k how do i
 

cut out a beat from a sample i do with voice in it also like if i recorded pac with a beat in it how can i do that?

you need mixing software with those abilities like Logic Pro or Pro Tools. Or look for the acapella.

Soooooooooo many people ask this same question. People need to start looking to see if a question was already asked to save people time on answering the same question over and over again......:(
