Using VST Plug-ins in OBS is a great way to gate, compress, eq and de-ess your audio for streaming on Behance. There are many free or low cost VSTs out there to choose from, great sales that happen, and certainly you do not need to use the one I chose as it's merely an example. Good luck with your streaming on Behance!
