Because your computer is in the digital world, anything seen or heard on your computer is already digital. All your files saved on your computer ARE digital. You may want to change the format. I suggest you research before jumping in. The most common formats are FLAC and APE lossless and mp3 lossy. You can not hear the difference between lossless and HiFi lossy but you lose a great deal of quality going to lossy. A good way to preserve your work is to burn your lossless album to CD then convert the lossless to a HiFi mp3 using a HiFi encoder like Lame. Then you do not really need the lossless files. Some keep the lossless files to be more safe.
