Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. AAC usually achieves better sound quality than the more popular MP3 format when compared at the same bitrate, especially for bitrates below about 100 kbit/s. It is the default, and most commonly used format for compressing audio CDs for Apple's iPod and iTunes (extension .M4A). Apple uses the AAC format for all audio for sale on the iTunes Store and a special proprietary .M4P container for Digital Rights Management (DRM) restricted files.
