This is a simple gnome extension which adds a "equalizer" menu voice in the status panel of the top bar under the volume controller. The "eqaulizer"" voice has a sub menu, whose first voice is "qpaeq". When clicked it opens the qpaeq equalizer application.
Use git:
git clone [email protected]:kgaut/gnome-shell-qpaeq-launcher.git ~/.local/share/gnome-shell/extensions/gnome-shell-qpaeq-launcher@abidibo
Then restart the gnome-shell via alt+F2 r and enable the extension using gnome-tweak-tool, or use gsettings command line tool.
To update later, just issue
(cd ~/.local/share/gnome-shell/extensions/gnome-shell-qpaeq.launcher@abidibo && git pull)
