HQPlayer Embedded Discussion

Damn.
For my next HQPe machine, I should get the Seasonic ATX 3.0 PSU soon, before the ATX 3.1 version replaces it.
Didn’t plan for this, but seems necessary. :confused:

Using an old embedded ver 4 license on an old Rpi4 connected to my DAC-60

I’m amazed how this little thing can push DSD64. It drops sometimes when processing higher resolution files, but in PCM 384khz is stable.

This is more nostalgic than looking for the highest resolution, reminds me when I discovered HQplayer and started playing with it. Vintage DSD anyone :joy:?

Which filter(s) would be good for highly compressed music?
I recently got one and am puzzled by how the anodizing counter rises in a few seconds. :confused:

Depends on the music genre. But the apodizing poly-sinc-gauss filters are good (please check the filter table in the manual). Depending on the content you can also try poly-sinc-gauss-hires-* and “poly-sinc-mqa/mp3-*”.

Thank you!
It’s a popular animation movie soundtrack. Artificial digital music.
Didn’t have to be highly compressed, but that’s how it is and can’t be helped.

I do check the table to see which filters are apodizing. :wink:

I’m starting basic research on how to use Audiolense. (At least I figured out what it does.)
Do I also need Ozone 10 or Neutron 4 to use it?

No audio mixing software is required to use Audiolense.

Measurement microphone + Audiolense + HQPlayer is enough…

Thank you! :))

The only issue is figuring out a way to run sweep with hqplayer dsd for audiolense - I wonder if anyone else has done this and can advice on a way to do it ?

I don’t think this is needed. And I can’t see how the time domain correction could work well.

For optimal measurement and optimal correction (especially True Time Domain correction feature of Audiolense), you need lowest latency, where Audiolense plays and measurement with only one ASIO interface driver involved

Jussi would need to create some virtual ASIO driver. I imagine he has more important things to do :grinning:

If Jussi were to create his own room correction software/ HQPlayer feature, well that would be interesting

And audio mixing toys ( with ASIO) to do the job better

The Focusrite interfaces are fantastic for measurements.

Even for playback (HQPlayer output set to PCM192kHz).

Especially when multichannel DSD DACs (all are ESS based) are quite expensive

I do run an Artpro USB ii interface with a Sonarwork mic for audiolense.

Hi @jussi_laako

I have set the parameter " PCM gain compensation (dB)" in HQPlayer Embedded configuration to -1 after the values in the table for AKM 4493 DAC. I own an ADI-2 DAC FS (v2) and, as you know, with DSD (Direct) sources sets (and locks) the volume to -1 dB itself. So I wonder if I could set the parameter to 0 on HQPlayer Embedded because the DAC is already applying the compensation. I presume it is the same compensation, perhaps I am mistaken.

Maybe yes… Although if you don’t use PCM output mode with the DAC it doesn’t matter since it only applies to PCM output.

Hi @jussi_laako,

I experienced an issue upgrading to Embedded 5.11.2 from 5.11.1.
Ubuntu 24.04.2 LTS (GNU/Linux 6.8.0-55-generic x86_64)

Initially I accepted the new version of the config file /etc/hqplayer/hqplayerd.xml and then loaded my saved profile (DSD 1024 sinc-Lh and AHM7EC5L). However HQP defaulted to PCM, reported PCM output through Roon but did not play. Also, the Matrix tab did not recognise any available DAC correction (I use Spring3/May usually).

All reversible by downgrading to 5.11.1.

I then upgraded again to 5.11.2 without accepting the new config file and I could load my profile, apply DAC correction and play music without a problem.

Anything in the log file or service output? I only changed the default settings in the configuration file, that’s why it is offering the new configuration file, because the packaging system detects it has changed from the earlier version. When updating the software, I would recommend not to accept the new configuration file.

I will check if I can find why such happens.

I installed HQPlayer Embedded 5.11.2 because of EC modulators optimizations, just for testing purposes.
With my current setup: NUC 7i7 running Roon Core and HQPlayer 5.11.1, poly-sinc-gauss-long and poly-sinc-gauss-hires-lp, DSD256x48. I could use ASDM7 modulator and ASDM5EC-ul, but no any other 7th order EC.

After the upgrading, I can use ASDM7EC-ul, ASDM7EC-light and ASDM7EC-fast. Nice forward step!!

Which would be the preferred order (from better to “less” better)? fast-light-ul, perhaps?

They are all good, but have somewhat different sonic character (and CPU load). So I would select the one that you prefer from sonic point of view. You can easily switch between the modulators on the fly during playback and compare. Or ask someone to switch for you.
