The BigScreen Cinema Guide makes a point of highlighting movies showing with digital sound presentations, such as Digital Sound, Digital Sound 7.1 (for 7.1 channel presentations), Dolby Surround 7.1 (the Dolby-branded version), and Dolby Atmos, as well as the film-based formats of DTS Digital, Dolby Digital, and SDDS Sony Digital. These digital sound presentations are indicated by the use of the logos at the right throughout the schedule listings.

Note: As film-based presentations largely have given way to Digital Cinema Projection systems, the SDDS, DTS, and Dolby-branded formats (except for Dolby Surround 7.1 and Dolby Atmos) will disappear with them. When a theater does provide a film-based presentation with a digital sound format, we will provide that information when it is provided to us.

What About THX?

THX is not a digital sound format, but rather a certification for movie theaters that dictates the quality of the construction, the components used, and a calibration of the sound system that is repeated on a yearly basis. THX makes digital sound better!
