Question: How do I make an audio CD with audio files downloaded to my computer? —B.K.

Answer: These days the most common format for music files on the web is MP3. So here are step-by-step instructions on how to create an audio CD from MP3 files.

This disk should play on most CD players in home stereos, computer CD and DVD drives as well as portable CD players.

The first thing you're going to need is CD creation software. You want to burn the files onto a blank CD.

The term burn refers to the process of permanently transferring files onto CD using special burner software and a CD-R or CD-RW drive. Those drives use a laser to change the surface of a a blank CD and in doing so store data to it.

For purposes of this column, we're going to take you through a burning process using Nero Burning ROM, a CD burner utility from Ahead Software. ( You can get the demo version from the Nero site (5.5 or newer) and install it. It's free for 30 days.

Nero is an excellent program for this purpose for several reasons;

  1. It can automatically convert MP3 files into standard CD audio files while burning. No need to convert the files first.
  2. It has a very easy to use interface with a simple drag and drop approach to CD creation.
  3. The software is very dependable, supports a wide array of hardware and has a low incidence of errors which would result in the creation of dud disks (commonly referred to as "coasters").

So let's begin. Your first step is to get a copy of the software (from the links mentioned above) and install it.

Once installed, you're ready to try creating your first audio CD. One of the helpful things about Nero is the "Wizard". As seen below the wizard will ask you questions about the type of CD you wish to create.

Follow the wizard's questions and choose to "compile a new CD" then "Audio CD" then "Finish".

As the wizard points out, it is unwise to use rewriteable CD-RWs disks to create audio CDs, stick with blank CD-R disks. CD-R disks can be burned once. Once the data is on them, it cannot be removed. CD-RW disks can be burned, then erased, then burned again many many times.

Now we find ourselves at the main Nero window. Notice how the program is divided into a left window and a middle and right window with a task bar above and an index below.

On the right side of the center of the window see a file browser made up of two windows (middle window and right-hand window). They operate much like Windows Explorer showing folders and files on your hard drive.

Your hard drives and folders are viewed on in the middle pane and file content is on the right. In the middle pane, select the hard drive in which you have stored your MP3 files and then find the folder that contains the songs you wish to burn onto CD. Now drag them from the right pane into the left hand panel which is titled "Audio 1".

As each file is added to the list two things will happen. First Nero will check each file to ensure it isn't damaged or corrupted. A corrupted file could result in an error during burning that would ruin the CD and prevent it from being playable.

If Nero warns you that a file is corrupted, don't use it for your CD. If you do want to include that song, obtain a different copy.

Second, you'll notice the bar at the bottom begins to increase as each file is added. This bar measures the estimated length of each file and the relative room it will take up on the final CD.

Notice the yellow and red dotted lines at the end of the bar. These indicate the "caution zone" for most conventional CDs. If you try to stuff too many songs onto the CD, the bar will turn yellow and then red, indicating that Nero could, and probably will, fail in creating the finished CD as the data size exceeds the capacity of the disk.

Note that you'll get about 70 minutes of audio on the CD. Of course, the lengths of songs vary, but assuming each is about four minutes, you'll get about 16 or 17 tracks on your audio CD.

Try to keep the bar blue and to the left of the yellow line.
