You need a good D/A converter; I use an M-Audio Delta 1010. The one in your computer hardly qualifies. You also need decent mastering software. I have used Wavelab (about $500, I guess), which has most of the necessary tools, but is very hard to learn (you probably will want to use some plug-ins, e.g. click and pop filter, equalization, dithering algorithm) and good cd-burning capability. CYou can can burn to 16 bit.wav files or even do higher bit rates if you plan to burn to a dvd or hard drive and play back on a music server. But I agree with Bdgregory above. The amount of work involved in doing it right is enormous. You are likely to quickly realize this and give up on the project. Besides, the records will still sound better.
