| 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.

MPEG is a compression standard for processing digital information. Designed for processing and transmission of both video and audio information. In total, there are five varieties, each of which is a refinement of the previous one and is intended for a narrower specification. Widely used by both ordinary users and TV companies. Does not lead to a noticeable deterioration in quality when compressed with the same bitrate. Compression occurs by replacing a sequence of frames with a colour space.
