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 allows it to produce a better sound quality. DTS Stereo sounds almost identical to Dolby Surround.

Codec info

DTS Coherent Acoustics is a perceptual audio codec. The main technique used is a QMF filter together with Huffman, ADPCM and vector quantization.

The DTS codec consists of a core and various extensions, that improve quality.
