Recording

First I want to give all of you DJ's my respect because you all truly make this world go round. Always an avid music lover and always admired all the mixes I heard all my life so I am now into it and I mix salsa music and classic house music. I have an amazing library of that music and I am getting real good at mixing the music and I am getting gigs and all I use is my PC and a large Amplifier with an AUX cable and my question is how can I record my mixes on this application. Currently I have the free version but want to know what to purchase in order to record my mixes to drop on a cd..
