* | Converting some silk_assert()s into hardening celt_assert()s | Jean-Marc Valin | 2018-03-27 | 1 | -3/+3 |
| | | | | | Only converted the ones that are really sure (not signal-dependent) and that shouldn't add much run-time complexity | ||||

* | Remove commented-out DEBUG_STORE_DATA calls. r=keon | Ralph Giles | 2016-11-10 | 1 | -1/+0 |
| | | | | | | | | | | | | | | Also remove the SILK_DEBUG_STORE_CLOSE_FILES flush call from opus_demo. This is debugging code which is no longer used, but defining the symbols for SILK_DEBUG_STORE_CLOSE_FILES and calling it from opus_demo causes linking problems on Microsoft Visual Studio where we have strict controls on public symbols and want to test the compiled DLL. Since the code isn't in active use, it's better to remove it to avoid clutter and address the linking issue. | ||||

* | Cisco optimization for x86 & fixed point | xiangmingzhu | 2014-10-03 | 1 | -3/+10 |
| | | | | | | | | | | 1. Only for fixed point on x86 platform (32bit and 64bit, uses SIMD intrinsics up to SSE4.2) 2. Use "configure --enable-fixed-point --enable-intrinsics" to enable optimization, default is disabled. 3. Official test cases are verified and passed. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org> | ||||
* | Replace "inline" with OPUS_INLINE. | Gregory Maxwell | 2013-10-28 | 1 | -4/+4 |
| | | | | | | | | | 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. | ||||
* | Remove trailing whitespace from the license headers. | Ralph Giles | 2013-09-16 | 1 | -1/+1 |
| | |||||
* | Convert quotes in license headers to ASCII. | Timothy B. Terriberry | 2013-05-19 | 1 | -1/+1 |
| | | | | | | Since the last patch originally had them mangled (presumably by mailer, http server, or something else), let's just get rid of them. | ||||
* | Use dynamic stack allocation in the SILK encoder. | Timothy B. Terriberry | 2013-05-08 | 1 | -3/+10 |
| | | | | | | | | | | | This makes all remaining large stack allocations use the vararray macros. This continues the work of 6f2d9f50 to allow compiling with NONTHREADSAFE_PSEUDOSTACK to move the memory for large buffers off the stack for devices where it is very limited. It also does this for some additional large buffers used by the PLC in the decoder. | ||||

* | Accuracy improvements to help float implementations | Koen Vos | 2011-12-14 | 1 | -63/+63 |
| | | | | | Also clamps the gain to avoid forcing a float decoder to emulate the state rescaling. | ||||

* | SILK fixes following last codec WG meeting | Koen Vos | 2011-12-13 | 1 | -49/+50 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | decoder: - fixed incorrect scaling of filter states for the smallest quantization step sizes - NLSF2A now limits the prediction gain of LPC filters encoder: - increased damping of LTP coefficients in LTP analysis - increased white noise fraction in noise shaping LPC analysis - introduced maximum total prediction gain. Used by Burg's method to exit early if prediction gain is exceeded. This improves packet loss robustness and numerical robustness in Burg's method - Prefiltered signal is now in int32 Q10 domain, from int16 Q0 - Increased max number of iterations in CBR gain control loop from 5 to 6 - Removed useless code from LTP scaling control - Optimization: smarter LPC loop unrolling - Switched default win32 compile mode to be floating-point resampler: - made resampler have constant delay of 0.75 ms; removed delay compensation from silk code. - removed obsolete table entries (~850 Bytes) - increased downsampling filter order from 16 to 18/24/36 (depending on frequency ratio) - reoptimized filter coefficients | ||||

| | | | | | | 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. | ||||
