a prior change reduced iterations through the input buffer to avoid the NEON operations from overrunning the end of the locally allocated buffer. While avoiding the overrun, it generated bad results. Here we instead extend the locally allocated buffers enough that the original iteration count won't overrun. Some pre-existing bit-exact issues remain. Bug: 136616344 Test: CTS + bit-exact cross-checks.

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.
2018-05-17Improving 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.

2017-06-13Fix a duplicate symbol name.Ralph Giles
