DSP for Kodi?

I have a RPi3 and I’m in the process of setting it up for the first time. I plan on running LibreElec since I like Kodi and it’s working well on my other Pi.
Is there any addon that will allow me to enter biquad filters? I would like to add a LT… I currently use a standalone DSP but with my new setup I need to do the DSP in the pi.
