Some presets for PulseEffects application
If you are struggling to find an equalizer for PulseAudio on KDE 17.10, I really recommend PulseEffects: https://github.com/wwmm/pulseeffects/wiki/Package-Repositories#ubuntu-1710-and-newer
Troubleshooting: If you are getting an error like this "raise ValueError('Namespace %s not available' % namespace)", you need to install gir1.2-gst-plugins-bad-1.0 package.
Just import those presets and enjoy ;)
