Recently googled some pic about good EQ setting to be implemented on Audacious (the 4th audio player i’ve tried), then google referred to this link, download the EQ plugin package, make /rhythmbox/plugins/ directory in my ~/.gnome2. Unpack with “tar -xzvf rhythmbox-eq.tar .gz -C ~/.gnome2/rhythmbox/plugins/“.
Now my Rhythmbox has an equalizer, horaaaayyyy😆. It is located in Edit->Plugins->Equalizer->Configure. Thanks to Teemu Kallio for this awesome plugins.
PS: Jorge said that he revisited his post about this plugins, but then, I’m doing fine with this version😉
