I’m pretty sure you’ll only get DSD512 using ASIO driver on Windows with that DAC. Not with Linux RPi4 endpoint / NAA.
If you select “DoP / DSD over PCM” in HQPlayer, you should be able to get DSD256.
See DoP in my screenshot below.
Can you try that?
Thanks for chiming in!
Just check and my sdm pack is already on DoP.
Hmmm might be worth emailing the manufacturer about what DSD rates are supported on Linux.
Try using jussi’s kernel
@jussi_laako what is the command line control utility that doesn’t seem to be a thing anymore?
Sorry, didn’t quite understand the question…
There’s a link to a command line control utility at the bottom of the custom page that 404s
Ahh, source code for the control API and the command line utility. I had mistyped the updated file name, now corrected. Please refresh the page if needed.
Giving ext3 a listen for the first time, and it sounds like a softer sinc-s (the filter I was previously using heavily).
So far I like it. Very resolving is my first impression, yet musical. I’ll need to spend more time with it though.
It does give my little under powered machine (1.6GHz Celeron) a workout though. HQPlayer is currently using around 180% CPU doing 4x PCM LOL. I’ll be listening for drop outs at this point too, but it should be fine. Doesn’t handle Nx rates. Currently have ext3 set for 1x and Mx for Nx.
I really like sinc-Mx, maybe even more than ext3. I haven’t looked at any measurements of it yet, but it seems like a less harsh sinc-s, with better transients than sinc-M while still sounding “tall” from not rolling off the highs. From my less-than-figured-out measuring methods it seems like the passband is pretty similar between sinc-s and M, with the transition band width being the noticeable difference between the filters, as well as the amount of ringing. Sinc-s really doesn’t ring much at all, to the point where it can sound too clinical, and M, comparatively, rings almost constantly.
Mx, being a shorter sinc-M at 4x should be somewhere between sinc-s and sinc-m, and that’s how it sounds, and I think it’s a nice balance.
Two great new filters!
Things are so tight with my i7 7700 server upsampling to DSD256 using ASDM7EC that I cannot run ext3 with 48k 24 bit source files (eg: the new Black Keys album). I can do 44.1k 16 or 24 bit without a problem. Haven’t checked 48k 16 bit.
So I have reverted to ext2 for both 1x and Nx. I am still very happy with it.
I thought I did hear a difference using ext3 on 1x for Redbook, but it was not such a notable difference as to haunt my dreams with regret and make me consider a hardware upgrade.
The ext filter is one odd duck, and I’ve found it uses more processor than the xtr filters, but in a different way. The ext3 likes cores! The xtr doesn’t. Also I’ve noticed… with most of the other filters the higher sampling rate files use less processing power to get PCM to dsd256, but using ext3 it seems to want more and more as the sampling rates go up…
Are you able to get better results using the non EC? The ASDM7EC is a core killer!
I get stutter with EXT3 DSD256 7EC unfortunately. This is with a 9900K.
Works here with a 9900K and with a Zotac RTX 2070 SUPER AMP Extreme graphic card.
9900K usage is around 20%, but graphic card is around 90%.
There is no stuttering.
Hi Guys, have a question. I had been using HQPlayer 4 under Windows Server 2019 with intel nuc however its power not enough to process new ext3 and ASDM7ec especially case of Nx. So I thought that the new mac mini m1 will be a good choice, and yesterday did a try however PCM → DSD upscaling didn’t work for Nx.
It could do upscaling 44.1 to DSD64, however, didn’t work if I select 96 or 192/24 songs. Also, I’m using Roon as a separate server.
I tried different ways, like using my old nuc as an NAA and M1 as an HQPlayer desktop but the results were the same. My DAC is Ayre QB-9 DSD.
Kindly need support or suggestion, have a great day guys!
Tried with CUDA offload checked and it does seem to work now. 
Thanks for an answer man now it’s working however not for ext3 :(. I restarted the app after the config change. it’s frequently pausing the song every second.
Really? I havent updated my Antipodes CX for a good several months and its stating theres nothing to update. There have been a number of HQPlayer updates for desktop recently havent there?
Have Antipodes given up adding HQPlayer updates?
I can’t see anything wrong with your settings. You could try greying out adaptive output rate but I don’t think that will make a big difference to processor load.
We’re all finding out what the CPU/GPU requirements are for ext3. It seems to be quite demanding, particularly with the EC modulators and higher fx source material.
Thanks, Andrew, I just saw your message, so it’s a general issue then, we don’t know the ext3 process demand yet. Also, the stutter is an issue with ext3 even I select a non-EC emulator. However, I’m pretty sure that M1 is enough to process Ext3 and ASDM7ec.
I think of investing in a more powerful graphic card. This might be needed seeing Jussis direction with HQPlayer. Hope prices come down for the newest generation.
