Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. AAC usually achieves better sound quality than the more popular MP3 format when compared at the same bitrate, especially for bitrates below about 100 kbit/s. It is the default, and most commonly used format for compressing audio CDs for Apple's iPod and iTunes (extension M4A). Apple uses the AAC format for all audio for sale on the iTunes Store and a special proprietary M4P container for Digital Rights Management (DRM) restricted files.
Windows Media Audio (WMA) is brand name for several audio file formats developed by Microsoft. The original WMA, also known as WMA Standard, was initially intended to be a competitor to the popular MP3 format and has become the second most widely supported format for compressed audio. The newer and more advanced WMA Professional has positioned itself as a competitor to the Advanced Audio Coding format (AAC).
