* Silk CNG adapts faster to received packets with lower gainsFelicia Lim2019-05-311-0/+4
|
* Converting some silk_assert()s into hardening celt_assert()sJean-Marc Valin2018-03-271-1/+1
| | | | | Only converted the ones that are really sure (not signal-dependent) and that shouldn't add much run-time complexity
* Optimize silk_LPC_inverse_pred_gain() for ARM NEONLinfeng Zhang2017-02-141-1/+1
| | | | | | | | The optimization is bit exact with C function. Change-Id: Ib3bdc26a5a4ebe02e7f24be85104e8e9a2a9a738 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
* Eliminate trailing spacesMark Harris2016-11-021-3/+3

* Fixes overflow in CNGJean-Marc Valin2016-07-301-1/+1
| | | | (found through fuzzing)
* cng exitation signal can saturate. Use same scaling as PLC and normal decodingSoren Skak Jensen2016-04-151-29/+32

* There are no tabs in source code.Timothy B. Terriberry2014-10-031-10/+10
| | | | There is also no trailing whitespace.
* Fixes CNG overflows from the previous commitKoen Vos2014-06-201-5/+9

* Fixes CNG to address the DTX issue reported by Gonzalo MarianoKoen Vos2014-06-191-5/+10
| | | | | | | | | | - Bug fix: the CNG synthesis filter output consisted of only the prediction values, now added the input to that. - CNG excitation level now takes into account the level from the PLC (since both PLC and CNG can be active at the same time). - CNG is now called before PLC_glue() to smoothen the transition out of CNG.

* Replace "inline" with OPUS_INLINE.Gregory Maxwell2013-10-281-1/+1
| | | | | | | | | 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 Giles2013-09-161-1/+1
|
* Convert quotes in license headers to ASCII.Timothy B. Terriberry2013-05-191-1/+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. Terriberry2013-05-081-1/+6
| | | | | | | | | | | 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 implementationsKoen Vos2011-12-141-5/+5
| | | | | Also clamps the gain to avoid forcing a float decoder to emulate the state rescaling.
* Improves the accuracy such that it matches a float decoder much betterKoen Vos2011-12-131-2/+4

* SILK fixes following last codec WG meetingKoen Vos2011-12-131-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
