RAM speed does matter for number of algorithms, since the data doesn't always fit in CPU caches, and then RAM speed becomes critical.- jlaako

My 13900T can do DSD1024 with default filters and ASDM7EC-light. I have also RTX2080 on that one, and the combination can run DAC corrections at DSD512 for T+A DAC 200. Maybe one important aspect is DDR5-6400 CL32 RAM (G.Skill). HQPlayer Embedded on Fedora 39.- jlaako

If you are using HQPlayer to run Wandla, run it at 705.6/768k PCM and the built-in filters get bypassed. Or you could run it at DSD256 or DSD512 for example (using ASDM5EC-ul/light/super modulator).- jlaako

Yes it works fine without DoP. Except of course on macOS. Which OS are you using? If you are using Windows, especially if you are using Roon as HQPlayer front-end, remember to disable Wandla from Roon Settings -> Audio. Otherwise both applications will try to access the ASIO driver at the same...- jlaako

Limited counter can also increment for other reasons, so it is not just simple function of the output level. It is more of indication that bad output has been detected and action taken based on that. So it is more elaborate than just level indication.- jlaako

It is normal that you would have more pipelines than you have output channels. Or input channels. People using HAF filters or certain cross-feed configurations for example need four for stereo. If you want to do 5.1 channel to stereo mixdown, you need six. Different matrix profiles may use...- jlaako

It should now work better with NAA v5... I believe Red OS is still on NAA v4 component. But you could have another microSD card with NAA OS.- jlaako

On of the good ways to see effect of particular band limiting on a single transient. Every band limiting method will affect it in a different way. I was demonstrating this some 10+ years (or maybe almost 20?) ago with a recording I did myself. It is good to switch Audacity into dB vertical...- jlaako

It is less likely to have effect on that when the counter stays zero. The counter is not absolute, it has quite a bit of safety margin to avoid misdetections and such. This is the case yes. Although your DAC side will also ring in case of digital clipping, even if the source signal didn't...- jlaako

If there is wireless on the path, then it is beneficial. For pure Ethernet it may help in some cases, but I don't expect so much difference. The protocol is somewhat different now though. Also to support the new features it has.- jlaako

Great! If you are using WiFi, the new NAA v5 protocol may be beneficial compared to the older v4 one. NAA OS provides v5 while I believe Red OS provides v4. I don't know what RopieeeXL provides. This mostly as heads up in case you encounter dropouts or something like that.- jlaako

First thing to check is that firewall is not blocking the traffic, and that you have only one network interface active (Control Panel -> Network connections -> Manage network connections). Main reason for not finding a NAA is that outbound multicast packets end up on wrong interface. They should...- jlaako

Practically yes. And so does ADC decimation filter, so the ringing gets baked into the source data already. With apodizing filters you can replace/reduce the ringing with less disturbing and possibly shorter one. Solution is to keep high enough sampling rate throughout, and that's what you get...- jlaako

What looks like "perfect" filter (if we talk about steepness) from frequency domain point of view is absolutely opposite from time domain point of view. Because these are related through inverse 1/x relationship. Likewise, in mathematically related aspect, when you do spectrogram with FFT (like...- jlaako

HQPlayer has supported DSD2048 for several years. Just DAC has been missing. And I'm not sure if such would provide any improvements. USB Audio Class is not really fit for the purpose though. DSD1024 is already exceeding the specs. So it would need network interface, or using custom USB...- jlaako

And only wide filter setting. Because narrow turns it into distortion generator. But with the correct settings it also measures much better in DSD256 than it does with PCM input or any other settings.- jlaako

Yes, that is pretty unused overall, so it was good choice for the purpose. Some may be, but many of those are just bugs in AK4191. Or poor documentation from their side (which at least seems to be the case). Now it is just like ESS chips, which have always been like that. Yeah, partially due...- jlaako

You mean AK4191? I have Gustard A26 for example. And SMSL DL300. After Gustard fixed the A26 firmware so that DSD Direct works correctly, it is pretty nice DAC, especially through ASDM7EC-light modulator at DSD256. I also have SMSL M400. But the earlier AK4490/AK4493 work really nice in DSD...- jlaako

At one point I had such experimental one, using 8-bit data format (U8). And technically HQPlayer can support such any day. But it is not necessarily any better, because you immediately introduce some problems familiar from PCM. We can actually do better with 1-bit streams than multi-bit, as...- jlaako

Yes, many times if you have apodizing counter incrementing you would also have filter ringing in such cases. But apodizing counter focuses on other aspects though than filter ringing, since we are assuming you have a sensible non-ringing filter (analysis runs purely on the source data). IOW, if...- jlaako
