Most cd players can't handle mp3s, though that's changing, so your audio files need to be .wavs. Programs like Nero will convert to wav from mp3 if you tell them that you want to create an audio cd but it's better to start from a wav if at all possible. Every time you do a format conversion you're likely to degrade the audio quality, so you should do as few as possible. Also, mp3s are a lower quality, though you may not be able to notice the difference, depending on the quality of the audio equipment and how good a listener you are. Stick with .wavs as much as possible - you use more disk space but the quality's better.

When you come to burn your cd make sure "Disk at once" is selected in your burning program - the disk wont play if you don't! You may also have some compatibility issues, particularly with CD-RW. If you're up against deadlines it might be a good idea to check in advance.
