HQ Player

[jvvita]

Hey guys, I am writing to get some advice.

 

I have been using Hqplayer with servercore 2016 and AO. I am using a gigabyte Brix, with an i7 6500U and 16gb of ram. Down the signal chain I have an iFi iPower (acting as an USB regen) and finally a PsAudio DirectStream DAC. The music is stored in an Asustor NAS.

 

Despite the i7, the computer stutters when upsamling to more than DSD64, using poly-sync xtr mp and ASDM7. I can go no further. Reading other posts, my specs seem to indicate that I would be able to at least go to DSD 128. Changing the audio chain doesn't seem to solve the problem.

 

Also, even when at DSD64, I often hear some "plics" and "plocs". The volume control of Hqplayer is limited to -5 dBFS. 

 

Appreciate your insights.

This is only a dual-core CPU, likely it doesn't have enough processing power with xtr filter. But you could use xtr-2s variant instead for lighter CPU load. It is at least worth testing that way to see.

Ok. Gonna give it a go. Let you know 

[jvvita]

Could you please explain what does fifth or seventh order mean? Always been curious and never able to find an explanation for this characteristic of the filters

[jvvita]

My experience with PS Audio DS Dac is that better results comes sending PCM 176 (from 44.1khz sources) or 192 (from 48khz sources).

 

The bass extension is better, and the sound has more weight.

Thanks for this.  Jussi, is it possible to set the PCM side of HQP to automatically  make 44.1 sources into 176, and 48khz into 192?  Or must one manually change the setting?

And don't forget to upgrade to Snowmass. Ted has worked his magic once again. Huge difference.

Hey gays,

 

is anyone using HAF filters with HQPlayer?

 

Their proposal seems interesting, just wandering if anyone has real life experience with them.

Have you seen this thread?

 

 

No, I did not know it. Thanks for pointing that out to me.

[jvvita]

Guys, 

 

a 4.0 license, upgraded from a 3.x, will allow to install HQP on how many different computers?

[jvvita]

Hello, sorry if this has been asked before. I just wanted to know if HQPlayer 4 license will allow more than one windows install.

[jvvita]

Thanks. As I understand, it is working liking Roon. You can move the license for one computer at a time. This would be sufficient for me (I don't need to computers running simultaneously). 

[jvvita]

If I understand it correctly, linux is performing better than windows with 4.14. But should there be any difference on performance on running hqplayer desktop on Ubuntu 21 and running hqplayer embedded bootable image?

[jvvita]

Thanks. Ubuntu 20 does not recognize my network card. It works flawlessly on 21

which NIC are you using?

Realtek 2.5G. That comes with the Asus Z-590 Prime.

Note that you can install Canonical's "hwe" (HardWare Enablement) kernel branch which keeps you on their latest short term kernel on an LTS system. Sometimes the installer of later point releases do this automagically.

 

Don't really know how to do it

It will then stay up to date with system updates.

Thank you so very much. But now I have to figure out a way to install the kernel without network access...

For such cases I have a simple cheap gigabit USB-Ethernet dongle with old enough chip. I can then plug it in to have internet access in such cases.

 

Success. Found an old wifi dongle that did the job.

 

Now for the good news: not only asdm7ecv2 is possible, but also two filters that would not run in windows (poly ext3 and gauss xla) now work without hiccups (all to dsd256), even with 7ecv2. 

 

But I had to manually enable Intel turbo boost in Ubuntu. 

 

Does hqplayerOS enable turbo boost by default? Running Intel i9-10900k

[jvvita]

Does the limit counter increases when the volume button goes red? Did you try setting the volume to -3db?

This is the key. You can determine speed of the transient by it's spectral spread. Just like square wave is infinite sum of odd harmonics of it's base frequency. If the transient's harmonic series doesn't contain these high frequencies, it tells that it is "slow" or "soft".

But for Redbook these "fast" transients would be irrelevant and would not be in the recording, being the signal band limited to 22khz, right?

Wouldn’t be irrelevant. Filtering could  reflect images back into audible range (though at low levels). I wouldn’t be surprised if Miska would advise apodizing filters for these cases, but Miska’s of course the person who actually knows (unlike me 🙂).

That is precisely my point. You would have to low pass at 22khz. Anything above that would not be in the recording.

Thx, no, not yet, is it this one?

https://www.realvnc.com/de/connect/download/viewer/macos/

Completely free?

It is completely free. But Mac-to-Mac you don’t need it. All it takes is put on safari address bar VNC://IP OF REMOTE COMPUTER. then click on start screen sharing and that’s it.

Thx mate!

I am feeling like I am starting with computers though I was using macs for some time but never though about such features before going for headless servers.

Plus I ve been wondering about the lack of native Apple out-of-the-box solution besides an Apple Remote Desktop app costing 80 bucks in App store.

So regardless of this URL being called "VNC..." I won't need the before discussed VNC client-/server software from realvnc.com, right?

Like Jussi said, you need no other software. Should you have trouble getting everything going, drop a note

P.S. Annoying sibilance is many times solved by choosing more suitable upsampling filter. Rather than with EQ.

Could you please elaborate a bit more, on how does a well-constructed digital filter may affect sibilance?

Thanks.  I figured as much.  My plan is to get a SBC, but what I want is not available.

Did you consider a ubuntu server install, with only naa pkg running? You could install and then boot the server from USB. A bit longer boot time, but it would work

I'd consider anything, but it's been many years since I played with Linux.  I don't remember hardly anything.  I'm a 53 year old computer geek, so I guess could figure it out.  I know there are lots of people to help.  For now, Jussi's bootable USB sticks are working, but I admit if this all works out, I'd like to do something sexier than a USB boot.  Not that it's a big deal, it might just be nicer in the long run.  And the stick doesn't have to be there sticking out.

 

Boot times don't bother me, but I do intend to leave the NAA on 24/7.

It will be super easy. Ubuntu server installer got so much friendlier nowadays. You just need a computer and 2 sticks: one with the installer, and one to be the installation target. I have done this quite a number of times. Should you feel adventurous or need any help, just drop a note

Just wanted to find out in the current state of HQPlayer Embedded.

The latest jl+ kernel's for focal did not worked for my friend's Intel and broke my AMD 5600X (5.15.39) yesterday, I could not use the keyboard at all after installing it and it was reporting an error at boot. To save time I went ahead and:

• Installed jammy minimal from scratch
• Installed hqplayerd 4.32.1-135avx2

 

It is working on my 5600X with no issues, I did not need to modify anything in jammy at all, just installed libgmpris 2.2.1-10

 

My questions:

 

1. Building from scratch for Intel 11th Gen 11600K and AMD 5600X which versions of Ubuntu and hqplayerd are recommended for each (noticed there is no amd_amd versions)
2. If using HQPOS could I mount internal SSD's with it and possibly NFS server ? need to rebuild my friend's HQPlayer server.
3. Anything you would recommend @Miska, maybe I should check if you HQPLayer OS includes now Wireless Drivers or Realtek ones?

Thank you

 

 

 

 

Hello, just a quick question: in you fresh ubuntu server, did you install low-latency kernel, or only hpqlayerd + libgmpris?
