    2. You'll be burning the protected files to audio CDs and then ripping them back to the computer to strip them of DRM. This will result in a slight loss of audio quality. You'll need a drive capable of burning CDs (most modern computers have one).

You can download Adapter from macroplant.com/adapter/. You can use adapter to convert WMA files to M4A or MP3 (as well as a variety of other formats).
