Function [up] [down]
Works on high frequencies, means supresses or boosts them while leting low frequencies pass through unaltered.

Parameter [up] [down]
Effect (P1)how much the operator effects the outcome. Negative values produce theopposite effect - they boost frequencys.
Cut-Off (P2)Area for averaging-calculations. The wider that range, the higher thecut-off frequency gets.
Resonance (P3)Strength of resonance (also Peak or Q-Factor).As a strong resonance thins out the signal, there is an amplification-factorthat runs parallel with the resonance, thus gets modulated too. A resonanceof 0.0 should have an Amp=100 %. Higher resonances should get higheramplify values. You'll have to experiment to find the perfect values (try resonance+100 %).

Notes [up] [down]
These filters are based on a very simple model and are therefore not very precise, but quite fast to calculate.
And be careful. If you just hear a loud metallic noise, then you've turned resonance up too far.
