Pull requests are welcome. Please verify that all optimizations have the intended performance enhancing effects on various platforms before filing, though.
For instance, the conversion to integer fixed point is currently used only for the per-sample volume ramping, and may actually be slower on some systems. It was actually faster on the system I developed it on originally, an Athlon64 3200+. Perhaps all float is faster now?

Thanks. I'll do some profiling to check if my modifications are worth. Floats are nearly as fast as ints, but with CPU pipelines you can sometimes perform some operations for free while you are doing other things, so actually it's possible that mixing types makes the algorithm faster

Incidentally, samples are only float because of the newer resampler. I could probably turn that mess into integer as well, since pure integer math is actually faster. Well, unless you or someone else wants to craft fully SIMD optimized mixing code. What happened with this, anyway?
