Why Atmos ??




Please note that the Dolby Atmos Mix on the Blu-ray is of much higher quality than its streaming counterpart. It is not compressed as it is on streaming platforms. Encoded in Dolby TrueHD Atmos it has a bit rate 10 times higher (up to 8000 kbits/s) than streaming’s Dolby Digital Plus (768 kbits/s).

Physical media haven’t said their last word: if you want to enjoy your music at maximum quality, you should choose CD or, even better, blu-ray, which is the “audiophile” medium, with no dynamic range limitations, and which contains the best stereo, 5.1 and Dolby Atmos versions. 
This Blu-ray Audio is an example to follow for other album productions, and let’s hope the majors follow suit!
