AAC - Advanced Audio Codec

The AAC features in both the MPEG-2 and MPEG-4 standards and was designed to be the successor to MP3. As such, AAC can operate using a variety of bitrates whilst sustaining adequate sound quality. AAC has been adopted for use in a wide variety of devices, ranging from Apple’s iPod to the Nintendo Wii. A low bitrate variant of the AAC, termed the HE-AAC (High Efficiency Advanced Audio Codec) is also available.
