Yes, most CD burning programs will convert the mp3 files to audio CD format during the burning process. Recommended is burning at minimum speed possible. Use a good brand CD-R (do not use CD-RW), if possible choose a slow speed CD-R (not 40 speed or faster) as many CD players do not like the high speed type disks or a CD-R being burnt at high speeds.

When you burn the CD, choose Audio CD format. There should be such an option in your burner program. Data format disks will not play in CD players.
