Hi, i see PACK and UNPACK is very fantastic regarding processing. Not just left and right channel processing at one time. I use it in another too, it reduce CPU so much.
my suggestion is, what about if the pack/unpack are not just 4 input/output. Or maybe up to 10 io.
TQ, RP!

The reason there's four is because that's how many SSE channels there are... more than four and you stop getting the benefit.

Wasn't that coming with SSE4?

Are you joking, right? All SSEx are 4 32bit channels, or 2 64bit channels in SSE2+. 8 channel 32bit won't come until next year's CPUs with VEX. SM doesn't even have SSE2 supportyet.

8*16 / 2*64 on xmm1 tm xmm5 would be sweet. Btw.. cant it be possible to get 8*16 with shufps.

Have to use new ymm, not xmm. xmm is only 128bit max.
