Please, do try turning off the Air driver, and seeing what appears in your HQP settings. My setup is different, I use a MicroRendu between my server and the Dev, so what is seen is the mR, but please do try and see if the Dev is seen directly, without Air working.

 

That likely works around the issue, because it is totally different driver...

@Miska Would your HQPlayer OS image run and work on a 2011 Mac Mini?

 

I think it did last time I tested (I have one 2011 Mac Mini in storage). But Apple keyboard didn't work last time I checked. But OTOH, that is not very important detail, but just that you know in case it doesn't work for you either. Regular PC USB keyboard worked fine though.

Turning off the Air driver didn't work , I think it needs that to communicate.

I'll touch base with Devialet

Thanks

thanks Miska. I think it would work with the Yggy as that can only accept up to 24/192 anyway and due to that isn't a difficult upsampling load for the old i5.

Yeah, 192k and even more works fine on something like UP Gateway (Atom x5-Z8350).

I am used to enjoying convolution filters with roon (no HQP) 

I see HQP also has an option to use it, but I opened up the convolution settings and my God. It's complicated. It wants all sorts of things... I only have a zipped up file... How do I do this?

If you get some notable differences, then there is something wrong in your test setup.

 

LOL.

 

Jussi refuses to entertain the "A novel way to massively improve the SQ..." invasion.

 

The man is consistent. You must respect that. He posted similar in that other thread too.

Haha

 

What is in the zip file? 

 

32-bit (or 64) floating point mono WAV files? That's what HQP needs.

 

If you share exactly what you have and how you made those it can be easier to help get into HQP

 

Without that info, can be hard to help

I got a better idea. As the files I have are just *ok* as I jsut started using convolution files. 

Do you know of a source that I can try many types to see which I like? And use with hqp

Does Roon do anything to the file or the stream before it hands it to HQplayer?

 

Depends on your settings. But at least it is decoded. So you can play MP3, AAC or what ever Roon supports, but HQPlayer doesn't.

 

Your reply implies that there are some instances where Roon passes through the file completely untouched but I wasn't aware of that. That is part of the reason why I have stopped using Roon and instead use HQPDcontrol to play my locally stored files through HQ Player. Does Roon ever 'pass through' files without altering them in any way?

All the formats work fine here, but you could enable and check HQPlayer log to see why it is not working.

Here the log after the scan of ext4 formatted hdd.

HQPlayer Embedded 4.21.0 on Ubuntu 20.04.1 LTS

As reported there are just flac files on the hdd but they are not viewable in the library

Depends if you consider decoding as altering. But bare undecoded files, never.

However, there is a SQ difference when using HQP alone or via Roon!
without using any Roon settings.
it's tiny, but I prefer HQP alone.

Miska,

 

re reports that one line of code change between versions has different sounding output. Could it be the compiler introduced more changes to the binaries (perhaps some optimisation) than expected? Expanding the two install exe's and binary file compare would reveal that?

Unlikely, since it is not in the relevant code path.

 

In any case, that would be out of my control and irrelevant anyway for NAA output.

@MiskaIs it possible to configure HQP to upsample 44.1 kHz only? How?

No, it is not...

For PCM > PCM, wouldn't setting:

• Filter 1x to desired filter, say sinc-L, and
• Filter Nx to None

achieve this?

 

Ok, this will not work if you want to exclude 48 kHz, but I'm guessing the poster meant 1FS inputs.

@Miska ....

[CheapSplurge]

Spectrum visualizer in roon/hqplayer just to see which FR range is jumpy?

Looks OK, if some files are missing, they are not found for some reason, or access permission for "hqplayer" user is missing.

On a related subject, I was wondering @miska, if you could introduce the possibility of choosing different output sampling bit rate/limits, depending on the original sample rate?

 

For example, lets say a system can only cope with sinc-L for 44.1 original material at a limit of 44.1x128. So for Nx you choose poly-sinc-mqa-mp; but you don't want Nx material limited to 44.1x128, since with poly-sinc-mqa-mp you can go at least 44.1x256.

I've said earlier that I don't want any rate tables, because there's no limited set of rates. And it adds a lot of configuration and testing complexity. Many people already complain that the settings are complex. I want to be very careful introducing new settings.

I went back to 4.9.2 yesterday. It still sounds amazing to me.

 

That said, I also took some time to use REW to create convolution files which I've loaded into HQP now as well. I find the difference to be pretty subtle, but quite effective for the limited time I've been able to listen so far. I'm not sure if the image depth and space should be changing as a result but I do feel like even more than before, sounds in the soundstage hang and float more convincingly than before, and it was already something I was quite happy with. Bass, too, is more refined and taut. And given the actual vs predicted lines in REW, it didn't make massive changes to anything, but it did smooth response somewhat.

 

I saved my .wav files with the highest sampling rate REW allows and saved them as mono files, one each for left and right, and 32-bit. HQPlayer never complained when I loaded them, so I assume I did that right? I convert everything to SDM output, if that matters.

 

Thanks again @Miska for this amazing software.

 

I also gave the built-in Roon upsampler a go yesterday. I was using Smooth, MP and 7th order CLANS noise shaping, DSD512. It worked my Ryzen 3900x pretty well on my Core PC but it played without a hitch. And I did like it - just not quite as much as HQP. Another buddy tried the same experiment yesterday and also found the same result. Roon is pretty good, HQP is just better, more refined, more transparent and resolving.
