DTS

DTS is a private company that develops audio formats, similar to Dolby. The term "DTS" generally refers to DTS's digital surround audio technology that is used widely on DVD-Video discs, just like Dolby's Dolby Digital/AC3.

DTS differs from Dolby Digital in that it uses less compression and has a lower bass extension, which allow it to produce a better sound quality.DTS Stereo sounds almost identical to Dolby Surround.
