real parametric eq?

Or is the main issue that it uses more resources than necessary and can

be

optimised?
      My issue is that it has an awfully bloated filter (which is suboptimal

according to fons) taking up a lot of cpu-power, while for me it could

perfectly to with a parametric eq (either three bands + shelve or four

bands).
    Ok, Thanks for the clarification.  I am pretty sure you know already that

there are two eq modes in jamin? 30 band multi and 3 band parametric with

shelves. However there is not 4 band. It wouldn't be that hard to add

though if you are serious about it as the three band code is a good place

to start.
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,
