The compression gap widens when you step up to the competing HD formats. For DVD discs, it supports up to 768 kbits/s. For DVD discs, it supports a slightly lower bit rate: up to 448 kbits/s.ĭTS on the other hand, is less compressed and supports higher bit rates of up to 1.5Mb/s (megabits per second). Dolby Digital compresses 5.1 digital audio down to a bit rate of 640 kbits/s (kilobits per second) for Blu-ray discs. The major differences are the compression levels and bit rates.

In 1996, DTS began cropping up in consumer hardware. The company got its big break when Steven Spielberg chose DTS for his dino-romp, Jurassic Park. There's also the next-gen, object-based audio system, Dolby Atmos.ĭTS (originally Digital Theater Systems) was founded in 1993 to compete with Dolby Labs for surround sound supremacy.
DTS VS DOLBY DIGITAL MOVIE
Want the best? Try Dolby TrueHD, a lossless format that promises to be identical to the movie studio's master recording. Since then, Dolby has released a slew of increasingly advanced codecs including Dolby Digital Plus, which supports HD surround sound and up to 7.1 speaker channels. The first film to use Dolby Digital was Batman Returns in 1992. It delivers a cinematic surround sound experience and is commonly referred to as the 'industry standard' (primarily because Dolby Labs has been around longer than DTS).

More advanced versions of these formats can support 7.1-channels, HD surround sound, extra subwoofers and even separate overhead speakers, in the form of DTS:X and Dolby Atmos.ĭolby Digital is a multi-channel audio codec by Dolby Labs.

In their most basic form, both DTS and Dolby Digital support 5.1-channel audio (in a home cinema this is the front left, centre, right, surround left and surround right and discrete subwoofer channel (that’s the. As a consumer it can be confusing to see these different formats and the many offshoots of the technologies but you don’t generally have to choose one.
