This paper presents an overview of the DTS audio coding system. The DTS audio compression algorithm was designed with the primary objective of significantly improving the quality of audio reproduction in the home. Consumers would benefit from more accurate sound recordings that utilised a wider range of audio frequencies, played back through more loudspeakers than in the CD specifications. DTS is intended to be used in a wide range of applications, in both the professional and consumer arenas and that the consumer decoder be computationally simple and yet resistant to obsolescence. This required that the algorithm host a wide range of ancillary features suitable for home and studio use, and operate flexibly within a coding structure based around a complex intelligent encoder and a simple passive decoder.
