HQ Player


Recommended Posts

@Miska I've tested the CIC integrator. From DSD64/128/256 to DSD512, no stutter anymore. Thanks for the effort.

 

Do you also optmise the FIR integrator? I remember last time this FIR was also a bit unstable and caused stutter from time to time.

It has always been optimized...

Great. Now all integrators work well. Thanks again.

@Miska is the new poly-sinc- ext2 a less CPU demanding version of poly-sinc- ext or is it a completely different filter, I’m not 100% sure from the new manual. 

 

It is entirely different filter, but designed for similar goals. So they share some of the design parameters.

What at is the relevance of the Nyquist cut off?

 

That it is not a "half-band" filter that are otherwise common these days. Particularly it doesn't let any image band around Nyquist frequency (22.05 kHz for RedBook).

Thank you. I'm certain one can spend fortunes in tweaks, cables, DACs and not get the tangible improvements you offer.

 

As of CIC integrator, that I picked as  my favorite last week : DSD 64 to 128 now works with convolution engine SAVE.Tried to convince myself ADD has more snap but I'm definitely more comfortable with the organic feeling conveyed by SAVE. At least with my Bowie's Ziggy SACD rip, the one source I tried today.

 

As of Sinc M : to SDM worked only with 44 here today ; might appeal to minringFIR aficionados, a damper afaik, based on one track : Pepe Romero (K2HD sampler)

 

As of ext2 to SDM worked only with 44 here today ; should be considered by aficionados of poly sinc xtr 2s. Loved it on Pepe Romero. hand claps and foot stomping might have less impact than with xtr but guitar has more...more mystery, resonance, richness, while being very clean. Last week MinringFIR shone on that track ; with ext2 I get interesting substance without MinringFIR's (perceived) damping effect

 

As of poly sinc mqa  : a new filter with n48 for me. linear won the comparison over poly sinc short on 24/192 Space Oddity. Guess there's no chance of highs roll off with 192 but mqa was more palatable, I'd say. Tried to nail it with Barenboim's Mozart's Quatuors (24/96). Piano sounded recessed compared to poly sinc short but strings more pleasingly flavoured. I have a bias against poly sinc mqa since it infatuated Serkin's piano (RB) ; playing Herbie Hancock solo 24/96, I'd say every note sounded like having more weight with poly sinc mqa and I have to admit I very much liked it ; maybe a guilty pleasure, time will tell.

 

As of poly sinc mqa mp : a new filter with n48 for me. Have not compared but enjoyed more than before difficult 24/192 "Pop" tracks such as Television's Marquee Moon

 

A last word in favor of poly sinc mqa : with poly sinc short the Barenboim's files sounded bass inflated ; with poly sinc mqa sound had more cohesion.

 

ext2 might become my favorite with RB and poly sinc mqa (mp) my favorite with hires + I can now keep CIC integrator/SAVE engine combo : 3.24 is a major release ; kudos and thanks

After some research, found the difference.

So, I am comparing the HQPlayer to the Jriver and to me it seems the HQPlayer is much more accurate and neutral where as Jriver is more emphasizing into mid bass and warmer upper mid.  I will have to say that for what I am hearing, the HQPlayer is superior....anyways I paid for them all...lol.  Given the price of HQPlayer, it does not disappoint at all !

Hi Miska, 

After trying several new filters and comparing them to the old favorites I am still quite impressed by ASRC filter. In my system and to my ears it gives very organic and natural sound which fits well to classical chamber or small jazz combos. I was looking again into manual and I see than sinc filter (which is ASRC now) is not recommended. Just of curiousity - why you include this and some other filters which are not recommended as well into the filters selection? If it is not recommended?

Thank you.

did you hear it ? Miska once said that ADD and SAVE achieve the same results  but that ADD should be preferred for its applied maths take a lesser toll on cpu.It thus could could be that I'm pleased by the influence of a noisier computer. However, like I wrote, SAVE sounds more organic to my ears, just as if my convolution filters were imprinted an octave lower inside the music files. What did you hear ?

The Sync-M filter has an issue playing DSD64 sources to PCM out. There is no audio and time counter rips through the track at about 5 x normal speed.

 

 

This is happening to me with sinc-M, but on PCM. Anything other than 44.1 doesn't output audio, the time counter rips through the track a lot faster than the correct time. The same fast speed occurs on Roon time counter at the same time.

 

Well, with PCM 44.1, the sound is absolutely amazing. My new favorite! It was closed-form-M before (that now is my 3rd favorite). But another odd thing using this filter is that the audio comes after 14 seconds of playing the track.

 

It's not like other heavy filters that "freezes" the system for some seconds before playing the track (only once after I launch HQP). With sinc-M, the playback starts immediately (on Roon and HQP), but the audio comes after 14 seconds, and audio stops when the track time ends, so I can't listen to the last 14 seconds of the track. This combined with the impossibility of playing anything other than 44.1 source (like MQA 48, 88 and 96 from Tidal on Roon) makes this filter impossible to use for me. I'm sad because it sounds amazing.

 

Poly-sinc-ext2 is now my 2nd favorite sounding filter, and the one I currently use on PCM. A pleasant listening.

 

I still didn't try the new SDM filters because my main DAC (Pro-Ject Pre Box S2 Digital) is far away from me, and my secondary DAC only supports PCM (Audioquest Dragonfly Red).

 

It's so nice when new filters are released, thank you @Miska

What is your output rate? Probably there's some bug in the filter's allowed conversion ratios rule...

 

The output rate is 176400. PCM source works fine with this filter ( both 44.1k and 48k families).

 

On an unrelated issue with pcm out, there is a snippet that plays from a previous track after stopping and starting a new playlist (like the contents of the last buffer) that only occurs with pcm out. This has been occurring over the last few versions.
