2013-09-17Remove trailing whitespace from the license headers.Ralph Giles
2013-05-20Convert 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.
2013-05-08Use dynamic stack allocation in the SILK encoder.Timothy B. Terriberry
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.

2012-03-08Fixes a bunch of 16-bit issues that the C5X compiler warns aboutJean-Marc Valin
2011-12-13SILK fixes following last codec WG meetingKoen 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
2011-10-29Reformatting changes with an update to the MSVC project filesKoen Vos
2011-10-12Misc bug fixesJean-Marc Valin
- There was a bug where the decoder resampler was not properly initialized when fs_kHz == API_fs_kHz. In that case the resampler would continue to upsample, and the output was corrupt. - The delay value in the decoder was taken from the state before it was potentially updated. This caused the decoder to apply the new dalay value one frame late - The encoder and decoder states are now updated more consistently, when the sampling rate changes (pesq liked these changes) - Properly resetting the side channel encoder and decoder for the first frame with side coding active again - Faster updating the "ratio" value in the LR_to_MS() code for large prediction values means that for certain extreme/artificial input signals the output looks better
2011-10-10Cleaner way to take into account the prediction for stereo widthKoen Vos
2011-10-09Avoids unnecessary collapse of the HF stereo image in hybrid mode.Jean-Marc Valin
SILK now reports an "effective width" that takes into account side prediction.
2011-10-08Prevents a SILK stereo encoding-side desyncJean-Marc Valin
We now make sure that side is given >0 bits when it isn't disabled.
2011-10-06SILK updateKoen 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
2011-10-05SILK stereo fixKoen Vos
Fixes a mono-stereo switching glitch and fixes a side prediction bug where coding side would result in worse panned-mono behaviour

2011-03-08Support for glitchles mode switchingJean-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.
