      If it’s in Dolby digital plus, then it’s lossy. I’ve had it for ages as I’m on the beta versions. However it’s being delivered it sounds great!

      Yes it’s lossy but it sounds great. I watched A Quiet Place in atmos on the ATV and the sound was superb.

      I just read there that flatpanels hd say that it outputs in PCM as an uncompressed Dolby MAT 2.0 audio stream. Would you say that the sound is comparable to blu ray?

      Haven’t listened to a full movie yet, tbh. However it sounds great.

      Hmmm... tempting. I use the built in Plex client from my LG TV but this could be better....

      Does anyone know if this is a sneaky way to get better audio in general? I.e. if it can do Atmos then it can technically do TrueHD? If so, then this is a step up from what I currently get.

      This will be being transmitted in a compressed lossy format, will sound great, but I bet not as great as full fat from a BD/UHD DVD. Full Fat TrueHD ATMOS probably uses 3/4 times as much bandwidth as DD+ lossy. If they used full fat it'd probably take as much badnwidth on it's own as the whole film stream in total uses, so IMO is unlikely to happen... Can't wait for it still!! :)

      I use Plex on NVidia TV and find it a much more reliable Plex client to the Apple TV. NVidia supports TrueHD, ATMOS & DTS:X. My streamer of choice is Apple TV for everything else except my own ripped Blurays via Plex.

      ^^ This


      I've tried Plex on the TVOS 12 beta and it won't bitstream lossless atmospheric audio from UHD rips, Plex on the Shield TV is the only thing I've come across that will do it.

      This is slightly disapointing to hear, I was hoping the new update would help me make the nvidia redundant, I always find I can never find the perfect single device... :)

      It's doing lossy Atmos so no it won't be able to do TrueHD. From a bandwidth perspective it probably had to be done this way.

      I'd love avforums to do a comparison review between ATV4K (tvOS 12) iTunes movies with Atmos soundtracks versus the Blu-ray equivalent, in both high end home theatre and average Joe untreated front room 5.1.2 environments.

      The compression in broadcast ATMOS compared to uncompressed BluRay / UHD ATMOS will be similar in difference between compressed Dolby Digital and uncompressed Dolby TrueHD. Most AV enthusiast can tell the difference with ease and many can’t tell or aren’t so bothered.
      It’s similar in the music world to compressed Spotify / iTunes music and an uncompressed CD or Tidal HiFi. Some are bothered and want the best and can tell the difference, others don’t care or the lesser quality is perfectly fine for their needs / convienience.

      So Atmos is effectively a container format and the bitrate used in existing DD+ soundtracks will be identical? Will mastering be any different?

      Last I read about this Netflix was something like 192kbps for E-AC3 5.1. The difference between that and 320kbps OGG 2.0 (Spotify Premium) is far greater perceptually than between 320kbps OGG and FLAC (Tidal), IMO.

      I'd only be using it for convenient on-demand rentals because I don't trust streaming services for purchasing content but I'd still like something slightly better than potato audio.

      Taking a slight step back, what's the position regarding the audio streams from the Amazon and Netflix apps. over HDMI please? I've been putting off getting into 4K until kit with the new eARC facilities surface. My Amazon Fire box is starting to get temperamental and whilst I could replace it with something similar the Apple box would do just as well, as I only use Prime Video and Netflix. I can get the normal catch-up stuff elsewhere. Providing that I can get 5.1 audio from both apps on the Apple box it might be a better bet than another FireTV box.

      Cheers, Clem

      Not just DD+ but also (for Netflix but I'm sure Prime will follow) Dolby Atmos...It is the best video streamer by far when you put it all together :)

      That's a result if I can get DD5.1 audio from both Amazon and Netflix, because I recall that ATV boxes also have the NowTV app., which I fancy looking at. Connection-wise, I set my FireTV box to do 1080p/60, to get round the occasional picture judder from Amazon and Netflix. Will I have the same facilities on the ATV box, or does it rely on HDMI handshaking to set the screen resolution?

      Cheers again, Clem

      Bet setting on the AppleTV is to match the media frame rate and resolution in my opinion. Depending on your screen you may get a second of resync but it is worth it to run what you watch natively. It is smart enough to switch in app; i.e. one show can be in 4K HDR, the next could be in 24FPS 1080p, the next in 1080p but at 50Hz...etc...

      As I said, best video streamer by far :)

      Cheers, this for s sounding better by the moment. SWMBO has given the approval to flex the plastic so I can feel a trip to my nearest JL coming on in the next couple of weeks.
