What is Dolby Audio

The Dolby Universe

Anyone who is even marginally interested in good sound cannot ignore Dolby technologies. The company was instrumental in helping surround sound spread to cinemas and living rooms; It designed the transition from analog to digital surround sound, made surround sound easier to access and most recently presented a playback method for 3D sound with Atmos. Here you can see an overview of the individual Dolby standards.

Ray Dolby - a name that stands for good sound

Without Ray Dolby, the world of audio technology would be different today. He was Visionary, inventor and founder of the most important company for analog and digital audio formats. With his company, the Stanford graduate established the first methods of noise suppression and significantly advanced the development of surround sound. It was his special claim that his inventions should also find distribution among private listeners.

Dolby Surround

We perceive noises and sounds spatially, so we can say exactly where a sound source is and how it moves. For a long time this was not possible with recorded sound. Dolby Surround provided a remedy here: Introduced in 1982, the analog playback method initially supported 3 channels, a fourth channel was added after an update in 1987. The technology is based on one Matrixing process, with which the information for 4 channels is saved in 2 audio tracks. Today the process only plays a role in vintage plants. Matrixing, on the other hand, is also important in times of digital audio information. The storage method is used, for example, in the new versions of Dolby Pro Logic.

Dolby Pro Logic II

The Dolby Pro Logic standards are Surround buff. They prepare audio data that is actually only available in stereo for playback on surround systems. The current standard Dolby Pro Logic IIz even supports 9.1 set-ups. The "upmixing" also works if the audio data is available for a 5.1 configuration. Dolby Pro Logic is integrated in many of our decoders so that multi-channel systems can be fully played out. This includes our high-end AV receiver Complete 7, the DecoderStation 7 and the Concept E 450.

Dolby Digital (Plus)

When Dolby Digital first established itself in cinemas and then in living rooms in the 1990s, it meant that Transition from analog to digital surround sound. The lossy digital playback method supports 5.1 channels and is the standard on DVDs. A further development is Dolby Digital Plus. This potentially supports 13.1 channels and was developed for playback on HD televisions and for online content. Dolby Digital Plus requires less bandwidth and enables better sound quality. The Complete 7, the DecoderStation 7 and the Concept E 450 have a Dolby Digital decoder on board.

Here we present Dolby Digital Plus in detail.

Dolby E

With our contribution to Dolby E, we are on the side of the Sound production looked. The codec enables the storage and processing of audio data. The data is stored in a maximum of 8 channels and can be edited independently of each other. A particular advantage is the coupling of the audio data to the images. That simplifies the editing of the pictures considerably. The codec can also be used to output standards such as Dolby Digital, including the associated metadata.

Dolby Virtual Speaker

Strong surround sound without a 5.1 system? This is exactly what is possible thanks to Dolby Virtual Speaker (DVS). Stereo systems and soundbars also use this playback method a room-filling surround soundin which the listener perceives sound events that play to the side and behind him. To do this, the audio signals are modulated in such a way that we perceive so-called virtual sound sources. A decoder for DVS is integrated in the Cinebar 21 and the Cinebar 52 THX.
How the generation of virtual sound sources works is explained in the article on Dolby Virtual Speaker.

Dolby True HD

Dolby True HD is a digital multichannel Dolby standard with which the audio data without data loss arrive at the listener. The process was developed for the Blu-ray Disc. This offers sound engineers enough space to store all data using intelligent storage methods. Our AV receivers Complete 7 and DecoderStation 7 naturally also support this Dolby standard. However, it is largely left behind against its competitor DTS HD-Master.

Dolby Atmos

With Dolby Atmos, the Californians have once again achieved a real coup. This standard extends the soundscape by the height dimension. If something happens above our heads on the TV display, we can also hear the corresponding sound from above with Dolby Atmos. Dolby relies on a new, object-based playback method. With this method, the 3D sound can be reproduced with a 5.1.2 system - provided the loudspeakers are prepared for Dolby Atmos and a corresponding decoder is available. The LT-5 loudspeakers licensed by Dolby Atmos prove how good 3D sound can sound from such a system. The 3D standard is also used in a number of Dolby Atmos cinemas.

Dolby Vision

With Dolby Vision, Dolby is trying to set standards in video playback as well. The standard is used for television pictures with a particularly high contrast range (HDR). It is now becoming apparent that the standard is being adopted by film producers and equipment manufacturers, although there is also a competitor for Dolby's "highly dynamic" image format.
Here we present Dolby Vision in detail.
