What can I say, I'm very happy at this point with LMS :-). This is about the same amount of peak processing as Brutefir digital room correction with high resolution PCM/FLAC files. With my i5-6500 (quad core, 3.2GHz) server machine, at most playback takes up 20% of the CPU cycles decompressing, transcoding, and downsampling to 88.2kHz when needed in the Linux/Ubuntu virtual machine. For example, in the picture at the top, the "Beethoven Dreams Stereo" track is reported as about 26 minutes when it should only be 3:18 (the fact that it's a larger DSD128 file magnifies the error as well).ĭecompression and transcoding remains quite efficient. So the album and song durations are not reported properly. The file library scanner knows about PCM WavPack but not DSD. So far, there's only one significant anomaly to be aware of. It does everything I want or need now including streaming DSD64 and DSD128 over DoP to my good ol' TEAC UD-501 DAC in use since 2013. ![]() A system to play compressed, metadata tagged DSD into the venerable Squeezebox Server / Logitech Media Server system. #LOGITECH MEDIA SERVER UPDATES INSTALL#So for example I'm using Ubuntu amd64, so I can grab the required libwavpack1_5.1.0-2_b here and grab wavpack_5.1.0-2_b here and install with: Grab pre-built binaries for your architecture. First, let's get the binary for WavPack 5 (currently the newest is 5.1.0). Now it's time to get our hands dirty into the Linux box and change some LMS settings (I'm currently running a recent nightly build - 7.9.1 - 1510723637_amd64 specifically). Of course the Raspberry Pi 3 / piCorePlayer config.txt had the CRAAP underclock/undervolt settings applied for "better" sound :-).ī. Also for my ALSA settings, I increased the buffer size to 120ms (from 80) just for that extra leeway. I don't know if this is the same with other devices, but I needed to put a value here otherwise the DAC doesn't switch into DSD mode properly. Note that I put in a 250ms delay switching between PCM and DSD. Since we're activating DSD streaming, might as well allow LMS to handle uncompressed DSD including transcoding to PCM for devices that are not DoP compliant. Although not necessary when it comes to WavPack, remember it's OK to turn on the DSDplayer plugin in LMS. Without further ado, let's get to the steps.Ī. If you're good with doing this, then proceed :-). ![]() Therefore in my library I have made sure that all my PCM music is encoded in FLAC, leaving WavPack to handle just DSD material. Remember that because WavPack can handle both PCM and DSD, it might get confusing if in your library there are both PCM and DSD music encoded in the WavPack format. The idea is to allow the LMS system to incorporate DSD into the library and stream DSD files compressed as WavPack to connected devices - ideally as DSD, otherwise transcoded to PCM. The hardware these days is my Intel i5-6500 server machine described here.įirst let me discuss what the aim is here. #LOGITECH MEDIA SERVER UPDATES SOFTWARE#For a description of the initial software install, have a look at my HOWTO: LMS + BrutefirDRC Plugin post from last year. #LOGITECH MEDIA SERVER UPDATES WINDOWS#Starting from the post by michaelvv on the Squeezebox Forum, I decided to spend more time on getting WavPack-DSD working in LMS and managed to get it working quite stably installed on a Ubuntu Linux (currently 16.04 LTS) virtual machine in the Windows Server 2016 computer that serves as my repository of data, movies, and music. In the right panel is the Logitech Media Server's interface where you can see that the mp3s with Korean characters are not displayed but those with regular alphabet characters are displayed just fine.PiCorePlayer streaming WavPack-compressed DSD128 (1-bit, 5.6MHz) to TEAC UD-501 from recent nightly version of Logitech Media Server 7.9.1.Īs I mentioned last time, it's great to see that DSD compression and metadata tagging are available in the form of WavPack 5. ![]() In the left panel is Windows Explorer where I have encircled the filenames that have Korean characters on them. I downloaded the latest beta (852) before posting here to see if it is resolved, but no luck there. I have been having this problem for a while. It also has no problem detecting mp3 files with regular alphabet characters whether I put them in a regular or a pooled drive. It can, however, detect the said mp3 file if it is stored on a regular non-pooled drive. It is unable to detect and scan mp3 files with Japanese or Korean characters (for example, 거짓말.mp3) when I put the mp3 file in a Drivepool drive. Hi, I am running Logitech Media Server 7.9 ( )īasically, it is a server that streams music to certain Logitech audio devices. ![]()
