2014-10-04 | There are no tabs in source code. | Timothy B. Terriberry | |
There is also no trailing whitespace. | |||
2014-10-04 | Cisco optimization for x86 & fixed point | xiangmingzhu | |
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.

2013-09-17 | Remove trailing whitespace from the license headers. | Ralph Giles | |
2013-05-20 | Convert quotes in license headers to ASCII. | Timothy B. Terriberry | |
Since the last patch originally had them mangled (presumably by mailer, http server, or something else), let's just get rid of them. | |||
2012-04-21 | License update using the IETF Trust flavour of the BSD on the Silk code | Jean-Marc Valin | |
2011-12-14 | Accuracy improvements to help float implementations | Koen Vos | |
Also clamps the gain to avoid forcing a float decoder to emulate the state rescaling. | |||
2011-12-13 | Improves the accuracy such that it matches a float decoder much better | Koen Vos | |
2011-12-13 | SILK fixes following last codec WG meeting | Koen Vos | |
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 | |||

2011-10-20 | Implements hard CBR for SILK | Jean-Marc Valin | |
This is achieved by running the encoding process in a loop and padding when we don't reach the exact rate. It also implements VBR-with-cap, which means we no longer need to artificially decrease the SILK bandwidth when it's close to the cap. | |||
2011-10-18 | Fix the side frame conditional coding rules. | Timothy B. Terriberry | |
b24e5746 introduced changes to LastGainIndex which broke conditional coding for side frames after a mid-only frame (i.e., in a 60 ms frame where the side is coded, not coded, then coded again). These rules were a mess in general, however, because the side channel state kept a different nFramesDecoded count from the mid channel state, and had no way to tell if the prior side frame was coded. This patch attempts to rationalize them by moving the conditional coding decision up to the top level, where all this information is available. The first coded side frame after an uncoded side frame now always uses independent coding. If such a frame is also not the first side frame in an Opus frame, then it doesn't include an LTP scaling parameter (because the LTP state is well-defined). | |||

2011-03-17 | DTX fix | Jean-Marc Valin | |
2011-03-08 | Support for glitchles mode switching | Jean-Marc Valin | |
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. | |||
