Advanced Audio Coding
A standardized, lossy compression and encoding scheme for digital audio. AAC is considered the successor to the MP3 format by MP3's creator, Fraunhofer IIS. AAC's most famous usage is as the default audio format of Apple's iPhone, iPod, iTunes, and the format used for all iTunes Store audio (with extensions for proprietary Digital Rights Management (DRM) where used). AAC is also the standard audio format for Sony's PlayStation 3, the MPEG-4 video standard, and several digital radio initiatives.
