i love seeing tips like these on my fyp

For voicemeeter users. You can use a VST host for your plugins(filters). 
Benefits of this is that your plugins will also work on other applications like Discord, in-game voicechats, zoom, teamspeak, skype, etc. 
*CAUTION* using heavy plugins like de-reverb or some noise-suppressions will cause noticeable latency; but this applies to OBS filters too..

Below is a super duper scuffed, long-winded, hard to read guide LOL
Also this is assuming you already know how to use/setup voicemeeter as your mixer. 

I use LightHost and it's working pretty seamlessly for me. 

1. Download your plugins and LightHost (lots of free stuff like reaper plugins)
2. Voicemeeter System settings>check the little boxes for the input(s) you want the plugins to apply to
3. LightHost sits in your system tray. Left click it and select preferences. Choose your audio type, Device, and make sure sample rate matches your systems settings. 
4. Left click LightHost from system tray again and select  Edit Plugins. This is where you select the plugins you want to use (Do not scan everything or it will crash, you need to know where they're installed and which ones you want to actually use)
5. A small i> looking icon should appear below your Voicemeeter input and click that to enable.

Remember that plugin order does matter i think :)
