Sound high-altitude flight with devil and Dolby Atmos The Atmos loudspeakers are oriented towards the ceiling and are configured in such a way that the sound effects arrive at the listener’s seat as height effects.ĭolby Atmos as standard is downward compatible and is also reproduced by a conventional 5.1 system – but without the corresponding signals for the ceiling speakers. The secret of the process lies in the targeted use of sound reflections. The suggestion not to place the Atmos loudspeakers on the ceiling does not sound entirely conclusive at first – after all, the sound effects should sound as if they were coming from above. The additional high-frequency loudspeakers can either be mounted on the ceiling or in the room or on front or surround loudspeakers. The surround loudspeakers remain in place. Dolby Atmos integrated into Home CinemaĪtmos home cinema systems usually combine 5.1 or 7.1 sets with additional speakers for the height dimension. The foundation or the so-called sound carpet still consists of a classic 5.1/7.1 construct. An explosion on the left side of the screen is now simply defined as a sound from a certain position on the left. When filmmakers now produce in Dolby Atmos, they can spatially represent these sound objects without having to commit to a specific channel. Dolby Atmos, on the other hand, can work with a set of at least eight (5.1.2) speakers as well as up to 32 channels. This limited the manufacturers of home cinema systems in that they could only use a specified number of speakers. If the sound of an explosion visible in the left half of the picture was to be heard on the left side as well, the front and rear loudspeakers on the left side had to be controlled with corresponding sound data. Each channel or loudspeaker was assigned its own audio information. With the “old” Dolby standards for 5.1 or 7.1 systems, the sound was mixed exactly for the six or eight channels available. Object-based instead of channel-based – the technology behind Dolby Atmosĭolby Atmos, unlike its predecessors, works not only channel-related, but also with so-called sound objects. However, the standard is not widespread there either – see the new Dolby cinemas in the UK here. In addition, some film titles are also available on Netflix with Atmos sound – if certain requirements are met.Ītmos has long been used in large commercial cinemas. The number of Blu-rays with Dolby Atmos sound track is now considerable. A loudspeaker set licensed for Dolby Atmos.An A/V receiver that can decode Dolby Atmos.These are the essential requirements for Dolby Atmos: Its ease of integration could have contributed to its success. And so it’s not surprising that the 3D sound standard has quickly established itself. Already people started claiming that Atmos would be the biggest innovation in home cinema since the introduction of surround sound systems in the 1980s. A/V receiver manufacturer Onkyo made the first move. The first Atmos systems came onto the market in 2014.
