(re-posting to the actual mail list)

The simplest way would be to use vstplugin~ and just use a vst plugin you are used to.

Deken should include it. Go "Help" -> "Find Externals" and search for "vstplugin~" (don't forget the "~") Might be not all plugins work as expected (at least on Linux), but I've used it on live stuff and it has worked pretty well for me.

Dear list, I am looking for a simple equalizer abstraction, preferably vanilla, but can be part of an external library, too!

Actually I just need simple low-cutting from low to high frequencies and/or high-cutting from high to low. A visual representation would be great.

Do you know where I can find one?

Thank you,

Jakob

Have you tried [lop~] and [hip~]? [bp~] could also come in handy.

What do you mean by visual representation? Of the input vs. output signal (e.g. a spectrogram)? Or like a UI for the eq? In that case you could connect some [vslider] to the objects above?

Hope this helps, Lorenzo

Those two generate the coefficients that can be fed to [biquad~].

. A visual representation would be great.

The same coeffs that are fed to [biquad~] can be used to plot the frequency response (and phase response) with:

I don't deserve credit for them. They are based on abstractions created by Mike Moser-Booth.

Here is what the filterplot looks like:

Hi,

i recently made a "channel_gui" abstraction for a patch on the RPI, using vanilla filters and the object [equaliser] from the GGEE library (you will need to install that first with deken)

it has a lowpass, a highpass, and one parametric EQ like filter (made with [equaliser], which basically calculates the right coefficients for the vanilla [biquad~] object)

i attach it here, you will have to remove some stuff and tweak it for your needs, but it's not too complicated.

plus you can control output volume and add a delay (if needed)

best
