HQ Player

thanks Ted 👍

[Norton]

Is it still possible to download 3.25.6 (Linux Desktop)?  I have a license  and want to add HQP to a fresh install I’m doing on my PC.

 

Thanks N.

Jussi a question
Why with some songs the Apod counter remains at 0 and with others indicates very high numbers?
On PCM I use the PLY-SINC-GAUSS-LONG which is apodizing.

 

 

 

Some tracks are produced with problematic type of ADC / mastering tools. If the counter stays at 0, or figures like under 10, the source material doesn't require apodizing filter for correct reconstruction. High counts mean that you certainly should be using an apodizing filter to correctly reconstruct the source material.

 

Using apodizing filter for source material that has counter value 0, or very low, doesn't harm anything at all.

 

Only using non-apodizing filter for source material with >10 counter value means that you wouldn't have correct reconstruction because source material contains certain types of digital distortions.

 

Point of the counter is to indicate problematic source material.

Jussi, thanks for the explanation

You have max volume in settings set to -6 dBFS while enabling Direct SDM sets volume to about -3 dBFS. Hence you get the warning since your other setting exceeds your set maximum volume.

 

i have changed the max volume in settings to -3.0 dBFS and i am still getting this warning.

For my Susvara/Holo May I am currently using Roon Parametric EQ and then oversample to dsd256x ASDMEC7 with Sinc-L/Mx ... Love it to bits!

 

However, I was wondering if I use EQ/Convolution in HQplayer, instead of Roon EQ, would that yield even better results?

 

If so, which method in HQ player is prefered SQ wise?

 

And how can I translate my parametric EQ settings to HQplayer?

Depending on DAC, ASDM7 or ASDM5.

 

  

Which would you recommend for the Holo May, 5 or 7?  MANY THANKS!

Try 'em both, you decide.  I find modulators (and filters, for that matter) to often be personal choices, guided by system synergy and listening preferences.  Net/net, there is usually no "one good answer".

I have been but Jussi seemed to be quite definitive in the answer that I quoted and in the manual he makes reference to the choice being related to the DAC's reconstruction filter, so I was interested to learn which from that perspective is considered as the most appropriate for the Holo May ...

[ted_b]

Yes, I have the May, too.  :)

With 20 or 24 bits settings ?

This is clear.

 

What does puzzle me is what is triggers the apodizing count and what specifically is creating these issues in the music file in the first place?

 

I suspect this might be a complex topic, so if anyone has any links to any light reading relevant to this topic, that would be appreciated.

 

Just curious!

I use 20 bit as that is what those with measuring devices say the May is best at

It is the anti-alias decimation (down-sampling) filter used to convert high rate SDM to PCM inside the ADC chip. In some cases it is the production decimation (down-sampling) filter used to convert hires PCM to RedBook format. But in either case these produce errors in the source data and HQPlayer can detect this.

Yes, it is better to perform all DSP operations as one complete operation in HQPlayer.

 

If you have parametric EQ settings already somewhere, you can enter those parameters into HQPlayer's matrix processor. Syntax for it is documented in the manual. If you use for example REW for creating those, it is even simpler since you can export the settings into .txt file and then use that directly in the matrix settings.

ASDM7EC at DSD256 is good for Holo Audio DACs. Filter is up to your choice.

[GMG]

Does anyone here know to say which HQPlayer filters for PCM will be equivalent to the upsampling filters available within Roon?

[OzarkMtn]

@MiskaRecently received the Denafrips Pontus II DAC. Would you suggest ASDM7EC at DSD256 for the Pontus II? What DAC bits should the DAC be set at?

Thanks Jussi!

None, really...

Two "dumbass" questions for an early adopter of HQP, but a late adopter of version 4, as in today:

 

1) Understood that one could use V4 to play streaming sourced flies to get benefits of HQP magic.  Have Amazon HD app on Mac Mini but how do I "hook it up" so I can play Amazon HD streams using HQP?

 

2) Lots of new filters and other choice to make in setting that didn't exist on V3.  Using a Brooklyn+ fed by USB from a quad core Mac Mini, so what have folks liked in terms of set up?  Realize that it is personal and all, but since I have no idea what all this filtering, dither, modulators do or mean, in spite reading hear and in the manual, looking for a couple of starting points that folks have discovered sound good in their systems, particularly if they use a Brooklyn.

 

Thanks in advance for the assistance.

 

Thought of a #3 question (sound like the President, who relies on numbered responses):  Set up Client and a bunch of the artwork that is in the files, because it shows up in iTunes, didn't get posted.  What did I do wrong?

Reading your explanation, I am now curious to know which ADC chips produce such digital distortion and which do not. Can you please tell me?

You could use BlackHole or similar audio-loopback driver to loop audio outputs of other applications back into HQPlayer input.

For Brooklyn, you get best results using ASDM5EC modulator at DSD256 and filter of your choice.

These files play but don't show the cover images? Are the cover images inside the music files, or separate files in the folder?

Thanks Jussi!

The Pontus has no 1 bit hardware. Dsd is converted to 6 bit internally. 16bit to 1 bit to 6 bit are too many conversions. Just upsample pcm to 24 bit with dithering with your filter of choice. If you want to use a noise shaper instead of dithering, I would  set it to about 19 bit and use the highest sampling rate possible.

Based on specs it has 32-element analog FIR. Similar to my DSC1 DAC. It is not same as "converting to 6-bit"...

Don't mean to be a PITA...however @MiskaI appreciate your insights and thoughts. Any additional thoughts on how to get the best SQ out of this particular DAC?

 

Thanks @Hensemafor providing a response to my post.

 

I had HQPlayer out of the chain some of the time when swapping in some new gear and trying some different input methods, boy was it missed😔.

Thanks!
