Oh wow, sounds like there is a lot I need to learn isnt there, as I said before I am way out of my depth here and really have no idea what I am talking about, but I am willing to learn. And this looks like the place to do such. Exactly what it is I am trying to do is a bit of tweaking I would say, I have several computer software packages such as Cooledit, and Cakewalk and a few free ones I have sourced. I have been given an audio tape by a friend that asked me to burn a cd from it. However the original recording is a bit gggrrr in places, and I thought with these programs I may be able to fix it so to speak. The main tracks are guitar and vocals, it doesnt appear to have any other prominent instruments. He originally recorded the tape using a four track and then mixed it to get the end result, also he sings back up vocals on the whole thing as well, so I pressume these were mixed in at some stage too. Thanks for your help guys, sorry I dont know too much about it all.
