An Advanced Audio Coding file, known as AAC, uses compression much like that of an MP3, according to FileInfo. AAC serves as the default audio format in iTunes, but can also be opened in other media players, such as RealPlayer and Media Player Classic. If you would like to burn an AAC file to an audio CD, you do not need to convert the file. A few programs can burn AAC files to disc.
Download the iTunes software from the Apple website if it is not already installed on your system. Versions of iTunes exist for both Mac and Windows computers. Once you download the file, install the program to your computer by double-clicking the download icon and following the screens.
Put a CD-R into the CD drive of your computer and open iTunes. On a Mac system, the iTunes icon appears in the docking bar and can be clicked once to open the program. In Windows, open iTunes from "Start>All Programs."
Open the "Edit" menu and click "Preferences." In the "Preferences" box, switch to the "Burning" tab and choose "Data CD" from the list of "Disc formats." The data CD option is the only burning option that can burn AAC files to disc.
Create a playlist in iTunes that contains the AAC file you want to burn to CD. To create a playlist, go to "File>New Playlist," type a name for the playlist when prompted. Then, return to "File" and choose "Add File to Library," find the AAC file on the hard drive and double-click it to add it to iTunes. Once the file appears in the iTunes library in the right-hand pane, drag the file to the playlist icon in the left pane.
Click the "Burn" button that appears in the right corner. The AAC playlist burns to the CD in the drive.
Download Music Man from the Mireth website (see Resources.) According to the Mireth page, Music Man is only compatible with Mac systems. Install Music Man to your system.
Place a CD in the CD drive and launch Music Man. To open Music Man on your Mac, go to the "Finder," click "Application," scroll to the "Mireth" folder in the application list, click the folder and click "Music Man."
Click the tab labeled "Music" to show the CD-building tools. Click the "+" and navigate to the folder that contains the AAC file in the window that comes up. Click "Add" to add it to the Music Man library.
Use the "+" button that appears under the "Playlists" heading to create a new playlist. Then, click the "Library" heading and navigate through the music files stored in Music Man. When you find the AAC file, drag it to the playlist folder you created.
Click the arrow next to the "Burn" button to select the "Burn Music CD/DVD" option. Then, click the "Burn" button to burn the AAC playlist to the disc.
Download Nero Burning ROM from the Nero website, and an AAC/MP4 plugin for the program (see Resources.) Install Nero Burning ROM to your system first by double-clicking the program icon and following the on-screen instructions. Then, install the plugin by right-clicking the download icon and choosing "Extract All." Nero Burning ROM and the AAC/MP4 plugin work on both Mac and Windows computers.
Place the CD into your computer's CD drive and open Nero Burning ROM. On a Mac, go to "Finder>Applications," and on a Windows system, go to "Start>All Programs" to locate the program.
Go to the "Audio" tab and pull down the menu in the top left corner of Nero Burning ROM to select "CD." Then, click "Audio CD" in the left pane to bring up a new Audio CD project.
Navigate to the folder that contains the AAC file you want to burn in the right pane. When you find the AAC file, drag the file from the right pane to the left pane to add it to the burn list.
Go to the "Recorder" menu and click "Burn Compilation." Click the "Burn" button to burn the AAC file in the burn list to the CD.
If “Extract All” does not appear as an option when you right-click the Nero plugin, it means you do not have an unzipping program installed. You can install either WinZIP or WinRAR for free.
