Music files in iTunes have different extensions according to the format. If the format is not compatible with the player, then the music file may not be playable on the device. Therefore, it is necessary to understand the music file extension in iTunes.

Apart from this, we will also teach you an easy way to convert iTunes music to MP3 files, so that you can enjoy iTunes music on any device, tablet and player without restrictions.

Part 1. Differences in iTunes Music File Extensions

Currently, iTunes works with five audio file formats, including MP3, AAC, AIFF, Apple Lossless, and WAV.

MP3 (MPEG audio file) is the most popular type of lossy compressed audio format. Compared with other uncompressed audio formats, MP3 takes up less space on the device. It is supported by almost all devices, tablets and players.

AAC (Advanced Audio Coding) is a standard audio file developed by Apple. It is lossy and compressed, an Apple’s alternative to MP3. The AAC audio format can be divided into protected AAC (.m4a) audio files and unprotected AAC (.m4p) audio files.

Protected AAC (.m4p) audio files: Some songs purchased from the iTunes store and subscribed Apple Music songs are in the protected AAC format, also known as M4P files. This DRM restriction prevents songs from being copied or shared.

Unprotected AAC (.m4a) audio files: After April 2009, all songs sold in the iTunes store are in the AAC audio file format without DRM protection.

AIFF file is an audio file saved in the Audio Interchange File Format. It sounds better than MP3, as it is lossless and uncompressed (so big file sizes). AIFF is the standard audio format for Mac, Apple’s alternative to WAV.

WAV, is known for Waveform Audio File Format. Similar to AIFF, WAV is a lossless and uncompressed audio format, which is a standard audio format for Windows. And the size of WAV files is bigger than MP3, M4A, almost all CDs are encoded in this format.

Apple Lossless is a lossless format that retains the full quality of uncompressed audio, but takes up much less space; usually about 40% to 60% less than WAV or AIFF files.
