Dolby Atmos is all over the place. I’ve seen wi-fi audio system and soundbars with Dolby Atmos help. I’ve used streaming companies touting spatial audio powered by Atmos. Most lately, the brand new Motorola cellphone I am reviewing has Dolby Atmos audio system. Frankly, I feel Dolby is taking part in too free with the Atmos model. If the catchy identify is on mainly each audio product and streaming service, it is arduous to know what seeing the Dolby Atmos emblem truly tells you. The one factor you must learn about Dolby Atmos is that not all Atmos content material is identical high quality.
