hi friend
first of all try to get a good microphine. u can use software ranging from soundforge, cooledit,... to our windows sound recorder.
u can also use creative's wave studio, which i've found a very good one. if u own a creative soundcard u can find it in the installation cd. or borrow it from some of ur friends as it is easy to get
hope u create good commentaries soon
thanx
