AppleInsider:

Netflix on Wednesday launched what it calls “high-quality audio,” offering crisper sound for viewers with surround-sound systems. Compatible videos are labeled for Dolby Atmos or Dolby Digital Plus 5.1, Netflix said. This includes videos that only have a “5.1” emblem. Both standards are supported by the Apple TV 4K, but only Digital Plus 5.1 is available on the Apple TV HD.

Quality is moreover adaptive based on bandwidth. 5.1 systems will get bitrates spanning 192 kilobits to 640 kilobits — which Netflix calls “perceptually transparent” — while Atmos systems will start at 448 kilobits and reach as high as 768. Atmos does require the company’s Premium plan, which costs $15.99 per month but is also needed for 4K.

Just out of curiosity, how many of you have a system that can take advantage of this new “‘high-quality’ audio” for your Apple TV?
