Make a new section with amd relive, named microphone or something, then people are able to add filters such as:
Noise Suppression
Noise Gate
Compressor
Gain
Kinda annoying that it captures my background noise, keyboard and mouse, and also my family pretty good, noise suppression disables that, so background doesn't get picked up, Noise Gate - allows you to set an open and close threshold in dB e.g. my close threshold for my settings on obs is -51 dB and open threshold is -16 dB, when viewing the video/audio back, no background noise is captured when these 2 filters have been applied.
Like OBS Microphone Filters:
