Auro 3D
Auro-3D is an immersive 3D audio format. It is designed along three layers of sound (surround, height and overhead ceiling), building on the single horizontal layer used in the 5.1 sound format. Auro-3D creates a spatial sound field by adding a height layer around the audience on top of the traditional 2D surround sound system. This additional layer reveals both localized sounds and height reflections complementing the sounds that exist in the lower surround layer. The height information that is captured during recording is mixed into a standard 5.1 surround PCM carrier, and during playback the Auro-3D decoder extracts the originally recorded height channels from this stream.


Dolby Atmos
With Dolby Atmos, sound comes alive from all directions, including overhead. The format combines a channel-based audio bed with object-oriented sound to place and move specific effects around the theater, creating a breathtakingly realistic and captivating sonic atmosphere. Sound designers and artists are free to mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels. In commercial theaters, it supports up to 128 audio tracks and 64 unique speaker feeds. The home theater adaptation automatically scales to your surround configuration.

Dolby TrueHD
Dolby TrueHD is Dolby’s latest lossless technology, the ultimate audio experience for high-definition disc-based media. Dolby TrueHD on Blu-ray Disc allows viewers to hear exactly what was captured during the recording and mastering process, bringing a palpable and involving audio presence to the home theater experience.

Dolby Digital Plus
Dolby Digital Plus is the next-generation audio format that delivers “better-than-DVD” sound in high-definition packaged media because it requires less compression and provides more channels (up to 7.1). Dolby Digital Plus also provides new coding efficiencies for future broadcasting and streaming of multichannel audio.

Dolby Digital EX
Dolby Digital EX introduces a center rear channel to 5.1-channel playback, expanding the surround sound experience to 6.1 channels. It intelligently identifies audio information in the left and right surround channels. One or two speakers placed behind the listener provide increased realism for front-to-back sounds and those originating from directly behind the listener.

Dolby Digital
Dolby Digital is a powerful audio format that provides up to 5.1 separate channels of crystal-clear digital surround sound, bringing entertainment to life. A worldwide standard in film, broadcast, and DVDs, Dolby Digital delivers unrivaled audio in a home theater subwoofer for an exciting, enveloping surround sound experience.

Users can enjoy PC or game audio entertainment with exciting realism through home theater receivers or other devices equipped with Dolby Digital decoding technology.

Dolby Surround
Dolby Surround technology encodes four channels of audio (Left/Center/Right/Mono Surround) onto just two audio tracks for media such as TV broadcasts and feature films on VHS. On systems containing Dolby Pro Logic technology, the audio is reconstructed to its original four-channel surround sound.

Dolby Pro Logic
Dolby Pro Logic decodes Dolby Surround movie content into four playback channels of surround sound: Left, Center, Right, and Surround. Dolby Pro Logic II Dolby Pro Logic II creates a captivating surround sound experience from any stereo (two-channel) movie, music, TV, or game audio source. Listeners will hear all the detail and subtleties of the original stereo content, with the added luxury of full, compelling surround sound that makes the entertainment experience feel as if it’s happening all around the listener.

Dolby Pro Logic IIx

Dolby Pro Logic IIx examines the signal and uses that information to expand audio into up to 7.1 channels of highly realistic, natural surround sound.

Dolby Pro Logic IIz
Dolby Pro Logic IIz introduces a new dimension to home theater listening through the addition of front height channels, creating a 7.1 or 9.1 playback system that enhances the spaciousness of music, movies, and video games. The height information complements the sound from the surround speakers while honoring the original intent of the content creator.

Dolby Headphone
Dolby Headphone creates a personal surround sound experience using any set of headphones. The playback of music, movies, and games results in sound that is more spacious, open, and dramatic, improving listening comfort and making listeners feel as if the action is happening all around them.

DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape – in front of, behind, beside and above the audience – more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits the space, from a television’s built-in speakers to a home surround theater system to a dozen or more speakers in a commercial cinema. With DTS technology, even the smallest screens will sound huge.

DTS HD Master Audio
DTS-HD Master Audio is capable of delivering audio that is bit-for-bit identical to the studio master. DTS-HD Master Audio delivers audio at super-high variable bit rates 24.5 Mbps on Blu-ray Disc which is significantly higher than standard DVDs. This bit stream is so fast, and the transfer rate is so high, that it can deliver 7.1 audio channels at a sampling frequency of 24 bits identical to the original. With DTS-HD Master Audio, you will be able to experience movies and music exactly as the artist intended: clear, pure, and uncompromised.

DTS HD High Resolution Audio
DTS HD High Resolution Audio can deliver up to 7.1 channels of sound that is virtually indistinguishable from the original. DTS-HD High Resolution Audio delivers audio at high constant bit rates superior to standard DVDs—6.0 Mbps on Blu-ray iscs and 3.0 Mbps on HD-DVD to produce outstanding sound quality. It is capable of delivering up to 7.1 channels at 96k sampling frequency/24 bit depth resolution. It allows content creators to deliver rich, high definition audio on movies where disc space may not allow for DTS-HD Master Audio.

DTS Digital Surround is the standard for providing 5.1 channels of discrete digital audio in consumer electronics products and software content.

DTS-ES is the only digital audio format capable of delivering 6.1 channels of discrete audio in the consumer electronics market. DTS-ES is also fully backwards-compatible with DTS decoders that are not Extended Surround equipped.

THX Loudness Plus
THX Loudness Plus is a volume control technology featured in THX Ultra2 Plus and THX Select2 Plus Certified pre-amps, integrated systems and receivers. With THX Loudness Plus, home theater audiences can now experience the rich details and ambient sound in a surround mix at any volume level.

THX Re-EQ is a compensation technology taking soundtracks that are mixed for large cinemas, where speakers are placed farther away from you, and re-establishes the accurate tonal balance for your close range home theater speakers. Without THX Re-EQ, higher frequencies sound excessively “edgy” or “bright.” With THX Re-EQ, the movie soundtrack is true to the original immersive cinematic experience.

THX Timbre Matching
Due to location, the tonal quality of the perceived sound coming from the side surround speakers is changed in relationship to the sound coming from the front speakers. This is because the outer ear, called the pinna, contours the frequency response of a sound depending upon its direction. The result is two conflicting sound fields – a front and a surround. THX Timbre Matching technology solves this sound field problem by actually acting as an electronic pinna, restoring and integrating the perceived frequency match between the front and surround speakers. This technology allows you to be placed in the center of the onscreen action with smooth, rich surround sound.

THX Adaptive Decorrelation
Many movie soundtracks have a mono surround track – especially those recorded prior to 1993. If you are sitting closer to one surround speaker than the other, the sound collapses to the one side instead of accurately immersing you in the onscreen action. THX Adaptive Decorrelation subtly adjusts one surround channel’s time and phase relationship with respect to the other surround channel. With THX Adaptive Decorrelation the listening position is expanded, providing you with the same spacious audio experience as in a movie theater.
