AAC and MP3 File Format

iTunes Music Store: Owned by Apple, the iTunes store set the pattern for a la carte music shopping and still reigns king over the customer base. iTunes has sold more than 5 billion songs to date, and it offers excellent integration with the world's best-selling MP3 player, the iPod. It's catalog contains more than 8 million songs as well as a variety of podcasts, TV shows, and movies. The one major bummer is that most of the tracks sold in iTunes can only be played on the iPod or iPhone and not any other MP3 player. You must download the iTunes software in order to access the store, but it works on both Windows and Mac operating systems.

All of the music sold in the iTunes Music Store uses AAC, for playback on desktop or iPod. AAC has also been adopted by the major standards organizations including the ISO MPEG (MPEG-4), 3GPP and 3GPP2, DVB, as well as XM satellite radio. AAC's best known use 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).

Apple Inc. applies FairPlay digital rights management (DRM) technology to regulate protected songs purchased from iTunes Store with iTunes. FairPlay digitally encrypts AAC audio files and prevents users from playing these files on unauthorized computers.

Overall, the AAC format allows developers more flexibility to design codecs than MP3 does, and corrects many of the unfortunate design choices made in the original MPEG 1 audio specification. AAC is a wideband audio coding algorithm that exploits two primary coding strategies to dramatically reduce the amount of data needed to represent high-quality digital audio. 1. Signal components that are perceptually irrelevant are discarded; 2. Redundancies in the coded audio signal are eliminated.
