Using module-ladspa-sink - what LADSPA plugin exactly do I need to install?

[Doron Behar]

I found this program I'd like to use:

https://github.com/pulseaudio-equalizer-ladspa/equalizer

I managed to compile and run it, but I don't hear it makes a difference
in the sound. Do I need to enable the `module-ladspa-sink` module? Link:

https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/#module-ladspa-sink

What makes it difficult for me to figure this out myself, is the
[LADSPA](http://www.ladspa.org/) link, which seems to general, because
this group develop many projects, or which I'm not sure which I should
compile as a pulseaudio plugin (some of which are available in my
distribution.

Thanks for any help in advance.
