AAC and MP3 Files Format

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is better than MP3 audio, the advantages of AAC audio are not entirely decisive, and the MP3 audio specification, while outdated, has proven surprisingly robust in spite of considerable flaws.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.

While Apple is normally terse in describing its software updates, the new version of iTunes is the shortest in a while. According to the notes provided by the company, iTunes 7.7.1 “includes fixes to improve stability and performance.”

An article on TidBITS this morning quotes an Apple employee that posted to the company's forums last night explaining several of the fixes in the update. Apparently at least five items have been fixed including corruption of accented artist names, a bug that prevented CDs from being ejected, iPods not being recognized, long iPhone backups and a sync issue with Outlook.

iTunes was last updated the day before the launch of the iPhone. That update brought support for the iPhone 3G and the App Store. The release also supported Apple Remote, a new application that allows users to connect to their iTunes library or Apple TV from the iPhone or iPod touch.

iTunes: 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.
