Any idea what the cost of "swizzling" is? I like that term BTW

When I tried SIMD-izing our mix engine, the cost of swizzling for stereo
streams offset the gains of SIMD. In other words if I had to swizzle I was
better off just using plain old FPU code. (Swizzle is Intel's term I heard
at an IDF a few years ago.)

Interleaving is orthogonal to the issue of grouping, or it should be

I agree. But my point was if we stick to mono streams we'll need a away to
represent both cohesively.
