* docs: replace fgrep with grep -FClaudio Saavedra2023-04-201-1/+1

* Make CELT FFT twiddle complex type alignedZheng Lv2023-01-171-1/+11
| | | | | | | | | | | | This makes kiss_twiddle_cpx 4-byte aligned (instead of 2-byte) for fixed-point builds. Tested with an armv6j+nofp development board, CELT encoding becomes 1.4x as fast, and decoding over 2x. Performance gain is mostly attributed to the proper alignment of the static const array mdct_twiddles960. Co-authored-by: David Gao <davidgao@google.com> Signed-off-by: Felicia Lim <flim@google.com>

* Change pitch scaling behavior wrt nFramesPerPacketJean-Marc Valin2022-08-042-2/+2
| | | | | | | | 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.
* Smooth out the LBRR rate estimateJean-Marc Valin2022-07-241-2/+13
| | | | Reduces fluctuations in the non-FEC target bitrate.

|
* Re-tuning the use of LTP scalingJean-Marc Valin2022-07-242-3/+14
| | | | | Making LTP scaling depend on the bitrate and whether FEC is on. The thresholds for scaling 1 and 2 are now independent.

| | | | | | | | MULT16_32_QX() is now implemented using a signed-unsigned multiply, so the second argument can now have one extra bit compared to the old signed-signed implementation. Reviewed by Mark Harris

* cmake - fix lrintf, lrint detectionMarcus Asteborg2022-07-071-9/+20
| | | | | | | | | | | | | This commit addresses the issues of not finding lrintf and lrint. We switch to check_symbol_exists instead per cmake documentation. Also make sure to link math lib for detection for nix. For MSVC the issue for non x86 builds was that the standard was set to default which is 199409L. This resulted in not using lrintf even that it was found. To address this we set the C standard to C11 and it will only apply to newer versions of MSVC where the /std flag is supported.

| | | | | | | | | | Commit 6577534a80c8 switched from using __get_cpuid() to __get_cpuid_count(), but the corresponding configure check was not updated. Since __get_cpuid_count() was introduced much later, make sure we check for the function we actually use. Thanks to Mark Harris for the report.
