...of encoder performance (on an Athlon XP 1700+) a while back, and found that, for 8kbps CBR complexity 1, I got: (encode/decode speed) basic compile: 29.2x / 168x -O3 -ffast-math -funroll-all-loops -march=pentium3 -fprefetch-loop-arrays -fsingle-precision-constant: 53.4x / 361x With -msse: 65x/386x The actual numbers don't matter much, but it does mean that encoding is almost 6x as expensive as decoding, so expect that you're going to use 60-90% of your CPU for speex encode.. -SteveK -------------- next part -------------- An HTML attachment was scrubbed...
