Dolby Digital Plus: Consistent Quality on Every Device
Enjoy vibrant, high-quality surround sound from all your favorite content with Dolby Digital Plus™. Whether you're watching movies, TV shows, online videos, or concerts, Dolby Digital Plus ensures that you always get consistent audio quality.
The Technology
Dolby Digital Plus is an audio technology based on Dolby Digital 5.1, the established standard for cinema, broadcast, and home theater surround sound. It's part of a complete ecosystem that includes content creation, program distribution, device manufacture, and customer experience.
How It Works
Based on both psychoacoustic and cognitive models of audio perception, Dolby Digital Plus delivers HD-quality audio for streaming, on-demand, and downloaded content by using some of our most advanced algorithms. Dolby Digital Plus makes it possible to store and transmit high-quality digital sound to deliver the best audio quality possible on many different kinds of devices.
Compatibility with Current Equipment
Equipment with Dolby Digital Plus will unlock its full feature set, including 5.1- and 7.1-channel capability (depending on the program).
If your system includes only Dolby Digital, you'll still get 5.1-channel surround sound, with the highest-quality Dolby Digital signal possible—Dolby Digital Plus content is easily converted to a traditional Dolby Digital signal.
Dolby Digital Plus Products and Content
You can get the Dolby Digital Plus experience by purchasing home theater equipment, such as A/V receivers, Blu-ray™ players, or TVs with Dolby Digital Plus. It's available on PCs, tablets like the Amazon Fire, and on smartphones. Dolby Digital Plus is also a core format for Dolby Audio, built into Windows 10 and the new Microsoft Edge browser, available on PCs and the Surface™ tablet.
Look for content encoded with Dolby Digital Plus on Blu-ray Disc and on streaming platforms such as Netflix, Vudu, or Amazon Fire TV.
