How to Convert a CAF File to MP3
Although there are several different ".caf" file formats, there is one specific kind you can convert to other audio files, including MP3. These are known as "Core Audio Files" and are used by the Final Cut Pro, Garage Band and Apple QuickTime (outside of QuickTime, all of the programs only run on Mac systems). Because the .caf files are used in limitation, you may want to convert the files to the more widely accepted MP3 format.
Click the "iMovie" icon on the taskbar at the bottom of the screen.
Click "Window," then choose "Music and Sound Effects" and select the .caf file you want to convert to MP3.
Launch "Garageband (click the icon on the taskbar at the bottom of the screen) and wait for the program to load. Leave iMovie open during this time.
Click-and-drag the .caf file from iMovie into the opened Garageband. Wait for the audio file to convert into the Garageband program.
Click "Share" in Garageband, followed by "Export Song to Disk." Choose "MP3" as the compression format and click "Export." The .caf file is now converted over to the MP3 audio format.
