AAC Format

AAC with the full name Advanced Audio Coding is the default or standard audio format for iPhone, iPod, iPad, Nintendo DSi, iTunes, DivX Plus Web Player and PlayStation 3.

File Format Description

Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme fordigital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates.

Nowadays AAC is not only acceptable in iPhone, iPod, iPad but also supported on PlayStation Portable, Wii (with the Photo Channel 1.1 update installed for Wii consoles purchased before late 2007), Sony Walkman MP3series and later, mobile phones made by Sony Ericsson; Nokia; Android; and WebOS - based mobile phones. AAC has also seen moderate adoption on in-dash car audio especially on high-end units such as the Pioneer AVIC series.

Cause of Failed Playback

Though Advanced Audio Coding (AAC) is the default encoding used by Apple iTunes and the iTunes Music Store, you might also fail to play AAC files in iTunes if your AAC-encoded audio files were not created with iTunes or donwloaded from the iTunes Store. And since AAC is a container format with different codecs, it might fail to play even on those software and portable players and mobile phones which claims to support AAC playback. If you fail to play AAC audio, optionally, you can convert AAC files to MP3 audio format which is widely supported.
