* Fix compiler warningsMark Harris2017-02-261-7/+8
| | | | | | | | | | | | | | | | | | | - 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. The clang -Wcast-align warnings with SSE intrinsics are a known clang issue: https://llvm.org/bugs/show_bug.cgi?id=20670

* 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.
* Saturates the last RC to 0.99 when Schur blows upJean-Marc Valin2013-05-161-0/+6
| | | | | This is a follow-up on ac76b15. When Schur blows up, we set the last RC to +/- 0.99 instead of eliminating it.
* Fixes an assertion failure in SILKJean-Marc Valin2013-05-091-1/+9
| | | | | | | | | | We stop the schur recursion before any reflection coefficient goes outside of ]-1,1[ and we force reporting a residual energy of at least 1. Assertion was: Fatal (internal) error in ../silk/fixed/noise_shape_analysis_FIX.c, line 290: assertion failed: nrg >= 0 triggered by: opus_demo voip 16000 1 12500 -bandwidth WB -complexity 10 pl04f087.stp-crash out.pcm
* License update using the IETF Trust flavour of the BSD on the Silk codeJean-Marc Valin2012-04-201-17/+17

* SILK fixes following last codec WG meetingKoen Vos2011-12-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Reformatting changes with an update to the MSVC project filesKoen Vos2011-10-281-4/+4

* Move a number of files and functions which are only used by fixed point ↵Gregory Maxwell2011-10-101-0/+92
| | | | | | builds from silk/ to silk/fixed/. I attempted to not break the msvc projects, but I can't test them.

|
* Support for glitchles mode switchingJean-Marc Valin2011-03-071-5/+5
| | | | | | 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.
