DTS

DTS, short for Digital Theater Systems, is a family of multichannel audio codecs and related technologies developed for cinema and consumer electronics. The original DTS Digital Surround format, introduced in the 1990s, delivered discrete 5.1-channel sound at higher bitrates than some competitors and helped popularize digital surround sound on home video.

The DTS codec family has expanded to include several formats:

- DTS Digital Surround, the original 5.1-channel format used on many DVDs.

- DTS-ES, Extended Surround, introducing either matrix-encoded 6.1 or discrete 6.1 channels.

- DTS 96/24, a high-resolution variant supporting 96 kHz sampling on selected titles.

- DTS-HD, a set of Blu-ray and HD-DVD compatible formats, including DTS-HD Master Audio (lossless, up to 7.1 channels, with a core DTS Digital Surround bitstream for compatibility) and DTS-HD High Resolution Audio (lossy but high fidelity).

- DTS:X, an object-based audio format announced in 2015 to enable flexible 3D sound positioning, similar in concept to Dolby Atmos.

- DTS Neural:X, a upmixing technology designed to derive multichannel sound from stereo or lower-channel content.

Applications and reception: DTS technologies are used on many Blu-ray discs, some DVDs, streaming services, and in home theater systems. They are designed to deliver high-fidelity sound and flexible speaker configurations and continue to coexist with competing formats such as Dolby Digital and Dolby Atmos.
