Hi Gary,
Thanks for responding - but yeah I think you misunderstood me. I'm
trying to wrap Apple's EQ AUs in to a nice EQ effect for a mixer
channel. So I don't have access to the methods they're using to
calculate the curve, just the parameter values. (I should have
mentioned that in the first email :-))
But I know that when using a parametric EQ it's very useful to get a
visual of the curve. So...
Thanks,
Robert.

I've checked musicdsp.org but only found a detailed paper on
parametric
EQing in general. Should I use the equations in that paper or is there
something simpler than can be a good approximation for display
purposes?
Er, I'm confused, the answer here seems obvious (to me) so I'm
hesitant to
suggest it, I fear I'm missing the gist of your question.
But here goes:
If you need to represent an EQ curve graphically, my suggestion would
be to
take a look at how this is done in current audio apps/plugs.
Digital Performer, Cubase, Logic etc. all have built-in plugs that
provide
parametric EQ. Looking at their interface will be enlightening.
If you don't have access to those apps, you might visit the product
home
pages for each, there are usually screen shots of the program some of
which
might include screen shots of the EQ plug.
In addition to the stock plugs for the various audio apps, there are
third-part plugs that also do EQ. You might look for screen shots on
the
Waves site and Metric Halo site among others.
If worse comes to worst, I can take some screen shots (of the DP
parametric
EQ plug-in) and email them to you.
Or did I completely miss what you were asking?
