2022-08-05Change pitch scaling behavior wrt nFramesPerPacketJean-Marc Valin
Not sure if it was the original intent, but we now reduce the loss percentage threshold for pitch scaling as 1/nFramesPerPacket since only the first frame will have pitch scaling anyway. As a side effect, this brings back the original behavior of disabling pitch scaling for 0% loss.

2022-07-24Re-tuning the use of LTP scalingJean-Marc Valin
Making LTP scaling depend on the bitrate and whether FEC is on. The thresholds for scaling 1 and 2 are now independent.

2022-06-28Fixes valgrind failure caused by silk_find_pred_coefs_*()Jean-Marc Valin
The function copies NLSFs from the stack to the state which for order 10 means we were copying uninitialized values. That in turn breaks check-asm when comparing the state under valgrind. Reviewed by Timothy B. Terriberry.

2021-03-03celt_lpc: avoid overflows when computing lpcs in fixed pointFelicia Lim
The LPCs are computed in 32-bit, so increase the allowed range from +/-8 to +/-64 to avoid overflows caught during fuzzing. Before downshifting back down to the +/-8 range in the final 16-bit output, perform bandwidth extension to avoid any additional overflow issues.

2018-05-24Fixes a SILK bandwidth switching regressionJean-Marc Valin
The bug was triggered because f982b84d started using prefill for SILK bandwidth changes, which reinitialized the encoder state and prevented the variable lowpass from working properly. To fix the problem, we preserve the sampling rate and variable low-pass when prefilling.
2018-05-18Improving rate control for low bitrateJean-Marc Valin
Using a finer table for the rate to SNR curves in silk_control_SNR(). It's now possible to have an SNR that reaches 0, so we can lower bitrate down to ~5 kbps for narrowband and 5.5 kbps for wideband.

2017-09-28Better rate allocation for stereo SILK in hybrid modeJean-Marc Valin
SILK was being allocated too few bits for stereo hybrid, often resulting in forced narrowing of the width. We now allocate more bits to SILK and reduce the threshold for narrowing. This improves quality enough that the bitrate threshold for switching to SILK can be increased to 44 kb/s.
