Jdiesel 1176 Posted September 29, 2019 Share Posted September 29, 2019 Just as a test, what happens if you cast the audio file directly to the Shield TV from a web browser or mobile app? What I mean by this is to not use the ATV app but the built in Chromecast functionality of the Shield TV itself? Does it play correctly? I seem to remember my Chromecast audio working correctly but maybe it wasn't 24bit/192hz Link to comment Share on other sites More sharing options...
Bill4sman 10 Posted September 29, 2019 Author Share Posted September 29, 2019 (edited) That actually works rather than playing directly from Emby WHICH is why I know it can do what we want if a programmer will not pass it off to ffmpeg.

Guest asrequested Posted September 29, 2019 Share Posted September 29, 2019 That actually works rather than playing directly from Emby WHICH is why I know it can do what we want if a programmer will not pass it off to ffmpeg. It isn't the server/ffmpeg. The Android TV app is using Android's Exoplayer. It is that player that is re-sampling the audio, internally. That's what ebr was trying to explain. That's why I made my post showing that when I played your file on my HTPC with the Emby app, from either server, it played correctly. As mpv (the player that is used in that app), can correctly decode it, and my equipment supports it, so it doesn't get resampled. If Android/Exoplayer don't/won't allow it, I'm not sure what ebr can do to change the output. You can read about what Exoplayer supports, here. https://exoplayer.dev/supported-formats.html Link to comment Share on other sites More sharing options...

pwhodges 1697 Posted September 29, 2019 Share Posted September 29, 2019 I PROMISE you can DEF hear the difference between a 320kbps file and a 192/24bit one on my system without fail. Of course; but comparing lossy and lossless data is a completely different issue from the 16/24-bit comparison. As for 192kHz sampling - you do know, I hope, that audio microphones roll off at about 20kHz anyway, so sampling at a higher rate than 48kHz isn't actually getting you any more information.

Bill4sman 10 Posted September 30, 2019 Author Share Posted September 30, 2019 (edited) That also doesn't jive with the fact that I can get 192/24 out of the Shield through other software so I'm not 100% on this being the roadblock. Also, this informaiton doesn't reference 4K video so may be rather dated? Why is Emby using a player that's stuck 6 Android versions ago???

ebr 15282 Posted September 30, 2019 Share Posted September 30, 2019 Why is Emby using a player that's stuck 6 Android versions ago??? We're not. We are using the player built by Google specifically for this platform (and that is also used by many major products). But, the device and platform are built for streaming media and there simply is no streaming media that has the exact characteristics of what you are trying to play.

Bill4sman 10 Posted September 30, 2019 Author Share Posted September 30, 2019 That's good news at least. Probably explains why Plex is not playing this level of HiRes either... Link to comment Share on other sites More sharing options...
Deathsquirrel 743 Posted October 1, 2019 Share Posted October 1, 2019 24-bit vs 16-bit is important in music recording and production, but its benefit in delivery is really marginal. Indeed, studies in which a 24-bit feed was compared with the same feed reduced to 16-bit and then delivered as 24-bit so that the user couldn't see have failed to find an audible difference. I agree it would still be good to deliver the 24-bit file correctly, but it's really not something to get excited about. [Note: I used to be a recording engineer.] You clearly weren't using the right cables in your testing. You needed MUCH more expensive ones. Also you nee a healthy set of magical ears that can easily detect differences in audio sample rates way above the limits of human hearing as long as you aren't testing or measuring anything scientifically. It's like the invisible boy in Mystery Men. Audiophile ears only work when no one is listening... Link to comment Share on other sites More sharing options...
Guest asrequested Posted October 1, 2019 Share Posted October 1, 2019 I know a few audiophiles with $100,000+ listening stations, that absolutely refuse to listen anything digital. They will only listen to vinyl, and they spend hours fine tuning the stylus, to get specific frequencies. I also know someone who is paid and flown around the world to re-adjust listening stations.

Given that most music production has been digital for a long time, even when vinyls are manufactured as a by-product, they must have a pretty limited choice of listening.

Bill4sman 10 Posted October 1, 2019 Author Share Posted October 1, 2019 (edited) the goal of "stereo" is to reproduce a live recording so WHY would you NOT want the ENTIRE recording regardless of whether anyone says you can hear it? These are the same people that would likely argue about CD's sounded better than vinyl. Again, if you're listening to this through your TV I'm fightingt a losing battle. I and many others want the best possible audio we can get. Edited October 1, 2019 by Bill4sman Link to comment Share on other sites More sharing options...
pwhodges 1697 Posted October 1, 2019 Share Posted October 1, 2019 My equipment is secondhand from BBC Radio 3 studios. My own recordings are in full true 3D surround - i.e. recording and reproducing the whole sound, not just a horizontal sliver of it. That makes a lot more difference than 16 vs 24 bits!

People like that are also collectors. They find rare pressings. They have rooms filled with vinyl. Link to comment Share on other sites More sharing options...
