LV2 Equalization Plugin

EQ10Q is an audio plugin over the LV2 standard (http://lv2plug.in) implementing a powerfull and flexible parametric equalizer, currently in development but fully usable.
The goal is to create an equalizer plugin that includes parametric equalization with diferent filter types like peaking, HPF, LPF, Shelving and Notch with IIR algorithms and a nice GUI displaying the equalization curve.
At the moment we have implemented second order biquadratic filters (Peaking, Low Shelving, High Shelving and Notch), and configurable order (1, 2, 3, 4) HPF and LPF filters. All with IIR algorithms. And a GUI writed with Gtkmm (http://www.gtkmm.org) to control all the parameters and display the curve using plotmm (http://plotmm.sourceforge.net).
The plugin is over LV2 standard and writed in C++ with lv2-C++-tools (http://ll-plugins.nongnu.org/hacking.html) provided by Lars Luthman.

Features
    - 10 Full configurable equalitzation bands
    - 12 Diferents filter types selectable for each band
    - Input and Output level meters
    - Input and Output gain controls
    - Gain, Freq and Q controls for each band
    - Keybord can enter values for each band (double click on the band parameter)
    - A/B Curve comparation
    - Presets
    - Bode graph plot
    - Easy EQ by drag and drop on circles on the Bode graph

Download
At the moment we only have the source code of EQ10Q, coming soon we will have an easy-installation system for EQ10Q.
But you can get the source from sourceforge.net and compile yourself following the README file in the package.

EQ10Q Need Help!
EQ10Q is developed by only one person, for this reason EQ10Q need help from people interested in the project.
If you know C++ and you're interested to contribute you are welcome! Just post in the developers forum (you have to be registred in SourceForge).
You can also be involved reporting about bugs, issues and ideas for new features. Feel free to use SourceForge Tracker for these purpose.
Your help will be so apreciated!

About developer
Pere Ràfols is EQ10Q main developer, he is technical telecomunication engineer specialised in electronics and now he is finishing automatics and industrial electronics engineering (Final Project pending). His experience in the world of audio goes from live music sonorizations to the recording studio.
Pere is very interested in open source and Linux audio software, wich is a viable alternative to audio propietary systems.
