It is employed in satellite broadcasting. The MPEG-1 Audio Layer II format was originally created in the 1990s. The popular mp3 format is one of its components. Its greatest advantage lies in the fact that the files do not lose the high sound quality upon compression. Before the emergence of DVDs, this format was used for compact discs.

AU format for reliable data storage

| Developer | Sun Microsystems |
This audio format was developed by Sun Microsystems. It is intended for storing audio files; the file itself consists of three components: the header, the annotation unit, and the audio file itself. What distinguishes this format is the small file size, due to which its sound quality is low. It can be converted into other formats, such as mp3 or MPEG. Although this format is mostly used on personal computers that are powered by operating systems Sun or Unix, AU files can also be opened using other audio players.
