HQ Player

Hey Miska

 

Question for you. I have an audio interface (ADC / DAC) that I would like to run my turntable into and also use as my output device. ASIO input and output. RIAA correction is applied via convolution.

 

I'm doing this now with jriver. Possible to do with HQPlayer?

 

Thanks,

Jim

Hey Guys

 

What horsepower is needed to upsample 16/44.1 to DSD (128 or 256)?  Can a new Apollo Lake NUC do it?

 

Thanks,

Jim

Like maybe a minimum PassMark score or something like that?

Hey guys, what does the purchase of a license get you in terms of updates?  I'm probably just not seeing it...so a link is totally cool...but if I buy it now...which is on version 3.17...how many more updates does my $ get me?  

 

How many more 3.x versions are expected?

 

Thanks

Jim

How many you want? 

I mean, I just want to know what my $ get's me.  Is 4.0 around the corner and I got pay another $163 (or whatever) for it?

Indeed!!  Thank you, sir!!!

Hey guys, is the license transferable to someone else?  I.e., can I sell mine?

 

Thanks,

Jim

I don't think so because license is personal

Ugh, figured as much.

 

Oh well....my bad.

Miska, any chance you can incorporate biquad filters into HQPlayer?

 

Btw. the importing of REW PEQ filters worked perfectly!  Thanks!!

HQPlayer has such, but the question is more what/how would you use those?

 

 

Oh, great!

 

I'll be using them for ultra-accurate RIAA correction.

So you'd want to just provide raw biquad coefficients? Tricky part is that those are sample rate specific. Which is of course not so much of an issue for RIAA since you can known the ADC sample rate in advance.

 

But I think the existing IIR EQ components could be useful for the same purpose without being sample rate specific.

 

 

Yes, I  want to use raw biquad coefficients.  You're correct re: them being sample rate specific but, yes, I know the ADC sample rate in advance.

 

I'm digitizing at 192khz which will remain for the forseeable future so no real issues for me on needing to switch biquads.  

 

The biquads provide a REALLY accurate way to do the riaa correction (significantly more accurate than what can be achieved with the existing IIR EQ components).  So, just really about going for the best result possible!  :)

I'm curious why do you think so? Because the IIR EQ components calculate biquad coefficients for the rate in question and preserve full accuracy of calculated coefficients. There is always some potential for precision loss (not much though) when passing decimal numbers for biquads.

 

The deviation from the true RIAA curve of the IRR EQ methodology is significantly (orders of magnitude) higher than using biquads.  There are some threads on diyaudio that speak to it and this fellow Scott Wurcer published an article in Linear Audio which really details it.  Conceptually this whole thing goes back to comp.dsp days and Robert Orban's posts on the subject. 

 

A more recent discussion is here:

 

https://www.diyaudio.com/forums/pc-based/353387-phono-preamp-riaa-eq-using-iir-digital-filters.html

 

The dialog transgresses kind of quickly but a conclusion that can be drawn is that not using biquads can get you "good" results but its not the most accurate approach.

 

I think we should be striving for the best!!

Miska, I've set up my system such that the output is through a Gustard X16 via ASIO and the input is the analog line inputs of a Motu M4.  I see the input sample rate go from 192khz to 48khz and am not sure why.  This is an excerpt from the log:

Miska, I'm still trying to get my input / output setup working reliably in HQPlayer.  I've switched the input side (Motu M4) to use ASIO and the output side (Gustard X16) to use Wasapi.

Miska, what is the format for entering IIR biquads?  I'm working with this:

 

Coefficients for H(z):

 

num[0] = 6.758358e-003, [1] = -6.648568e-003
-------------------------------------------------------------------
den[0] = 1.000000e+000, [1] = -1.931275e+000, [2] = 9.313852e-001

 

 

Audacity Nyquist biquad equations (LISP format):

 

(biquad s b0 b1 b2 a0 a1 a2)
(biquad s 6.758358e-003 -6.648568e-003 0.000000e+000 1.0 1.931275e+000 -9.313852e-001)

 

(biquad-m s b0 b1 b2 a0 a1 a2)
(biquad-m s 6.758358e-003 -6.648568e-003 0.000000e+000 1.000000e+000 -1.931275e+000 9.313852e-001)

Does anyone have coefficients for RIAA correction biquads for rates greater than 192kHz sampling rates?  

 

I finally gave up on the TASCAM UH-7000 for phono preamp and A/D and bought an ADI-2 pro fsr which can sample up to 768k or DSD, both of which I think can be piped into HQP for RIAA correction and then convolution of RC filters. I still haven't quite figured out how to implement parametric eq parameters in the HQP interface though.

 

I would recommend creating a convolution filter using rephase.  I was heading down the biquad route and Miska showed me the way to even better accuracy :)

[jdubs]

scintilla, can you simultaneously input at DSD 256 from a source (turntable) and output at DSD 256 with the ADI-2 Pro?  WASAPI Exclusive / ASIO.

New Desktop has to be soon, right?  Soooo looking fwd to that RIAA plugin :)

How does one use the new RIAA plug-in?

You put "riaa" as one item on the matrix pipeline process for the channels where you want that. You can use Plot button to see the response too.

 

Awesome - thank you!  Any commentary on how this plug-in was constructed, specifically as it relates to accuracy?

I do vinyl playback with HQPlayer and it works GREAT!!   I run balanced out from my turntable into the mic inputs of my Focusrite Clarett 2Pre USB.  Conversion is at 24bit / 192khz.  Then RIAA correction and upsampling / conversion to DSD256 prior to output from my Gustard X16.

 

Btw, Miska, the new RIAA plugin does not start at +20db and end in -20db.  It starts at 0db and ends at something higher than -40db.

 

Any specific rationale behind that?  The overall output is very low because of this (and the fact that there is not a 40db differential between 20hz and 20khz is curious).

Jussi I'm a little lost. Could this be done?

 

TT -> Phono Stage --> RME ADI2 PRO Analog --> HQPlayer PC (RIAA) -> RME ADI2 -> Pre - Amp - Speakers ?

 

 

You wouldn't need your phono stage in the above, assuming the ADI2 PRO provides enough gain.
