Burning Disc-at-Once (DAO or Red Book) CDs

1. Arrange your audio files on the timeline. Use the Track Properties window to change each track's Acid type setting to One-Shot to burn the media to CD using the original project tempo.

   TIP

   If you want to burn a CD using audio from multiple projects, render each project as a 16-bit, 44 kHz wave file and add the rendered wave files to a new project.

2. Position the cursor where you want a CD track to begin and choose CD Track Marker from the Insert menu (or press N) to add a CD track marker at the cursor position. A Red Book CD can contain up to 99 tracks.

   

   When you burn your CD, two seconds of silence will be added before the first CD track. Subsequent tracks will have silence between them only if you use the Insert Time command to add silence before a CD track marker.

NOTE If your first CD track marker is not placed at the beginning of your project, audio that occurs before that marker will not be burned to disc.

TIP CD track markers must be at least 4 seconds apart. Use the Time Ruler to check marker spacing.

Universal Product Codes (UPC) or Media Catalog Numbers (MCN) can be written to a CD as a means of identification. However, not all CD-R drives support this feature. Check your CD-R drive documentation to determine if your drive will write these codes.

Enter the code in the Universal Product Code / Media Catalog Number box on the Summary tab of the Project Properties dialog.

Universal product codes are administered by the Uniform Code Council. For more information, click here.

After arranging your media on the timeline and adding CD track markers, you're ready to burn.

1. From the Tools menu, choose Burn Disc-at-Once Audio CD. The Burn Disc-at-Once Audio CD dialog is displayed.

2. From the Drive drop-down list, choose the CD drive that you want to use to burn your CD.

3. From the Speed drop-down list, choose the speed at which you want to burn. Max will use your drive's fastest possible speed; decrease the setting to prevent the possibility of buffer underruns.

4. Select the Buffer underrun protection check box if your CD recorder supports buffer underrun protection. Buffer underrun protection allows a CD recorder to stop and resume burning.

   Buffer underrun protection can create a disc that can be played in CD players but may contain a bit error where burning stopped and restarted. Consider clearing this check box when creating a premaster disc.

5. Choose a radio button in the Burn mode box:

   Item	Description
   Burn CDs	Begins recording audio to your CD immediately.
   Test first, then burn CDs	Performs a test to determine whether your files can be written to the CD recorder without encountering buffer underruns. No audio is recorded to the CD during the test, and recording begins after the test if it is successful.
   Test only (do not burn CDs)	Performs a test to determine whether your files can be written to the CD recorder without encountering buffer underruns. No audio is recorded to the CD.

6. Select the Render temporary image before burning check box if you want to render your CD project to a temporary file before recording. Prerendering can prevent buffer underruns if you have a complex project that cannot be rendered and burned in real time.

   NOTE The rendered temporary file will remain until you modify your project or exit the application. If an image file exists when you open the Burn Disc-at-Once Audio CD dialog, the check box is displayed as Use existing rendered temporary image.

7. Select the Automatically erase rewritable discs check box if you're burning to rewritable media and want to erase the disc before burning.

8. Select the Eject when done check box if you want to eject the CD automatically when burning has completed.

9. Click OK to start burning.
