dts Digital Surround

This offering from Digital Theater Systems is the the high-quality 5.1 channel digital surround sound format based on Dolby Digital. The dts format potentially offers better sound quality because it used less data compression that its Dolby counterpart, meaning that more of the original sound is retained in the recording. The format uses five main speakers, front-left, front-right, front-centre, surround-left and surround-right, plus a dedicated LFE (Low Frequency Effects) channel that feeds an active sub-woofer.
