AAC (Advanced Audio Coding) is a file format for storing digital audio. It’s commonly used for storing music on the Internet, PCs and portable music players and phones.
It is similar to MP3, but it was designed to be its successor and offers better quality and smaller file sizes. It also supports DRM, which enforces copyright.
AAC+ and AAC++ are newer versions of the standard.
