Recording help?

[Say Whaaaaa]

I am going too start a lets play series. (look it up) And i do not wanna record my commentary after i have got done recording the gameplay footage Btw im going too be using dazzle.

So too shorten it up can someone explain how i can record commentary while im recording gameplay footage? Or playing the game.

And i know there's a Google but i think its easier to ask you guys.
