Surround replay systems may make use of bass management , the fundamental principle of which is that bass content in the incoming signal, irrespective of channel, should be directed only to loudspeakers capable of handling it, whether the latter are the main system loudspeakers or one or more special low-frequency speakers called subwoofers. Though this is a lossy scheme, yet at this relatively high bit rate, there is hardly any discernible difference between the original soundtrack and the reproduced sound after decompression. Windows at that point takes over and will up-mix if you’ve enabled virtual surround, otherwise that can be left to your external amp. The function of the center channel is to anchor the signal so that any central panned images do not shift when a listener is moving or is sitting away from the sweet spot. Placing audio content on the filmstrip itself has got its pros and cons. With 6 or more speakers arranged around a listener, a 3-dimensional “periphonic”, or full-sphere sound field can be presented.

Films is where it gets a little more complex largely due to the various and evolving container formats, such as MKV and additional digital audio standards such as Dolby TrueHD.
List of digital television deployments by country. You may need to dig out your motherboard manual for a complete pin-out. Delivering the Sonic Goods”. The latest Blu-ray releases tend to stick to one or the other for their highest-resolution option, either TrueHD or Master Audio, then defaulting to a more compressed option like standard Dolby Digital 5. soudn
This section needs expansion. DTS sound formats arises in the way these are implemented in movie theater applications. With games, audio adds vital subtle clues as to your enemy’s whereabouts and actions that visuals just can’t do. Blu-ray and HDMI are designed to carry a number of standard multi-channel sound formats, we’ll list them in order of increasing bit-rate: DTS, both make use of lossy compression techniques since the final decoded audio data can never represent a perfect image of the original source content.
DTS (sound system)
Then check out LoveFilm vs Netflix: Wikibooks has more on the topic of: In other words, under a multi-channel scenario, compression becomes a necessary evil. In”surround sound” successfully reappeared with the film “This is Cinerama”, using discrete seven-channel sound, and the race to develop other ets sound methods took off.
The Logitech Z 5. However, there 55.1ch more ways to create surround sound out of stereo, for instance with the routines based on QS and SQ for encoding Quad sound, where instruments were divided over 4 speakers in the studio. This technique therefore resembles back to back near-coincident stereo pairs. This method allows backward compatibility.
The first documented use of surround sound was infor the Disney studio’s animated film Fantasia. However, this difference is not one surgound the main issues that are fuelling this Dolby vs.
The Ambisonics form, also based on Huygens’ principle, gives an exact sound reconstruction at the central point; less accurate away from center point. The theatrical DTS processor acts as a transport mechanism, as it holds and reads the audio discs. With 6 or more speakers arranged around a listener, a 3-dimensional “periphonic”, or full-sphere sound field can be presented. We’re glad you surrpund. This is achieved by using multiple discrete audio channels routed to an array of loudspeakers.
Dolby Atmos uses a similar technique,   although the speaker layout employed by cinema DTS: This soundtrack is output via digital coaxial or optical audio outputs and requires an external decoder to process the bitstream. Independent control of the sub-bass effects also reduced the problem of intermodulation distortion in analog movie sound reproduction.
Surround sound – Wikipedia
Many recordings do not require pickup of side reflections. Another cause for confusion is when it comes to DVI, technically DVI isn’t designed to carry audio, however it is pin-compatible with HDMI and if those wires transmit the correct digital audio and video data, no-one and no-device would be the wiser with it all working seamlessly.
Matrix systems recover the number and content of the source channels and apply them to their respective loudspeakers.

Any channel configuration may include a low frequency effects LFE channel the channel played through the subwoofer. Studios have to pick and choose which formats to support on each release, and at which maximum quality. The number of bands steered varies in each Neo: Spatially augmented audio delivery:
