HQ Player

[ted_b]

Filters are used when PCM is upsampled (either to higher PCM or to DSD). If you remodulate, say, DSD64 to DSD128 then the modulator is used but not the filters. Stay away from the DSD settings for now (leave them at default) until you get a handle on the other stuff. The anodizing counter is pre-filter and just an FYI that those tracks need apodizing filters (checked in pdf filter list)

Thanks for the replies i just noticed when playing 44.1tracks an Asio warning in the bottom left hand corner about  sample rate mismatch 352800 vs 5644800 is this any thing to be concerned about or is it just for informational purposes only?

the high frequency crackling noise for the first ~2 seconds at the start of playback i mentioned in my earlier post is only there when i enable direct SDM

Yes, I'll look into it. I think I need to move the place where the gain is applied to earlier place.

 

great - thank you!

 

Just to make sure I was able to outline the issue correctly...: based on my user experience my understanding is the place where the gain is applied should be later, not earlier ... so that the Auto gain is first applied when the respective subsequent track starts to play.

Anway - thanks again!

just a correction the cracking noise is also on foobar when using the DSD processor but also only for 1~2 seconds at the initial start of playback of an album and every album after but only the start not between individual tracks.

i would like to play my cd rips in DSD128, my hi res(varying bit depths(16-32) and sample rates(48-384)) downloads in DSD128 and all DSD to DSD128

If you want to upsample your DSD64 to DSD128, you'll need to disable Direct SDM.

yes i have worked that part out now, but as i only have DSD64 as SACD ISO's which are not compatible with hq Player that is not a problem atm and i will just use foobar for sacd's and any DSD up and downing until i decide if i should purchase hplayer. There is not really a one stop solution with hq player, although the sound quality is fantastic. In foobar i can choose the behavior of the re-sampler for each and every sample rate, that would be a great addition for hq player.

Hi Miska, 
I have tested the new version but I still have a question about the much larger number of threads than in version 4.10.
At startup, there are almost 100 more threads than in version 4.10 (230 vs 110).
Normal, there are more options (like the APO counter) but if I play with the HQP client and change the filter (for example.), then the number of threads increases to 300. 600... 800, etc ... with each change via HQP client.
They seem to be inactive ... but don't disappear without restarting the program ...
There is no possibility of purging (semaphore system ?).

Thread is waiting for:
Handle 0xfad8 (Semaphore): (unnamed object)

It doesn't seem to have any SQ impact, but my system runs with less than 600 threads in total, so when the number of threads exceeds 2000, I panic ! 😋

@Miska Thanks !!
The latest version seems to fix the problem... after 3 hours of listening and changing filters via HQP Client, the thread count is still 229!
Not 350, 600 or more with ghost threads!

There is almost unlimited number of possible sample rates. So it is kind of pointless option. So you rather have option to choose resampler for hires vs regular content.

That is earlier, at the point when tail of the previous track is still on the way out.

i have another question i was resampling 44.1x 16bit to DSD128 and it worked well for hours then one album(44.1x 16bit) had a track that would cut in and out when i changed to another filter it played fine is this something that can happen(and why) or am i just lucky?

Some filters are much more demanding than others so this is not surprising. This usually shows up when doing PCM to DSD and is an indication that the problem filter is asking more than the CPU can handle. There are some filters that will not work without a GPU assist when doing PCM to DSD at DSD 256 using EC modulators.

even when it worked fine for hours? That brings up another point i have a Nvidia GTX960 4GB graphics card and even though i have gpu offload enabled i don't see the GPU doing any work and CPU is @ 40%

The GPU is likely not fast enough to be of any help and/or the drivers are not current enough to work with HQP. Jussi has said that the 20 and 30 series NVIDIA cards are the ones that will work best. The sudden drop out problem can be caused when everything is on the edge but working and then the OS timer kicks in some housekeeping chore or checks for an update or some other process becomes active and pushes it over the edge. These kinds of problems are why lots of folks here have gone to Linux based systems. I used to have this issue with my old Win 10 system but since switching to a Mac Mini M1, I no longer have any drop outs unless I try a a filter that pushes too hard but now I know what works on the M1 and what does not. This stuff is just maddening sometimes.

ah... now I've got it. Makes Sense!

Thanks 🙂

@Miska  Just in case, if I decide to change my DAC (RME Adi-2), a challenger under $2000 ? 😉

I have a question regarding the checked Direct SDM function in DSD source settings in Version 4.12. I frequently leave it checked (without the added 6db) for several reasons among which I don't use the HQPlayer volume control as I don't need it. The checked SDM setting compensates for the needed -3db by itself. My question is in regard to the warning message that constantly pops up regarding volume level. I do understand the purpose for that but in my case I am well aware of the result of this setting I've been using it since well into version 3. Also my previous volume setting was not lower than the resultant checked SDM. How do I get that message to stop popping up? I simply don't need the constant warning regarding volume.

 

Yes I have a preamp and several different amps that I use so I know what to expect with HQPlayer volume off. Any advice on  how to get rid of that message? I do play a mixture of redbook and dsd files so the HQPlayer volume control has no use for me.

What is your volume range setting in HQPlayer Settings-dialog?

I also use an analog volume with HQPlayer and my range is -3dB Min to -3dB to Max, am I right?

-60 to -3db I thought that was a non issue when SDM is checked. At that setting the volume control is dissabled. I look forward to your advice. I'm using HQPlayer in Linux but I doubt that affects this issue.

 

What is your volume range setting in HQPlayer Settings-dialog?

 

 

[Miska]

Volume is capped to the specified range, and Direct SDM specifies certain fixed volume value close to -3 dBFS, so these two may cause conflict and you get notified for that reason.

 

[Mark Labbett]

so what values should i put into the settings panel for the volume so as not to get the constant warning?

Same question. What values can I put to eliminate the warning? 

[Mark Labbett]

i am also still waiting for an answer regarding another warning/notification regarding sample rate mismatch in bottom left hand corner of the border and weather or not it is just a FYI or if it is something that needs to be fixed, hq player is a great sounding piece of software but i seem to be spending way to much time worrying about settings as opposed to listening to music lol
