (:RiCON)
This lets projects which depend on opus build against our test results. Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-27VS2015: Ignore warning 4146 in celt/kiss_fft.c.Ricardo Constantino (:RiCON)
Warning 4146 is "unary minus operator applied to unsigned type, result still unsigned" Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-27win32/.gitignore: Add DebugDLL_fixed.Ricardo Constantino (:RiCON)
Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-27VS2015: Disable building DebugDLL opus_demo.Ricardo Constantino (:RiCON)
This works around the issue with using private symbols. Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-27vs2015: Merge opus dependencies into its project.Ricardo Constantino (:RiCON)
Since DLL builds can't include both fixed and float, separate DLL_fixed configurations added that include fixed silk code and also set FIXED_POINT. Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-26VS2015: Mirror changes in *.mk files from exp_lbr_tune merge.Ricardo Constantino (:RiCON)
Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-26Trim appveyor config.Ralph Giles
2016-07-26Add appveyor.yml to test VS2015 builds.Ricardo Constantino (:RiCON)
Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-26VS2015: Suppress a few warnings.Ricardo Constantino (:RiCON)
SDLCheck is a superset of BufferSecurityCheck and is off by default. If it's set, it complains that it's overriden by BufferSecurityCheck. Warning 4996 is already ignored in other binaries (fopen being deprecated and suggesting fopen_s). NoExtensions isn't a valid value for EnableEnhancedInstructionSet in x64 builds.
2016-07-26Create a simple project to create version.h.Ricardo Constantino (:RiCON)
Run before any other project. Avoids trying to create and replace version.h more than once which led to file-locking errors with multicore builds. Signed-off-by: Ralph Giles <giles@mozilla.com>
2016-07-25Disabling the use of celt_fir() in silk_LPC_analysis_filter() by defaultJean-Marc Valin
2016-07-25Fixes an overflow in limit_warped_coefs()Jean-Marc Valin
For large values of maxabs_Q20, silk_MUL( maxabs_Q20, ind + 1 ) could overflow.
2016-07-25Move PLC LPC bandwidth expansion before the FIR to avoid overflows in celt_fir()Jean-Marc Valin
2016-07-25Fixes commentJean-Marc Valin
2016-07-25Fixes an overflow in amp2Log2() for very large encoder inputJean-Marc Valin
2016-07-25Fixes cap on gain in denormalise_bands()Jean-Marc Valin
2016-07-25Fixes a shift<0 issue in transient_analysis()Jean-Marc Valin
Fixes a potential overflow in high-passed signal for transient detection and ensures that the shift can never go negative
2016-07-25Tighter bound in filter control in PLCJean-Marc Valin
We can't use the attenuation since it doesn't apply to the memory
2016-07-25More headroom in PLC codeJean-Marc Valin
extrapolation_len can be up to 960+120, so we we need a shift of 10 if the values are very large.
2016-07-25Saturate MDCT output post-TDAC rather than pre-Jean-Marc Valin
Gives us a tighter bound on the pitch postfilter input to avoid overflows
2016-07-25Avoids reading beyond the current buffer in comb_filter()Jean-Marc Valin
This could cause overflows when processing non-saturated TDAC values.
2016-07-24Directly saturate the comb filter outputJean-Marc Valin
Otherwise, the output can grow as large as SIG_SAT/(1-0.75), which can cause an overflow when adding two values (before multiplying by the filter tap).
2016-07-22Avoiding an overflow in the LTP quantizationJean-Marc Valin
Reduces the XX values to avoid an overflow in silk_VQ_WMat_EC(), even in floating-point.
2016-07-22Disables MIPS silk_noise_shape_analysis_FIX() until it's updatedJean-Marc Valin
2016-07-22More headroom in fixed-point silk_burg_modified() to avoid an overflowJean-Marc Valin
2016-07-22Increase headroom in silk_warped_autocorrelation_FIX()Jean-Marc Valin
2016-07-22Increase headroom to avoid overflow in silk_pitch_analysis_core()Jean-Marc Valin
2016-07-22PLC overflow fixJean-Marc Valin
2016-07-22Prevent overflows in PLC celt_iir()Jean-Marc Valin
2016-07-22fixes overflows in celt_iir() by doing proper saturationJean-Marc Valin
2016-07-22getting rid of a PLC overflow (I think)Jean-Marc Valin
2016-07-22post-filter saturationJean-Marc Valin
2016-07-22saturate MDCT outputJean-Marc Valin
2016-07-22silencing overflows in MDCT and FFTJean-Marc Valin
2016-07-22Reduce risk of overflowing in mono downsamplingJean-Marc Valin
Not observed yet (except when caused by a different bug), but "just in case"
2016-07-22Avoid overflowing on ridiculously large energyJean-Marc Valin
2016-07-22Fixes shift<-2 case for denormalise_bands()Jean-Marc Valin
