Crackling in mic- free decrackle plugin please

[MJ Powers]

For some reason my mic started crackling out of no where. It didn't crackle before. I'm using a fifine mic that plugs straight into my laptop and there are crackles every time I record now. Do you think it's a problem with the wires because I googled it and that was an option. Also does anyone know of a FREE decrackle plugin. Right now I'm not in a place to spend money but I could really use any half decent free plugin because the crackles only appear every once in a while- it doesn't happen every single time I sing.

Toss that POS in the garbage and by a proper Mike and Audio interface. Those are for Podcasting not serious audio recording. The software is free but building a properly functioning recording system is not.

What mic and audio interface would you recommend. I can't spend more than like 200 dollars  and I want something with decent quality

Are you in the States?  Go on the Sweetwater sight.  That gives you a good idea of pricing. 
I would think you could get a Focusrite Solo and a Mike and cable for that price. They sometimes have packaged deals were you get everything
