AAC and MP3 Files Format

In April 2003, Apple Computer brought mainstream attention to AAC by announcing that its iTunes and iPod products would support songs in MPEG-4 AAC format (via a firmware update for older iPods). Customers could download music in a proprietary Digital Rights Management (DRM)-restricted form of AAC via the iTunes Store or create files without DRM from their own CDs using iTunes. In later years, Apple began offering music videos and movies, which also use AAC for audio encoding.

iTunes supports a "Variable bit rate" (VBR) encoding option which encodes AAC tracks in an "Average bit rate" (ABR) scheme. As of October 2007, Apple has still not added support for HE-AAC which is fully part of the MP4 standard or true VBR encoding to iTunes.Apple's iPhone supports AAC and FairPlay protected AAC files used as the default encoding format in the iTunes store.

Advanced Audio Coding (AAC) is a lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC audio generally achieves better sound quality than MP3 at many bit-rates. AAC audio is best known use is as the default audio format of Apple's iPhone, iPod, iTunes, and the format used for all iTunes Store audio. Sony’s Play Station also adopts AAC audio as its audio and MPEG-4 video standard format.

AAC audio format allows developers more flexibility to design codecs than MP3 does. However in terms of whether AAC audio is better than MP3 audio, the advantages of AAC audio are not entirely decisive, and the MP3 audio specification, while outdated, has proven surprisingly robust in spite of considerable flaws. AAC audio and HE-AAC audio are universally accepted as better than MP3 audio at low bitrates.
