Explanation of terms

Dynamic EQ solves the problem of deteriorating sound quality as volume is decreased by taking into account human perception and room acoustics.
Audyssey Dynamic EQ_® works in tandem with Audyssey MultEQ_® XT32 to provide well-balanced sound for every listener at any volume level.

Audyssey DSX_® is a new surround enhancement technology that raises the surround effect and impression to realize a larger surround space by adding a new channel to the existing 5.1 channel system.

In research on human hearing characteristics, two points can be broadly cited as elements that enhance the surround effect. The most important point is the creation of horizontal spread (wide channel) at the front (forward) area in composing a realistic surround space. The next important point is the creation of vertical spread (height channel) in the front (forward) area using recognizable (audible) acoustic signals so as to create a surround space with depth.

Audyssey DSX_® then creates a pair of Height channels to reproduce the next most important acoustical and perceptual cues. In addition, Audyssey DSX_® does not simply add a channel but combines the existing front, surround and rear surround sound to develop a technology known as “Surround Envelopment Processing” which has been incorporated into Audyssey DSX_® to further enhance the effect.

Dynamic Volume solves the problem of large variations in volume level between television programs, commercials, and between the soft and loud passages of movies. Audyssey Dynamic EQ_® is integrated into Dynamic Volume so that as the playback volume is adjusted automatically, the perceived bass response, tonal balance, surround impression, and dialog clarity remain the same.

Audyssey LFC™ solves the problem of low frequency sounds disturbing people in neighboring rooms or apartments. Audyssey LFC™ dynamically monitors the audio content and removes the low frequencies that pass through walls, floors and ceilings. It then applies psychoacoustic processing to restore the perception of low bass for listeners in the room. The result is great sound that no longer disturbs the neighbors.

Audyssey MultEQ_® XT32 is a room equalization solution that calibrates any audio system so that it can achieve optimum performance for every listener in a large listening area. Based on several room measurements, MultEQ_® XT32 calculates an equalization solution that corrects for both time and frequency response problems in the listening area and also performs a fully automated surround system setup.

The Auro-3D_® technology suite is a groundbreaking new audio technology that combines height-based listening formats with powerful creative tools to deliver an unrivaled three-dimensional sound experience. Auro-3D_® is the general format name for Sound in 3D and its related speaker lay-outs.

Auro-Matic_® up-mixing technology software is a unique creative tool that transforms legacy Mono, Stereo and Surround content into a natural 3D or 2D listening experience.

Introduced first in the cinema, Dolby Atmos brings a revolutionary sense of dimension and immersion to the Home Theater experience. Dolby Atmos is an adaptable and scalable object based format that reproduces audio as independent sounds (or objects) that can be accurately positioned and move dynamically throughout the 3 dimensional listening space during playback. A key ingredient of Dolby Atmos is the introduction of a height plane of sound above the listener.

Dolby Atmos content will be delivered to your Dolby Atmos enabled AV pre tuner via Dolby Digital Plus or Dolby TrueHD on Blu-ray Disc, downloadable files and streaming media. A Dolby Atmos stream contains special metadata that describes the positioning of sounds within the room. This object audio data is decoded by a Dolby Atmos AV pre tuner and scaled for optimum playback through Home Theater speaker systems of every size and configuration.

Dolby Digital is a multi-channel digital signal format developed by Dolby Laboratories.

A total of 5.1-channels are played: 3 front channels (“FL”, “FR” and “C”), 2 surround channels (“SL” and “SR”) and the “LFE” channel for low frequency effects.

Because of this, there is no crosstalk between channels and a realistic sound field with a “three-dimensional” feeling (sense of distance, movement and positioning) is achieved. This delivers a thrilling surround sound experience in the home.

Dolby Digital Plus is an improved Dolby Digital signal format that is compatible with up to 7.1-channels of discrete digital sound and also improves sound quality thanks to extra data bit rate performance. It is upwardly compatible with conventional Dolby Digital, so it offers greater flexibility in response to the source signal and the conditions of the playback device.

Dolby surround is a next generation surround technology that intelligently up mixes stereo; 5.1 and 7.1 content for playback through your surround speaker system. Dolby surround is compatible with traditional speaker layouts, as well as Dolby Atmos enabled playback systems that employ in-ceiling speakers or products with Dolby speaker technology.

A convenient alternative to speakers built into the ceiling, Dolby Atmos Enabled speakers employ the ceiling above you as a reflective surface for reproducing audio in the height plane above the listener. These speakers feature a unique upward firing driver and special signal processing. These features can be built into a conventional speaker or standalone speaker module. The features minimally impact the overall speaker footprint while providing an immersive listening experience during Dolby Atmos and Dolby surround playback.

Dolby TrueHD is a high definition audio technology developed by Dolby Laboratories, using lossless coding technology to faithfully reproduce the sound of the studio master.

This format provides the facility to support up to 8 audio channels with a sampling frequency of 96 kHz/24 bit resolution and up to 6 audio channels with a sampling frequency of 192 kHz/24 bit resolution.

Gives you control of the listening experience. You can lift the dialog out from the background sounds when clarity and intelligibility are desired.
This requires that content has been authored to support Dialog Control.

Sampling involves taking a reading of a sound wave (analog signal) at regular intervals and expressing the height of the wave at each reading in digitized format (producing a digital signal).

The number of readings taken in one second is called the “sampling frequency”. The larger the value, the closer the reproduced sound is to the original.

This is an AC resistance value, indicated in Ω (ohms).

Greater power can be obtained when this value is smaller.

This function operates automatically during playback of Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS or DTS-HD sources.
