Developed and introduced in 2005, the Digital Theater System format is used in HD films. DTS has a multi-channel sound with various functions. All audio information is divided into five tracks. A separate audio player is not required. The Digital Theater System format allows you to achieve the five-channel sound that is used in cinemas. The rate of the digital stream amounts to 1,536,000 bits per second. DTS is compatible with the 7.1 acoustics format and the conventional stereo format.

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.
