* lavc/lpc: exploit even symmetry of window functionGanesh Ajjanagadde2016-03-101-1/+2
| | | | | | | | | | | | | Yields 2x improvement in function performance, and boosts aac encoding speed by ~ 4% overall. Sample benchmark (Haswell+GCC under -march=native): after: ffmpeg -i sin.flac -acodec aac -y sin_new.aac 5.22s user 0.03s system 105% cpu 4.970 total before: ffmpeg -i sin.flac -acodec aac -y sin_new.aac 5.40s user 0.05s system 105% cpu 5.162 total Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanag@gmail.com>

* lpc: add ff_lpc_calc_ref_coefs_f() functionRostislav Pehlivanov2015-09-011-0/+20
| | | | | | | | | | | This commit adds a function to get the reflection coefficients on floating point samples. It's functionally identical to ff_lpc_calc_ref_coefs() except it works on float samples and will return the global prediction gain. The Welch window implementation which is more optimized works only on int32_t samples so a slower generic expression was used. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* lpc: create a simplified Levinson-Durbin LPC handling float samplesRostislav Pehlivanov2015-08-291-0/+56
| | | | | | | | | | | | | | | | This commit simply duplicates the functionality of ff_lpc_calc_coefs() for the case of a Levinson-Durbin LPC with the only difference being that floating point samples are accepted and the resulting coefficients are raw and unquantized. The motivation behind doing this is the fact that the AAC encoder requires LPC in TNS and LTP and converting non-normalized floating point coefficients to int32_t using SWR and again back for the LPC coefficients was very impractical. The current LPC interfaces were designed for int32_t in mind possibly because FLAC and ALAC use this type for most internal operations. The mathematics in case of floats remains of course identical.
