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.
MPEG-4 Part 14 is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still drm-remover. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. The official filename extension for MPEG-4 Part 14 files is .MP4, thus the container format is often referred to simply as MP4. Devices that play MP4 files are referred to as MP4 players.
