Miska / Jussy,

An additional question HQplayer is also usable between the several platforms. Ps. I cannot find this on your webpage.

 

HQPlayer is a high quality audio player for Windows, Linux and macOS

 

I.e.  Using Mac Book Pro  as Client and  PC with Ubuntu as  a Desktop? 

 

Yes, certainly, any combination between Client and HQPlayer is possible.

This reminds me of a minor question about the command line syntax.

 

What does "5" signify in the following command?  Why does it not work if I omit the "5"?

 

--set-transport 5 'audio:default/44100/2'

 

Number is type of transport, second argument is parameter for that transport.

I currently use 
Roon > HQPlayer Desktop 4 (384kHz DRC Convolution filters. Upsample to DSD-256) -> NAA -> DAC
I have no problem sending all types of sample rate files through that chain.

 

Now I want to try a VST-plugin infront of HQPlayer realtime input, e.g
Roon > VST-Plugin > HQPlayer Desktop 4 (384kHz DRC Convolution filters. Upsample everything to DSD-256) -> NAA -> DAC

I will start and see if I can get automatic switching going with ASIO through the whole chain and set HQplayer to
"audio:default/0/2/pcm"
But probably the VST host and "virtual loopbacks" need a fixed sample or will upsample to a internal fixed value. But I have not tried.

So lets say I need a fixed value in HQPlayer realtime input.
How to think about this?

In Roon I have both 16/44k,48k and 24/96k files. Also some 192k and DSD files, but can live without those.

 

1. Should I config HQPlayer to
"audio:default/96000/2/pcm"
and upsample everything to 96k in Roon? Or better try to upsample to 384k in Roon when I have the Wav DRC Convolution filters generated in that sample rate?

 

2. If I upsample to 96k before HQplayer is it better to also generate and use 96k DRC Convolution Wav files in HQplayer?

 

3. Or is upsample before HQPlayer and then again inside HQplayer a bad idea "soundwise". So if automatic switching not working, better to set up to either play 44k or 96k files?

 

Do not do any rate conversion before input to HQPlayer. If automatic rate switching is not available, you should change the rate manually from HQPlayer.

 

That is likely downside of virtual loopbacks.

I have moved the topic here because my question relates to HQPlayer.

 

What are the advantages of 10 cores or 20 threads if only 5-6 cores are used with the EC modulators?

 

More cores left to run filters. But on the other hand, adding cores usually decreases clocks speeds which in turn make modulators suffer. This can be worked around by using GPU to assist lower core count higher clock speed CPU.

I'm using EVGA Nu Audio card.  If I try to set SDM Pack to None, it always reverts to DoP.  @Miska what am I doing wrong?  This is on Windows 10 Version 1909 with HQPlayer Desktop.  Nu Audio firmware is Version 0.30.

Driver is 0.2.1.2.

Now I am using the T + A M10 power amplifier. This inevitably leads me to the question of what I do with my T + A PA 3000 HV, which is superfluous as power amplifier. The use as a preamp, which is possible, does not make sense. My Denafrips Terminator DAC has no preamp function.

 

So I have dealt with the volume control of the HQPlayer. Under settings I changed the bandwidth to 0 and -60dB. The volume control should be done via the HQPlayer client. The Denafrips Terminator is directly connected to the M10 Power Amplifier via XLR. 

 

The positive first:

 

Contrary to my previous experience, the digital volume control sounds really good. I have to keep testing.

 

Negatively, I noticed the operation of the HQPlayer client. The volume control is activated with a double-click and presents a bar. This starts with 0dB! I am glad to have moved the bar down quickly, otherwise I might have killed my speakers. Under settings, I have now changed the bandwidth from -10dB to -60dB. Miska, please change this design and always start with the lowest value, in my example with -60dB!

The digital volume control inevitably leads to loss of bits. At the moment I have nothing to complain about the sound. But I can see that the CPU usage at -35dB has almost halved. In opposed to -4dB (DSD 256 with EC7). Is that the result of the lost bits? Do I possibly lose valuable music content?

I am very sorry. Somehow I accidentally changed the setting to Non-EC AMSDM7 512 + fs. After changing to ASDM7EC the CPU load is the same as before. Nevertheless, I would be interested in how the HQPlayer has implemented the volume control.

New insights with the HQPlayer volume control: comfortable to use with Roon! The HQPlayer settings (bandwidth) are transmitted to Roon. Click on the speaker icon to open the Roon volume control.

Don't you mean NAD M10?

 

No, the device name is random. There its T+A M10 mono power amplifier right in the picture. On the left is the T+A PA 3000 HV integrated amplifier, of which only the preamplifier is needed.

I am now testing whether I can do without a preamp, in which I use the volume control of the HQPlayers. 😉

Are you using ASIO backend/driver? That should represent native DSD. WASAPI backend doesn't support DSD, so through WASAPI DoP is the only way.

Hi Gabriel,

 

a kind of downsizing? 😮 Imagine you would have purchased the T+A SD 3100 HV (with integrated NAA!) instead of the Termi (and the Monos). Or the SDV 3100 HV. Now with your Monos you could sell the HV amp. 😉

 

Cheers,

Mario

Hallo Miska / Jusyy,

 

You wrote a few days ago " Some loopback software may work with the input feature. Another alternative is to use two computers or multiple audio interfaces and use the same input feature, but through S/PDIF.

 

Can you please specify which software you mean. And is it suitable on Apple iMac/ Mac mini too?

Ps. Nowadays I am using use the toslink iinput on my Mac mini bt maenad of Airport Express. 

 

 

Dear Miska / Jussy, can you please elaborate. Thanks in advance.

The startup value is what HQPlayer server side has. And HQPlayer server remembers the last setting when started again. After clean installation it starts with minimum (-60 dB) value for the reason you stated.

 

There are two other ways to adjust the volume from Client. One is that you hold down left mouse button on top of the volume tumbler wheel and drag it up or down. Another is to use flick gestures.

If you are using DSD output, there are no bits to be lost. Volume control doesn't directly affect CPU load, only in case you are hitting the limiter at higher settings.

I have not tried any other loopback software ever than the ALSA's built-in loopback driver on Linux. So I have not much to comment on that front.

 

That’s a pitte. 🥴

RME is coming out with the ADI-2 FS Dac soon.

It seems that it goes to 192 HZ not 354 like the original one did, thus enabling DSD 256 on Macs.

So will the FS Model not get DSD 256 on Mac?

That's the reason I would want to get one.

Disappointing if it drops the DSD 256/Mac.

The Pro FS  version has 384, but costs more, up to $ 2000, tho it's on sale for $1500.

Can Tech people check it out?

It's at B&H Photo, for one.

Yes, I'm using ASIO backend.  I see my mistake now.  I was trying to set SDM Pack to none under the input device settings instead of the output device settings!  Sorry about that.

 

Do you know whether Nu Audio supports 48K DSD rates?  And what is an appropriate value for DAC bits on the Nu Audio card?

Yes, at least on Linux it both works at 48k DSD rates and also seems to produce correct results as well.

 

Just leave DAC Bits at default (which should result in 32-bit). But that anyway matters only for PCM output modes.

I would be very surprised if it doesn't support up to 768/32 like the earlier Pro and DAC.

 

There could be some confusion though, because in "Class Compliant Multichannel mode" ADI-2 is max 192/32 PCM and DSD64. In "Class Compliant Stereo mode" ADI-2 is max 768/32 PCM and DSD256.
