I suppose you don't use the above for DSD though.

DSD can only be used from USB Out.  There is no direct I2S PCI-E yet for DSD

If you are comfortable with DIY you can do that using Beaglebone Black v.C, Twistedpair Hermes, Cronus with clocks.  Pull the I2S stream straight into DAC.

Is that "version C" ?

Yes, I have been reading up on diyaudio about it.  I am going to attempt to do that with DSC 2.5.2 group buy.  It's worth trying.  Here are some links which I am still reading through but couple of folks on DSC threads have posted that they have successfully implemented the solution using the Botic driver.

Small update, I just finished testing new'ish Up Squared hardware with my bootable HQPlayer Embedded image. This fanless device works (for me) up to DSD256 upsampling using -2s filters. poly-sinc-xtr-2s with ASDM7 to DSD256 gives CPU load of 52% (this is probably quite on the edge though). PCM upsampling to 705.6/768k is safe and sound with filters like poly-sinc-xtr (20% CPU load) and closed-form-M (10% CPU load).

Building a new PC.Wondering what kind of motherboard people are using and recommendations ?

[PieterP]

I am building a hqplayer streamer now. I bought an asus rog strix x470-f gaming because of recommendations for the high quality bios and power supply (digi+ vrm).

[Miska]

I use Gigabyte Gaming ones with DAC-UP USB ports...

How important is memory speed when converting PCM to DSD ?

It is quite important, especially with bigger filters, so one with high clock speed and low CL is best. Also remember to check that you populate all memory channels of the CPU (2 on LGA1151 and 4 on LGA2011/LGA2066).

 

Even more important is amount of cache in the CPU.

I am a new member to CA, but have been a longtime user of HQPlayer.

 

I just wanted to let everyone know that a recent graphics card upgrade to a RTX 2080 has now allowed me (with my modest i7-6700k CPU) to use the full poly-sinc-xtr filter and upsample to DSD512 smoothly. This includes 44/16 files.

 

CPU load is around 65% (Roon + HQPlayer).

GPU load is around 75%.

 

The computer is running Windows 10, and the latest NVIDIA drivers are installed. HQPlayer is version 3.25.

 

I was previously using a GTX 1080 graphics card, and running HQPlayer like this was not even close to possible.

Thanks for that invaluable info. I have the same setup as you with the GTX 1080 and was wondering if one of the newer graphic cards would enable me to go to DSD 512 with the xtr filter. Now I know!

Yes, it really was a pleasant surprise.

Miska,

 

Can HQPlayer make use of more than one graphics card in the system?

Could you please try if you can upsample a DSD64 to DSD512 with poly-sinc-xtr filter?

Thanks.

Yes and no; there's no specific support for multiple cards, but if CUDA framework happens to give different GPU for different processing instances in HQPlayer, it should work. This is not clear from Nvidia's documentation and I have not tested it myself. In addition there are multiple aspects of multi-GPU. There can be cards that have more than one GPU on same board, there can be multiple independent cards, and there can be multiple cards connected to each other using SLI. And now with RTX series there's SLI replaced with NVLink...

 

I could implement specific support for multiple GPUs, instead of asking CUDA to give me a GPU... But that is for future.

DSD-to-DSD upsampling is always done using special algorithm and the filter selection doesn't have effect on that...

 

I also have RTX 2080 on order, but I have not received it yet...

Would RTX 2080 card have effect in this situation?

I've checked for you, and DSD64 to DSD512 with the poly-sinc-xtr filter works just fine with the RTX 2080 card.

To some extent yes, some of the process can be offloaded.

 

[gdpr]

My Pinkfaun 2.16 streamer has an AMD Ryzen 7 1700X CPU processor and no videocard.

OS is Audiolinux.

 

I can upsample DSD64 to DSD512 with poly-sinc-xtr filter.

 

I can upsample redbook to DSD512 with poly-sinc-xtr-2s filter, without any issue.

 

redbook to DSD256 with poly-sinc-xtr with a sporadic hickup, probably need to increase the buffer time to 100ms or so, now playing with 0ms)
