"The DTS" is often used as an abbreviation for the Digital Theater System, a multi-channel audio standard used for high-quality cinematic sound. However, there are several synonyms that can be used for this term such as Dolby Digital, THX, and IMAX. Dolby Digital is another audio standard that provides a similar audio experience to the DTS, while THX is a certification process for cinema audio systems that ensures high-quality sound. IMAX, on the other hand, is an immersive cinema experience that includes both high-quality image and audio technology. These synonyms are useful when referring to high-quality cinematic sound, as they all provide a similar experience to the Digital Theater System.
