tests/checkasm/lpc: reduce range and use signed values
This is more similar to its regular use, and prevents inaccuracies of huge float*float multiplications from failing the tests. |

tests/checkasm/lpc: randomize buffer length
Simplifies the test, while trying more values and preventing pointlessly running benchmarks in a loop. Signed-off-by: James Almer <jamrial@gmail.com> |

x86/lpc: implement a new Welch windowing function
Old one was written with the assumption only even inputs would be given. This very messy replacement supports even and odd inputs, and supports AVX2 for extra speed. The buffers given are usually quite big (4k samples), so the speedup is worth it. The new SSE version is still faster than the old inline asm version by 33%. Also checkasm is provided to make sure this monstrosity works. This fixes some FATE tests. |
