Can anyone tell me what my RPi3B/Digi+ Pro (running Moode 3.1) is doing when it decodes and processes this MP3? What sort of resampling operations are being performed (see first image), and are they being performed by the RPi3B by the DNLA server, or both? The track is a 192 Kbps MP3 downloaded from Freegal (a service offered by many public libraries in collaboration with Sony Music Group). It's encoded with LAME, I'm not sure whether constant or variable bitrate. I'm fairly confident that it is 16 bit, not 24 bit. (I've never heard of a 24 bit MP3.) The server is a Mac Mini running El Capitan, and the Apple MIDI control panel is set to 24 bit 192 kHz output, with an Ethernet connection to my home router. Server software is Kodi 17.1 configured for DNLA. DNLA control point is 8player running on iOS. (The reason for the MIDI control panel setting is that I occasionally use the Mac Mini for direct playback.) For comparison, the 2nd and 3rd images show playback of an ALAC ripped from a CD and a hi-res FLAC downloaded from HDtracks using the same setup. Thanks for any insight!
Apologies up front if there is a more appropriate forum to post this in. It crosses several topics (networked audio, equipment, software). Bottom line up front: I’m looking for an alternative to my current Mac Mini / JRiver - based music server setup that is more stable. I leave the computer on 24/7, with JRiver running, and I expect to be able to playback music using my iPhone running JRemote whenever I want to listen to something. This works more often than it doesn’t, but too often I attempt to play music via JRemote and get nothing, at which point I turn on the TV only to discover the Mac has thrown a dialog box or an error or JRIver has crashed. Once I clear out the dialog box / error window and if necessary relaunch JRiver or reboot, the system works as designed. This happens often enough that I want a solution that is more stable, preferably using the same hardware I already own, but if necessary I’d switch hardware. To be very clear, I’m not looking for new functionality or improved sound quality, just better stability. Setup: Mac Mini (2011) with 8GB RAM running OS X El Capitan and JRiver MC 21. The monitor is my main TV which I use to watch video. Music is stored on a 3TB local external hard drive that is connected to the Mini via Firewire 800. The Mini is connected to a 802.11ac router via ethernet cat 6. It feeds two separate music systems via USB 2.0 (one home theater / stereo, one headphone rig). Additionally, there is a 3rd system that I stream music to over my home network via DNLA. I use an iPhone running JRemote as my primary controller, again via DNLA. Uses: 90% listen to 2ch music stored on the hard drive on one of the three systems I already mentioned (two connected to the Mini via USB, one remote system that streams from JRiver). 9-10% streaming video over the internet (I do the vast majority of my video watching using a Roku rather than the Mini, but I’ll use the Mini to watch sources that aren’t compatible with the Roku). 0-1% Multi-channel video content. On those rare occasions where I watch multi-channel via the Mini, I use XBMC for OS X rather than JRiver. I do this infrequently enough that I don’t mind the process of quitting JRiver, modifying the necessary configurations on the Apple MIDI utility, and launching XBMC, then when I’m done reconfiguring the system for music / 2ch. Any suggestions? Would running XBMC on Linux and using it for music playback offer me the stability I’m looking for? (I could always boot back into OS X when I want to use the computer to stream video over the internet.) Other ideas? I really am hoping to avoid buying a dedicated music server, though that’s probably the solution that would offer the most stability. Thanks, and if anything in my description is unclear, or if there is additional info you need me to provide about my system or how I use it, just let me know.
