HQ Player

[jimdukey]

I used to be, but it was boring.

Newbie is OK, considering my advanced age...

When does one move from Newbie to Sophomore?

I have more posts than some Sophomores!

I think I'm Ready.

You have to pass your final exams...

But in the meantime we will still engage with you, even though you are a lowly Newbie...?

Perhaps therein lies the explanation for not progressing beyond Newbie.

What took you so long?

something i don't understand   PCM44 to DSD512  using polysync filter  take 2minutes to initialyse and then take  37% of the CPU

and  PCM44 to DSD256 using Polysinc XTR start in 2s and take 45% of the CPu ?

Different filter, different initialization algorithm... Also the conversion ratio is different which also has impact on initialization time. This is totally different from the amount of CPU time it takes when running the filter.

 

2 minutes sound like quite long time, what kind of CPU do you have?

 

[juanitox]

it feels like 2 minutes , don't know exactly ?     i have a I7 6700K no  Video card   ,too slow for XTR in 512  but  fortunatly DSD256 with poly XTR  sounds  incredible with HQ 3.21   better than polysync DSD512

I gather the new Ifi Idsd Pro Dac uses USB 3.0.

Does that mean I'd need a new Computer ( IMac ) too?

Mine is a few years old, High Sierra, USB 2.0

I have the ultra Rendu into the usb dac of an Oppo 205. Running Roon and HQ player.

This morning I upgraded the firmware of the player , also the dac input, and now all I get is white noise when using the HQ player through Roon. Without HQPlayer in the loop (using the OPPO as playback devise) I get the music.

 

Any idea what happened or how to get it working again?

 

Thanks,

 

George

Are you sending DSD to the DAC in both cases?

 

[acousticmood]

When running out to the ultra Rendu direct from Roon it only works with sample rate conversion turned off. When it is enabled (either dsd or pcm) I hear the music but with what sounds like digital distortion- the tempo also slows down a bit, that sounds like a clue but I have none.

thanks

That happens to me on first attempt to use HQ in a given day. ( Distorted, slows down ).

It doesn't always happen, but still....

Anyway, just stop playback, and press play again.

That Always fixes it for me.

I only have USB or Firewire into Dacs, no Streaming.

I've sometimes seen that on macOS, rarely, but a few times. macOS having some hiccup. Stop/Play cycle fixes... It is rare enough that I'm not sure whether it happens with local and/or remote media (Roon or NAS). So whether it could be something related to source, something related to CPU or something related to CoreAudio.

 

Never seen such on Linux or Windows.

To be clear - I get white noise when I play Roon with  HQ. I get the distortion when not using HQ and playing Roon to the ultra Rendu, with sample rate conversion enabled. When sample rate conversion is disabled the music plays fine.

 

None of this surfaced until i upgraded the OPPO dac.

Maybe they have disabled or changed the DSD support on firmware upgrade?

Hi, just curious as I have a similar problem using Ron, HQplayer, STi5, uR and a Qutest. The white noise comes just from one channel? At every time?

[acousticmood]

Both channels evert time

 

[acousticmood]

Yea it seems like it is an OPPO issue, since Roon without HQP also doesn’t work with sample rate conversion enabled.

 

im working through it with them now.

Thanks. No sure if this helps but try not to change the tracks when they are playing. In my system it works. Also when it starts, go immediatly to uR and within tge apps menu, choose another option and then revert to HQplayer. It always start without whyte noise. Cheers

I have a question regarding the best way to use the HQPlayer volume control to provide appropriate headroom to avoid clipping when running room correction convolutions in Roon.

 

There are three ways I can do this:

 

1) Keep HQPlayer set on maximum volume, and reduce the gain in Roon's headroom management to the point that clipping is no longer indicated in HQPlayer.

 

2) Disable Roon's headroom management, and reduce the volume in HQPlayer to the point that clipping is no longer indicated in HQPlayer.

 

3) Share the headroom management between Roon and HQPlayer.  So if I need a total  -6dB reduction, set Roon's headroom management to -3dB, and HQPlayer's volume control to -3dB, giving -6dB overall.

 

From a technical perspective, which of the above is the optimum solution?  Any ideas?

(2), just send bit-perfect data from Roon to HQPlayer...

Ah, but it is not bit-perfect data in Roon?  Note that I am running the Room correction convolutions in Roon, so does this advice still stand?

Then you should run those in HQPlayer instead so that Roon becomes bit-perfect...

It would be helpful if the HQP interface was more user friendly.  I utilize Roon's headroom management because its so easy to implement.

 

HQP sounds great, but the interface is antiquated at this point....
