Sarcasm aside...
A good place to start would be
Voicemeeter
Its a virtual audio mixer which allows you to control audio from inputs such as microphone/automation software then you send that audio to a
stand alone encoding program.
As a newbie I'd suggest you do searches on Google, This forum etc... The answers will be out there if only you search for them. You'll find your issue has probably already had an answer.
@neralex Why be unhelpful to a newbie? We all had to start somewhere.
