Linkwitzriley 8 EQ Effect

This one should sound better at the crossover frequencies compared to the butterwoth 8. 
It has a constant phase shift = a non const, but linear goup delay.
It comes with a small amount of more CPU compared to butterworth 8 
Gain ramping is not yet implemented.

IMHO it is a candidate to entirely replace the butterworth.


No, because we do not own the effect parameters m_pPotLow ..
