Replying to If you really understand audio please help me +k

So i have been editing and filmig for a while now and i understand that. But i do not know a single thing about audio. I want to buy a mic in the future, but i would not understand any of the tech specs, so i would not know what to go off of when i bought one. Can someone just explain what the tech specs are when it comes to audio, what i should look for, and just all around anything having to do with audio i would really appreciate it.

Thanks, +k for help.

and yes i googled most things, but i still am confused by the answers i get.
