      Sneaky Netflix rolled out these higher bitrates 9 months ago, but are only announcing them now, very interesting...

      It is indeed interesting... here's a thought - I subscribe to the top tier to get 4k, but I also want (obviously) the best audio too. This package also gives me 4 x simultaneous user/streams - and that's something we never really use.

      9 times out of 10 we watch Netflix on our top-end system (i.e. 65" oled with decent surround sound), and only very rarely on one of the other TVs or my office PC. I would gladly trade this "down" to 2 simultaneous streams so I could get even higher audio on my main system.

      I wonder how many others here that subscribe to the 4k package feel the same way? (Or perhaps those that don't yet have a 4k display but would trade up anyway to get the higher-quality audio?)

      Can they now increase the video quality, they should double the bandwidth from 15 to 30 Mps for HD and 25 to 50 Mps for UHD.

      Sorry to say but their UHD streams are ~15Mbps

      They recommend a 25Mbps connection so you have some overhead, the actual stream is less:

      I'd love to take advantage of the high quality audio - I have ps4 pro, sony smart tv, sky q. None of those offer the high quality audio. I'm not paying for another tv for a while so nice news and that but a tad bit frustrating.

      According to the Verge write up of this, the audio stream is not dynamically adapting.

      When you start to stream a show, it has a look at the bit rate that can be delivered, and sticks with that. So if you are having a bottleneck in your wifi speeds at that moment, but which clears, say, 5 mins later, it won't readjust to improve the audio stream.

      Anyway, baby steps I guess.

      Ideally they would offer a lossless tier for people with the bandwidth and for a few extra quid. I suppose they judge the economics don't work yet. But honestly, that would kill off disks for me. I'm already pretty happy with picture quality from Netflix.

      I cant see any streaming going lossless, the bandwidth needed would be astronomical for the business benefit to Netflix

      Just think it through - enough people would need to be able to hear the diff, and would need the right equipment, and broadband speed, the ISPs would need to provide that bandwidth, and Netflix servers too. So when you think about it its not going to happen.

      Its a shame because the audio diff between disk lossless and even the new Netflix is huge despite them trying to say that its indistinguishable from source.

      In any case DD+ can go up to 6M so they're still using only an 8th of its capacity.

      Those with eARC still won't benefit as the audio bit rate is still under 1 Mbps.

      I don’t know if this is related by I’m having audio drop out issues since yesterday. Only on one title (Lunatics) but it’s something that’s never happened before. My Denon receiver is behaving as if the stream is switching between stereo and 5.1 sound. It can happen in quick succession or be fine for 15 minutes then just happen. I have fibre to the door 150mbps my connection is rock solid, and as mentioned, it doesn’t seem to affect 5 or 6 other titles I’ve tested (I’m trying to select 4K 5.1 titles for a like-for-like text).

      Puts some nice pressure on Apple to up their standard sound when they launch their made-for Apple TV programs etc. subscription streaming service

      Have found that Netflix (I have the premium) on the Apple TV is better audio wise (I have Atmos too) than other any device I have used i.e Bluray player, TV app or even from the firestick.
      Even better when Dolby Vision is available too.

      They just need to up the bitrate now on UHD content to around 50.. We have more bandwidth now available then a couple of years ago.
      Youtube is already unrestricted in that department, I watched the champions league final on there last year in 4K and it was mindblowing.

      It's showing up on my Windows 10 Netflix Apps.

      Still 192kbps audio.

      Its down to the streaming provider. They could stream lossless which usually contains the lossy core but not sure if this is different to BD players.

      What's the audio bit rates on iTunes 4K movies on Apple TV?

      The actual bitrates dont justify the headline grabbing press release with delusions of source identical sound quality.

      Streaming audio quality is nowhere near what you'll get from bluray or UHD bluray - you have a setup problem if you think otherwise. The Atmos output from ATV 4K to a receiver for Itunes and Netflix is about the best sounding for streaming services though.

      No chance of lossless audio on streaming or bandwidths at 50M etc etc. Netflix is a business serving whole films etc - not ad-revenue-generating 3 minute long demo clips that Youtube can supply at highish rates.

      Rather than just publishing these press releases forums and websites should push back on providers and query why so little of the 6M capacity of DD+ is being used despite the impending price hike to £13 or so.

      Wow, didn't realise it's that low, they definitely need to increase that to get a better, stable image. You can bet Disney are gonna go all out on PQ and AQ for their streaming service.

      Honestly watching something like Altered Carbon on over Netflix in 4K HDR the last thing on my mind was I wish this had a higher bitrate. Infact its one of the best looking shows on both streaming and bluray to me. Not many have wowed me like that did. Sure higher bitrates are always nice especially if you have room to spare but watching that show its still to me one of the best looking 4K HDR shows out there. Audio wise sure that can certainly be improved..but picture wise I felt it was stunning.

      384 Kbps lol. It used to be good 20 years ago but now mate.

      640 Kbps DD should be good.

      I don't have any complains as Apple are probably one of the best in updates. Of course it could be better. Definitely dolby atmos and dolby vision is top drawer.

      I have a really medium quality Atmos set up, so the difference between Apple Atmos & Disk Atmos is noticeable but not massive. However I can really hear the difference on none Atmos Apple Movies versus the Disk. Would really appreciate it if they stepped that up

      The Atmos on Netflix's The Wandering Earth Review is as good as Ive heard on Netflix (via ATV 4K) and the DV also (at least as good as Altered Carbon)

      Apart from tweaks I cant see any significant changes to Netflix video/audio for some time to come. To be fair its content that really matters - there's some good stuff on NowTV even if the AV quality is far behind Itunes/Netflix (and Disney too probably)

      All the films I’ve watched sound like crap compared to their disc counterparts. The compression just completely fills the sound, I’d go so far as to say even DVDs sound better!

      I dropped down from the top tier 4K package back to HD as I just didn’t feel it was worth it especially if you don’t really watch the Netflix shows.

      Indeed - Recently, I tried to watch Lord of the Rings (hadn't seen it 10 years or so) on Netflix.

      The dialogue was so low in the mix, so hard to hear properly on my 5.1 system, I gave up and put in the DVD's, which I had lying around....soooo so much better audio wise.
