MP3 files are a file format meant for audio storage. While they are generally smaller than WAV files, which also are meant to store audio, they can still be too big to meet a certain size requirement.
Step 1
If you wish to create smaller MP3s when importing files from a CD, navigate to "iTunes," then "Preferences." Choose the "Import Settings" tab.
Step 2
Choose "Custom" as the setting, and "MP3 Encoder" as what to use to import. This should make the MP3 encoder window come up.
Step 3
Choose "Use Variable Bit Rate Encoding (VBR)," and choose "Medium" or lower.
Step 4
Lower the sample rate, or switch it to "Auto" on its drop-down menu.
Step 5
Change the channel from "Stereo" to "Mono." This will decrease the file size, but also cause your audio to sound more flat. Use it just as a means to drop down your file size.
Step 6
Select "OK," and import your music.
