I haven't tried DSD 512 Stereo files with Roon, but the ones from NativeDSD work with JRiver Media Center 26 for Windows (64 bit version) as well as HQ Player 4 Desktop here.  I've also successfully played the NativeDSD Stereo DSD 512 files with Tune Browser for Windows. 

 

As for Audirvana for Windows, I've had it crash on files at lower bit rates than DSD 512.  So I stopped using Audirvana here.

 

Thanks for the response. Yes I don’t know what the difference could be between the NativeDSD 512 files and the ones I’m producing with HQPlayer Pro on my MacBook Pro, unless it is an unintended byproduct of the trial version that I’m using. 
 

I was only using Audirvana as a front end via UPNP to my HQPlayer OS server when I wanted to play files on my MacBook that I hadn’t transferred to the NAS that Roon and HQPlayer use as a library. I don’t use Windows.
 

My main reason for trialling HQPlayer Pro was to see if I could produce files to use with Roon without the HQPlayer server in the chain.

Has anyone worked out why 512DSD files produced with HQPlayer Pro won't import into Roon or why they crash Audirvana (which shows them as 557DSD)? I've tried editing the metadata to make sure that is behaving properly, but it doesn't seem to stem from that. They play with HQPlayer, but that's not why I wanted to make the files.

 

Based on that display, by any chance the files are with 48k-base sampling rate (48k x512)? I'm surprised if such would confuse those applications so much, but that is one possibility and the 557DSD hints towards exactly that.

 

(48000*512)/44100=557

 

In addition to many DACs not supporting 48k-base DSD, could be that there is also software that doesn't.

Brilliant! Thanks! - that’s exactly what is happening. The errors were all with 48k based 512 DSD. I’ve just tried two 44.1k based files and they work perfectly with both Roon and Audirvana.
 

I’ll raise it on the Roon forum. Easy to work around, except of course it rules out using non-apodising filters with 48k based source files. 
 

The NativeDSD files must be limited to 44.1k-512 (even though they employ an apodising filter). Sensible decision.

There are couple of non-apodizing filters that can do conversion between rate families.. For example poly-sinc-xtr and poly-sinc-hb.

Thanks, I’d forgotten that. Actually one reason for exploring HQPlayer Pro was to try the effect of the two filters I can’t do in real time with HQP OS - sinc-L and closed-form-16M. I can try them with 44.1x files though.

Only if it allows you to do algorithms you cannot otherwise do, like DSD512 with EC modulators.

 

Output itself is the same you'd get from Desktop or Embedded.

 

 

 

 

@Miska surely the other benefit is not have your CPU running at high rates/temps creating noise?

One of the best upgrades you can make for hardly any money is to move your DAC/audio chain away from being directly connected to your PC.

Even just grabbing a $40 raspberry pi, putting ropieeeXL (which supports roon, DNLA, and HQPlayer NAA) on it and streaming to that rather than a local connection, makes a very nice difference for not much money at all.

Higher performance streamers are available of course but for the price hard to argue with a pi. And that way you'll get a better result no matter how busy/idle your PC is

Been there, done that! One box solution works better for me, only once you address clocks and power. Not to say never, as my next project will probably be dual CPU with HQPlayer desktop on 1 CPU and NAA on another. It never ends!!

Im looking to build a Roon core/HQP processing dedicated machine at the moment, but will definitely always use a good streamer for the endpoint.

Currently using the SMS200 Ultra which I just cannot get the same level of quality out of any actual direct-to-machine connection from.

I would look through music server builds thread. Things have moved alone very much since SMS200 Ultra.

If you use a NAA it becomes irrelevant. That's one of the points behind a NAA.

 

Otherwise it is very system dependent. For example I'm running the EVGA NuAudio card inside a powerful i7-8086K server running filters and ASDM7EC modulator and still the analog output is very clean (measured). It still depends on the PSU and motherboard too, and such. In this case running from a high power Seasonic Prime Titanium (TX) PSU.

I've been through the NAA route and much prefer single server, probably before the quality of the server. I would maybe agree if both my server and NAA were of similar quality, otherwise I don't see the point.

Just to add what I have said above, I have a NUC with separate OCXO clocks, main board and OCXO board powered by SJ DC3 LPS's, I have used this as for NAA. It doesn't sound as good as my Server. Nowhere as good. As I said above the NAA might sounds as good if the server and NAA where the same.

I have tried a few server and streamer options. Dedicated streamers were always better to my ears, and my two favourites were the pi2aes (if using i2s) and the SMS200 Ultra (with a good PSU).

I'm not sure what the argument for using a server rather than a streamer would be other than convenience. Certainly putting more powerful/noisy components in the endpoint would not be a GOOD idea.

Though my main dac has galvanic isolation on the USB and a PLL that attenuates jitter to a ridiculous degree. So the source device with my main dac in particular makes almost no difference. But on some other dacs I've got like the ADI-2 the source device can be a very noticeable change

NAA should be a low power device, the ones I use have Intel Atom CPU and consume around 5W or less power.

 

While most servers I have are high power devices consuming over 200W and PSU capacity ranging from 500 to 1000W. Another point is that it doesn't matter if it has loud cooling fans and such, since it can be located far from the listening room, in a basement or something.

 

For servers directly connected to DACs I use Gigabyte motherboards that have their DAC-UP USB ports.

I just downloaded 4.8 to try out the new Sinc-L filter. It sounds fantastic but now the converted files seem to have a few seconds of silence at the start of the track. I've not experienced this before. Is this intentional or is something wrong?

 

That is delay of the filter. Since the filter is about two seconds long.

 

If you convert an album instead of single files, you get the delay only at the beginning and at the end of the album, but at track transitions. If you convert individual tracks, then the delay is with each track.
