Surround/Immersive Sound involves the whole audio ecosystem! But this feature requires a good deal of improvisation in the production workflow and infrastructure all across the ecosystem and not yet widely prevalent. Consumers can switch off / on or play up / down the volume of different audio objects based on their needs, preferences, hardware capability, or listening environment.įor example, many listeners might want to boost the dialogue a bit. The term “object-based audio” is also used for immersive sound technologies as they allow modeling of sound sources along with their coordinates in 3D space as “objects.” This differentiates them from earlier “channel-based” surround sound technologies where directors had to mix the sounds from a scene into pre-determined channels.Īudio objects also open up possibilities for the personalization of audio delivered to consumers. The following figure shows the recommended layout for a 5.1 speaker surround sound system.Ĭheck out this link on Dolby’s website for some expert advice on speaker placement for surround and immersive sound effects. The 5.1 system is widely used in home theaters. “5.1” indicates that it has five main (full audio spectrum) channels and one low-frequency enhancement (LFE) channel. The most common surround sound speaker layout is “5.1”. Difference between 5.1 and 7.1 Surround Sound Surround sound systems extend the “sound field” to all directions surrounding the listener, including the sides and rear, by using additional speakers placed strategically. However, this configuration can create perceptions of left and right directions. Sounds produced by stereo systems, comprising of a left and a right speaker, can only seem to originate from the front of the listener. The term “surround sound” is used to describe sound systems capable of producing a sensation of sound from all directions surrounding the listener (i.e., 360 degrees) at ear level.

Netflix I have on my TV so I get proper 5.1 so that is ok and so is my Sky Box. So the trade off is either a 5.1 sound signal from the splitter which translates into Centre and Front Left and Right speakers which is top quality sound and immersing or go for 2 channel signal form the splitter which my system splits into Centre, Front Left and Right and Rear Left and Right which is also a very good sound but not quite the clarity or punch. I guess the preview was in fact a stereo signal which my system split into 5.1. Got excited for a minute nad then put the film on to see and it was 3 speakers.
I had it set on digital when a preview came on an amazon movie and all 5 speakers were working.
I can only get Centre and front speakers with digital 5.1 streams. The 640 kbps bit rate, which is higher than the standard 448 kbps used on DVDs, is fully compatible with all existing Dolby Digital decoding products such as A/V receivers, and can provide higher-than-DVD quality from Dolby Digital Plus soundtracks when played back through existing systems." Dolby Digital Plus soundtracks are easily converted to a 640 kbps Dolby Digital signal without decoding and reencoding, for output via S/PDIF.
" Is Dolby Digital Plus content backward-compatible? Because Dolby Digital Plus is built on core Dolby Digital technologies, content that is encoded with Dolby Digital Plus is fully compatible with the millions of existing home theaters and playback systems worldwide equipped for Dolby Digital playback.
