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.
Now I am not sure that the 3 band parametric should be considered a *real*
parametric or not. However I have been told that the implementation of the
linear filter in jamin is fundamentally correct as the FFT/IFFT approach
is the preferred implementation to obtain a more idealized functionality
of those forms of EQ without screwing up the phase.
Fons has cause for suspicion about the current optimisation. It may turn
out that it is possible that we could shave off some cpu cycles. Perhaps
we can get to the bottom of that problem, but as we are using these large
windows to increase the smoothing across the bands(?) it may be that there
is no further optimisations that can be achieved.

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).

There is one exception to this rule:
When you have a stereo feed from the console and a stereo feed from
room
mics,
you can't get back to "mixing" to fix the issues that you can easily
fix
with
multi-band compression.
If jamin's eq was replaced with a real parametric eq, that would be
cool.
It
would fix a lot of issues raised and lower the cpu-usage. *dreaming*
Just for the sake of clarity, now the problem is that jamin doesn't have
a
real parametric eq?
Or is the main issue that it uses more resources than necessary and can
be
optimised?
