Comment 6 for bug 1074346

OK, When I change hue of color, depending of low and high freq. value I got this: http://ompldr.org/vZzQ5cw
Just make this:
- lo = maxLow[0]/300.0;
+ lo = maxLow[0]/200.0;

- color.setHsvF(h, 1.0-hi, 1.0-lo);
+ color.setHsvF(h+(lo-hi)/3.0, s, v);

I think this if worse, than my first screenshot.

About perfomance: my code is use 60% of my CPU when mixxx, but "filtered - software" uses just 40% cpu. Maybe someon can make some optimizations, but I can't...

P.S. I forgot to add one file to my patch, there is:
