Is there an equalizer in the BASE (that is not PPA) Ubuntu 14.04?
(I have PulseAudio)
There are 2 in the repositories for specific soune systems:
Alsa:
sudo apt-get install libasound2-plugin-equal
LV2:
sudo apt-get install eq10q
For pulse you are bound to be needing a PPA. Link to some PPA's (in case you change your mind ;) ):
