This uses virtual sound delivery and software smarts to take advantage of your current sound system to offer immersive virtual surround. While Dolby Atmos requires upfiring speakers to bounce audio off the ceiling, or ceiling mounted speakers, for an immersive, above-you-sound experience, DTS:X does not. At time of publishing all streaming services only offer Dolby Atmos. While there are discs with Dolby Atmos and discs with DTS:X, you won't find both on the same disc, it's one or the other. While Netflix now offers Dolby Atmos sound and some 4K Blu-rays will do the same, for DTS:X you'll need to go solid state. Winner: 4K Blu-ray 4K Blu-ray vs streaming - Sound qualityĪudio quality is an area that varies across 4K Blu-ray and streaming services. Of course we say limited, but in reality as broadband connections get better and the streaming compression becomes smarter this will only get better and better with no real limits. Lastly there is frame rate, with 4K Blu-ray able to support up to 60fps where most streaming services are still limited to 30fps. 4K Blu-ray varies but there are lots of titles with Dolby Vision and plenty with HDR10+. Amazon Prime Video supports HDR10+ (10-bit color) while Netflix and Disney Plus use Dolby Vision (12-bit color). ![]() HDR10 is pretty much available on all discs and streaming services but this doesn't have the frame-by-frame adaptation tech that HDR10+ and Dolby Vision offer. Both streaming services and 4K Blu-ray offer HDR but the type varies. However it's limited only to Sony Bravia Core 2021 TVs, for now.Īnother area to consider is HDR. Honestly, if I can't resolve this, I'll just live with it.There is one exception to streaming, in the form of Sony Bravia Core which is a Sony movie streaming platform that offers 80Mbps. Also, good to know that you detect minute differences with native 96kHz. To get close to CD quality (16/48 is roughly that) when you paid for 24/96 is a bummer. The reason I'm troubleshooting this is not because there is degradation in the sound quality (through headphones, the 24/48 sounds good), is because the Blu Rays were purchased for hi-res, were advertised as hi-res, and it's somewhat of an annoyance that they're not playing as intended/advertised. So, that shows that the player and optical connection to the ADI2 DAC are capable of this resolution transfer and it shows that there's something up with the Blu Ray discs. Oddly, I have a couple of DVD-A discs (from King Crimson box sets) that are labeled as 24/96 and it will be properly received by the DAC as 24/96. For those discs with audio setup, I will choose 24/96, but my DAC will see it as 24/48 or in one case 16/48. Thoughts on the resolution and just sticking with whatever the DAC reads, are also welcome.Ĭlick to expand.A few discs are just LPCM stereo 24/96 and others have audio menus where you can select 5.1 or LPCM 24/96. If I were a dolphin, sounds above 44.1 kHz are detectable, but not music, correct? I read the Nyquist article a while back.Īny recommendations regarding my Blu Ray player, replacing it, routing through an HDMI extractor, etc. Lastly, if I have music on the BluRay disc in 24/96 resolution, and it's downsampled to 16/48 on my DAC, do my ears notice a difference? I believe 16/44.1 is as good as the human ear can hear. Second, I might need a new/better Blu Ray player, but have no clue what brand/model that would be. Better yet, how do I correct it? I've read I could try and HDMI extractor and see if I can get the audio signal from the HDMI output and transfer it to the DAC via optical cable. I'd like to know the science behind transfer of digital audio from the source to the DAC and what is happening in this signal chain to account for the downsampling of the music. No matter how I set the player's settings, this is the result. However, when I play them on my Blu Ray player (Panasonic DMP-BDT360), the screen says LPCM 24/96, however my RME ADI2 DAC connected via optical cable, reads 16/48 and sometimes 24/48. My scenario: I've got several Blu Ray and DVD-A discs from a few bands that I really like, many of which have music in 24/96 resolution. I think I may know the answer, but I really do value the opinions on this Head-Fi subform, as I always learn some great information. ![]()
