I'm currently looking to see if Opus could benefit from AVX/AVX2 instructions and I've made some experiments optimizing xcorr_kernel_* function in celt using AVX2 intrinsics and got about 1.5x-1.6x speedup over SSE floating point version in pitch_sse.c. Have AVX optimizations been tried in Opus? Is there someone I could talk to about optimizing compute intensive tasks in Opus using AVX?
