Audio File Formats Supported by iPod
• AAC (M4A, M4B, M4P) (up to 320 Kbps)
• Apple Lossless (a high-quality compressed format)
• MP3 (up to 320 Kbps)
• MP3 Variable Bit Rate (VBR)
• WAV
• AA (audible.com spoken word, formats 2, 3, and 4)
• AIFF
A song encoded using Apple Lossless format has full CD-quality sound, but takes
up only about half the amount of space as a song encoded using AIFF or WAV
format. The same song encoded in AAC or MP3 format takes up even less space.
When you import music from a CD using iTunes, it is converted to AAC format by
default.
You can convert nonprotected WMA files to AAC or MP3 format. This can be
useful if you have a library of music encoded in WMA format. For more
information, open iTunes and choose Help > iTunes and Music Store Help.
iPod does not support WMA, MPEG Layer 1, MPEG Layer 2 audio files, or
audible.com format 1.
