i've been looking all over for the last few days, and i've been unable to come up with how they work\integrate into a typical media player

i'm somewhat familiar with the DSP in the kx drivers ( pic here http://djdecks.be/images/kxDSP_Audigy2.gif )

i was wondering if it works similar to this?

i'm looking at building a carputer and these features are fairly critical to choosing between a pc and laptop, with kx drivers i can do the time alignment and crossover\eq'ing in the dsp, i'm hope to see how i can do this without using a old audigy card.
