AAC and MP3 File Formats
AAC is the default audio format of Apple's iPhone, iPod and iTunes. Most of the music in iTunes Store is in AAC format. Sony PSP also adopts AAC as its audio standard format. However, AAC is not supported by all media players. If your media player is not compatible with AAC, especially the DRM protected AAC audio, you have to convert the AAC files to MP3 or WMA, or other unprotected audio formats that can playback on your audio player.
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is better than MP3 audio, the advantages of AAC audio are not entirely decisive, and the MP3 audio specification, while outdated, has proven surprisingly robust in spite of considerable flaws.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.
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 file 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.
