If I understood Fons and yourself correctly, the "parametric eq" is just another way of modifying the response of the big filter. My idea is _not_ to *add* a three-band parametric, but to *replace* the convolution-based eq with one of the very fine ladspa plugins of parametric eq. This should lower cpu-usage quite a lot. And if your audio signal needs a 31- band or a free-hand-drawn equalizer, you are better off with fixing the mix or using freqtweak, I think. Have fun, Arnold
