Make a new section with amd relive, named microphone or something, then people are able to add filters such as:
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:
relive does need to improve mics.. but rather than implementing some filters of their own, it might be better for them to just have the ability to use VST plugins.. install the reaper plugins and you have better mic filtering than anything they could provide on their own
