* Silence MSVC C4244 warningMarcus Asteborg2022-07-121-1/+1
| | | | | | When building with FLOAT_APPROX. Signed-off-by: Mark Harris <mark.hsj@gmail.com>
* Fix float-approx negative left shift UBMark Harris2021-01-231-2/+2
| | | | Reported by toto.
* Adding ENABLE_HARDENINGJean-Marc Valin2018-03-271-1/+1
| | | | Enables "safes" assertions even with ENABLE_ASSERTIONS isn't set
* Fix #undef of constantJean-Marc Valin2017-10-081-1/+1
| | | | Reported in https://github.com/xiph/opus/issues/55
* Fixes problem with M_PIJean-Marc Valin2016-08-111-2/+3

* Making stereo_itheta() use the same atan2() approximation as tonality_analysis()Jean-Marc Valin2016-08-111-0/+31
|
* Replace "inline" with OPUS_INLINE.Gregory Maxwell2013-10-281-11/+11
| | | | | | | | | Newer versions of MSVC are unhappy with the strategy of the build environment redefining "inline" (even though they don't support the actual keyword). Instead we define OPUS_INLINE to the right thing in opus_defines.h. This is the same approach we use for restrict.
* Replaces log2() with celt_log2() and fixes a potential divide-by-zeroJean-Marc Valin2013-10-011-0/+1
|
* Converts denormalise_bands() to use 16-bit multiplicationsJean-Marc Valin2013-06-161-2/+8
|
* celt_maxabs16() now returns an opus_val32 to avoid problems with -32768Jean-Marc Valin2013-05-181-2/+2
|
* Should make celt_maxabs*() slightly fasterJean-Marc Valin2012-11-121-4/+12
| | | | shorter dependencies
* Implements OPUS_{GET,SET}_LSB_DEPTHJean-Marc Valin2012-07-131-21/+27
| | | | | This is used to avoid dynalloc doing silly things on periodic LSB patterns and to reduce the bitrate on near-silence.

| * s/FOUNDATION/COPYRIGHT OWNER/ in CELT code and "glue code"Jean-Marc Valin2012-04-201-2/+2
| | | | | | | | Also added 3rd clause to "master" COPYING file
* | Fixes some overflows in the fixed-point pitch codeJean-Marc Valin2012-04-061-0/+11
|/ | | | | | | | | | | The overflows reported were: - Syy in find_best_pitch() in pitch.c - xy, xx and yy in remove_doubling() in pitch.c The fixes are: - Adaptive scaling in pitch_downsample() which also improves quality - Adding a missing downshift in find_best_pitch() - More conservative yshift when calling find_best_pitch()

* Support for glitchles mode switchingJean-Marc Valin2011-03-071-5/+18
| | | | | | Uses a 5ms redundant CELT frame embedded into the SILK or hybrid packet to handle the switching. It's still possible to use the PLC-based method when no redundant packet is included.
