When you rip CDs to create digital music files from the songs on the CD, there are different kinds of digital music files besides MP3. By default, ​iTunes creates files in the AAC format, encoded at 256 Kbps (the higher the Kbps—kilobits per second—the better the sound quality). Even though AAC is the iTunes default, you can change the kind of files that iTunes creates when you rip CDs and add them to your music library.

How to Change the Import Settings in iTunes

Every file type has its own strengths and weaknesses—some have higher-quality sound, and others create smaller files. To take advantage of the different kinds of files, change the iTunes import settings.

  1. Open iTunes and navigate to the Preferences:

    • On a Mac, go to the iTunes menu and choose Preferences.
    • On Windows, go to the Edit menu and choose Preferences.

  2. On the General tab, click Import Settings.

  3. The settings on the next screen control what happens to a CD when you put it into your computer and import songs (or when you use the iTunes built-in music-file conversion feature).

  4. Select the Import Using drop-down menu and choose what kind of audio file is created—MP3, AAC, WAV, or other.

  5. Select the Setting drop-down menu and choose the quality of the files that output. The higher the quality, the better it will sound, but the more space it will take up on your computer or device.

  6. Click OK to save your changes.
