    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...

    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.

    This is also reflected in the manual / help page table genre suggestions... :wink:

    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...

    A bit of aliasing from above 44.1 kHz. And a bit of SMPS/CRT whine at 29 kHz.

    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...

    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.

    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.

    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...

    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...

    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...

    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...

    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.

    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...

    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...
