AU format for reliable data storage
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.
The format within the MPEG-4 Part 14 standard
Created in 1988, it was intended for video files. A file of this format contains video and audio information, images and subtitles. When compressed, the files do not lose quality. The format includes various types of multimedia content: videos, animations, audio, 2D and 3D graphics. Files of this format can be used and viewed on the Internet. In this case, a metadata transfer takes place. The full name of the format is MPEG-4 Part 14.
