HQ Player

I am sorry, Jussi, but now I am even more confused. I must be missing something, but I don't understand what is new about this feature. I have always been able to choose between "Time", "Remain", and "Total Remain" in the upper right corner of the HQPlayer interface on my desktop.

 

It was requested feature, now remote control applications (hqp-control and others) can change that mode remotely and get the corresponding times from HQPlayer. They can also figure out what is the currently selected mode if it gets changed. Previously this wasn't exposed through the control API.

What is hqp-control that you refer to? I see hqp-control.exe (189KB) in the program folder for HQPlayer, but I don't know what it does and clicking on it just causes a brief flash on the screen.

 

It is a command line utility to remotely control HQPlayer and comes with HQPlayer Desktop. It is also available as source code and it is the client side reference code for HQPlayer's control API. Roon, HQPDcontrol, Alchemy, Muso and Geoff's Kodi and JRiver bindings use this control API to control HQPlayer.

Many thanks for this thorough explanation.

… and thanks very much for adding the time feature Miska. It’s very much appreciated!

Dear support:

I just upgraded my HQPlayer from version 3.21 to version 3.24, but now I am having an error "Cannot start because qwave.dll is missing". I uninstalled and reinstalled but error persists. Any advice?

strange, in French we have cf too, and coming from the same latin locution conferre but the meaning is more "go see and check"

 

poly sinc definitely makes sense with hires ; can't tell about ext2 and n48 hires

 

I wish I could understand the theoretical differences between polysinc and ext2 better. I was hoping Missa would comment in relation to hires files to DSD512 to the T&A8.

 

Re- cf:

From Wikipedia, the free encyclopedia

 

The abbreviation cf. (short for the Latin: confer/conferatur, both meaning "compare")^[1] is used in writing to refer the reader to other material to make a comparison with the topic being discussed. It is used to form a contrast, for example: "Abbott (2010) found supportive results in her memory experiment, unlike those of previous work (cf. Zeller & Williams, 2007)."^[2] It is recommended that "cf." be used only to suggest a comparison, and the word "see" be used to point to a source of information.^[3][4]

You are spot on!

ext 2 really caught me off guard! 

The combination of the updated DSD5 modulator and ext 2, is the best sound I ever got!

Cheers, @Miska

 

What are you upsampling to, and with which DAC?

[shahed99]

This might be slight off topic, but regarding convolution on HQPlayer. In the past, I've been using T+A DAC8 DSD dac upsampled everything to DSD 512 through HQPlayer. However, earlier this year in order to simplify my system and deal with a difficult room situation, I switched to all-in-ony Lyngdorf TDAI 2170 with room correction. It works extremely well. However, Lyngdorf only supports DSD 128 and converts everything internally to 24/96. Not sure why it upsampled DSD 128 through HQP still sounds so much better.

 

I'm currently considering switching back to upsample DSD 512. But room correction is something I'd want. Any HQP user has good success with room correction while upsampling to DSD 512? How much pressure it puts on CPU? What is the best room correction software to use with HQPlayer that is easy/simple to use and is as good as Lyngdorf that doesn't suffer dynamics/sucks the life out of music. Is there any good instruction out there to use room correction software to use with HQPlayer?

you need to enable the QWave service.  What Windows OS are you using?

[Rafi]

I am using window server 2012 r2

Ok, go into command prompt, type PS to enable powershell.  Install qwave by typing command:

 

Install-WindowsFeature -name qWave

Since convolution in HQPlayer is processed at source rate (except for DSD-to-PCM where it is done after PCM conversion), the load mostly depends on format of the source material. For RedBook PCM, it is usually not heavy at all, for DSD-to-DSD it is really heavy.

 

In order of ease of use, correction filter tools probably go in this order:

1) Room Eq Wizard

2) Audiolense

3) Acourate

4) DRC

 

Acourate being the most powerful tool and Audiolense XO being second. Room Eq Wizard can be complemented with rePhase for more advanced filter generation.

DSD 128 with the Lampizator Euforia. Mostly RB material. 

Lampizator likes 5th order filters in general but the said modulator/ filter combo was a real "wow" moment for me...

[Whitigir]

I am trying 768KHz in Windows 10-64bit.  It doesn’t seem to work ?

[jimdukey]

Same for me, DSD 128/Euforia.

 I also like the Ext2 Filter, and just tried the ASDM5 Modulator, and am preferring it to the ASDM7 I was using.

Even tho the DSD 5 was updated, Jussi said something to the effect that ASDM7 was more modern, I don't know exactly what he meant, but that ASDM7 was preferable.

So I tried the ASDM5, and am liking it!

ASDM7 seemed to have more separation of sounds, ASDM5 a more complete, blended whole.

Yes, I'm going New Age on this!

Of course it may be wrong...

What DAC/driver/backend are you using?

I wish it too.

trying to make some theoretical sense of my readings, I wished mqa would win my 192 shoutout and thus have ext2, long, for 44.1; sinc, middle, for 96, and mqa, short, for 192 source files.

Unfortunately xtr2s, very long, won....

I could physically feel mqa go deeper down but preferred the tighter firmer more precise presentation of xtr

Using Ibasso Dx200 WaSaPi.  

[Hoang Anh]

I want to ask for experience. Since I knew USb audio transmit do not error check and correct like copy file, and highest data rate  may result in more error, upsampling DSD to get good result need better connect. Has anyone try seperate USB card (instead on  motherboard on), good USB cable to get better result.

There are other factors (analog domain) in USB that matter more, for those reasons USB ports matter. Be careful with audiophile data cables, many are not compliant with the specification and none (?) are certified. So often a HiSpeed, or SuperSpeed if the DAC has USB3 connector, certified standard cables are good choice - look for the certification label. Transfer is practically error free and you will very likely hear clear pop/crack (like dust on vinyl) if there are any errors.

Please go to Windows Control Panel -> Sound and then to properties of your DAC. From there to the Advanced-tab and see what formats are listed for the Default Format. These are the ones available from the WASAPI driver.

 

Here's an example from a TEAC DAC:

 

 

Does your DAC come with ASIO driver too? If it does, it may be good idea to try that one.

 

[Volodymyr]

folks, can anyone advise if any comparisons were done for MPD vs HQP sound qulaity?  Any impressions?  Particularly PCM is interesting?

Thank you, I will try it out with this.  I think WASAPI is maxed out at 384khz.  I tried ASIO, but it only does upto 192Khz ?

[Le Concombre Masqué]

@Miska

 

Could we please get a ext2 filter that outputs to another DSD rate family (that is n48 to n128 only of DACs such as the TEAC)?

 

I guess that I would not be the only one pleased, ext2 becoming popular.

 

I'm back to xtr2s for 192 and 96 so I guess I favour tightness and precision ; to my ears ext2 has the pros of xtr2s while being less prone to a certain "verdeur" (harsh would be too strong a word, and even hard but...)

My bad, I got messed up.

 

i used ASIO and it does upto 384.  When I picked 768, there was no sound playing.

 

Wasapi is stuck at 192Khz max

I have been looking at the DX200 - I like having a fit for purpose device (i.e a DAP instead of a phone with an external DAC/AMP) and also like being able to also use as a good DAC.  Have you tried the DAC at DSD 512 with the ASIO drivers?
