EasyEffects Microphone Preset: Noise Reduction + NPR Masculin Voice

This is a custom input chain for easyeffects for noise reduction and a semi NPR-ish sound optimized for masculine voices with my mic, placement, acoustics, etc. I started with @MateusRodCosta input chain (now deprecated) based on this article from fedora magazine. Soon after I prompted an LLM to produce settings for NPR-like sound. I was skeptic this might create bogus settings, but to my surprise it worked quite well in my subjective testing, so I applied them here. I also added the speech processor effect, and changed the order of the chain based on my subjective testing.

If this config breaks, check my current config file and comment if I need to update the gist.

If you know of ways to improve this configuration, please feel free to comment and make a suggestion.
