What is dts

Overview

DTS stands for Digital Theater Systems, a comprehensive audio technology platform that includes surround sound formats, audio codecs, and audio processing systems. Originally developed for cinema applications in the 1990s, DTS technology has become a standard in home theater systems, Blu-ray movies, gaming consoles, and streaming services worldwide. It competes with other major audio standards including Dolby Digital and Dolby Atmos, offering comparable or superior sound quality depending on the specific application and implementation.

History and Development

DTS was founded in 1992 by Didi Duberman and David Ackley when Lucasfilm's sound engineer John Moschitta proposed a digital surround sound system for cinema use. DTS competed against Dolby Digital for cinema adoption, and many major films have been released with DTS soundtracks since the mid-1990s. The technology proved successful in both professional cinema and consumer home theater markets. DTS was later acquired by Xperi (formerly TiVo Corporation) in 2016, which continues to develop and license DTS audio formats globally.

DTS Audio Formats and Specifications

DTS offers multiple audio formats suited for different applications and media. DTS 5.1 is the standard surround sound format with six channels: front left, center, front right, surround left, surround right, and subwoofer. DTS-ES adds a back center channel for true 6.1 surround sound. DTS-HD Master Audio provides lossless (uncompressed) audio for Blu-ray discs, delivering studio-quality sound without compression. DTS:X is the object-based surround format supporting flexible speaker layouts and immersive height channels similar to Dolby Atmos, allowing sounds to be placed as individual objects in three-dimensional space.

Consumer Applications and Device Support

DTS technology appears across numerous consumer devices and media formats. Many Blu-ray movies include DTS soundtracks for optimal audio reproduction. Streaming services including Netflix, Disney+, and Amazon Prime Video support DTS formats on compatible devices. Gaming consoles like PlayStation and Xbox support DTS audio output. Home theater receivers from brands like Denon, Yamaha, and Onkyo typically include DTS decoders as standard features. Soundbars, AV receivers, and home speaker systems often advertise DTS support as a key selling feature for consumers building home theater systems.

DTS vs. Competing Audio Formats

DTS and Dolby audio formats serve similar purposes but use different compression and encoding methods. Dolby Digital is the most widely supported consumer audio format globally, while DTS offers an alternative with its own dedicated following among audiophiles and home theater enthusiasts. Both DTS:X and Dolby Atmos offer immersive, object-based audio with height channels, allowing audio objects to be placed three-dimensionally around a listening room. Both formats are supported on many Blu-ray discs and in select streaming content. The choice between DTS and Dolby often comes down to personal preference, specific content availability, and home theater equipment capabilities.
