2014-01-07 | Store decoded SILK pulses as 16-bit vector | Jean-Marc Valin | |
This saves 640 bytes on the peak stack usage. | |||
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. | |||
2012-09-08 | Use dynamic stack allocations in SILK decoder. | Timothy B. Terriberry | |
This allows the decoder to be compiled with NONTHREADSAFE_PSEUDOSTACK to move the memory for large buffers off the stack for devices where it is very limited. This patch only attempts to do this for the decoder. The encoder still requires more than 10 kB of stack. | |||
2012-04-24 | Merge commit '390c89225d' | Jean-Marc Valin | |
2012-04-21 | License update using the IETF Trust flavour of the BSD on the Silk code | Jean-Marc Valin | |
2012-03-08 | Fixes a bunch of 16-bit issues that the C5X compiler warns about | Jean-Marc Valin | |
2012-01-31 | Last part of the LPC work stabilization work discussed at the last meeting | Koen Vos | |
Also adds the encoder part of commit ee8adbe701 as well as a few minor cleanups. | |||
2012-01-24 | Fixes a few minor issues (no bit-stream change) | Jean-Marc Valin | |
- Safer gain clamping for PLC - Makes opus_decoder_get_nb_samples() report an error on invalid ToC - Giving a free license to the text ofthe draft (not just the code) | |||
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 | |||
2011-10-29 | Reformatting changes with an update to the MSVC project files | Koen Vos | |
2011-10-11 | Misc SILK fixes: | Koen Vos | |
- compile warning in opus_decoder.c - decoder state reduced by ~3 kB (by merging buffers, as Tim suggested) - some minor decoder optimizations (only the PLC is non-bit exact, so should be ok) | |||
2011-10-06 | SILK update | Koen Vos | |
Simplifies mono/stereo switching in SILK Fixes a quantization mismatch between encoder and decoder Constrains the pitch lags in the same way in the encoder and decoder | |||
2011-09-23 | Fixes a decoder overflow on random input | Koen Vos | |
Also some MSVC build fixes | |||
2011-09-16 | Removed all the silk_ prefixes in source file names (not symbols) | Jean-Marc Valin | |
2011-04-29 | Moved all SILK source code to the silk/ directory | Jean-Marc Valin | |
2011-04-28 | Relying on SILK for the switching decisions | Jean-Marc Valin | |
2011-04-28 | SILK makefile update | Jean-Marc Valin | |

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. | |||
