FxSound has been pretty cool for being an intermediate EQ that helped me clean up the muddy sound the bluetooth speaker I have produces. It isn't as powerful as VoiceMeeter but for me its is using a lot less CPU. It has too many presets though, I only want one preset per device I actually listen through. 

Navigate to this directory: C:\Program Files\FxSound LLC\FxSound\Factsoft. Then move out or delete all the *.fac files except for Default. Presently it seems to ship with files 1.fac to 12.fac. After relaunching the app without the excess fac files the preset menu will be nice and clean.
