Record your own equipment?

My passion is to pick out beats from the internet and write my own texts about them.

now I want to publish them on YouTube or Soundcloud.

But first I have to bring my vocals together with the beat I bought.

however I have no idea how to do that.

I don't know if it is better to go to a recording studio and spend money on the other mixing my voice and the beat together, or if it would be cheaper if I bought a laptop, which I do with it, since I'm more than Want to produce 1 song.

Unfortunately I have no idea how this works, do I need a lot of experience to mix it myself, or is there any software that does this automatically?

I would of course also buy a microphone.

if this is the case with the laptop, I would like to know whether you can take any laptop for it or whether it has to be an expensive one?

Micro and audacity. Watch on Youtube, give enough tutorials.
