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.
2020-12-09docs: fix simple typo, neareast -> nearestTim Gates
There is a small typo in celt/fixed_generic.h. Should read `nearest` rather than `neareast`. Signed-off-by: Ralph Giles <giles@thaumas.net>
2017-02-27Fix compiler warningsMark Harris
- celt/modes.c:430:14: warning: cast from 'const unsigned char *' to 'opus_int16 *' increases required alignment from 1 to 2 [-Wcast-align] - 'C[0][1]' may be used uninitialized [-Wmaybe-uninitialized] - Unused variable/parameter - Value stored is never read - MSVC warnings about "possible loss of data" due to type conversions - MSVC warning C4146: unary minus operator applied to unsigned type - silk/NLSF_del_dec_quant.c:137:20: warning: array subscript is above array bounds [-Warray-bounds] (gcc -O3 false positive) - src/mlp_train.h:39:20: warning: function declaration isn't a prototype [-Wstrict-prototypes] - Remove SMALL_FOOTPRINT code from SSE 4.1 FIR implementation, matching the C implementation. The clang -Wcast-align warnings with SSE intrinsics are a known clang issue: https://llvm.org/bugs/show_bug.cgi?id=20670

2013-09-07First pass at making the analysis code run with FIXED_POINTJean-Marc Valin
Code is still float, but at least tonality esitmation seems to work. Speech/music analysis is still disabled.
2013-08-29Implements fixed-point silk_LPC_analysis_filter() in terms of celt_fir()Jean-Marc Valin
Saves 2.5% on ARM without any asm. The float build still uses the old code because celt_fir() then becomes a float function.
2013-05-22Minor ARMv5E cleanups.Timothy B. Terriberry
Missed the armv5e extension on a couple of functions.
2012-07-11Add OPUS_{GET|SET}_GAIN CTLs for adjusting output gain.Gregory Maxwell
This CTL was requested by Nicolas George for FFmpeg.

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.
