Next step please

You can put this in a .txt file and do same process you already use with headphones?

Make sure you add “preamp gain” to avoid clipping

Moy · October 29, 2022, 10:14am

Oooook!!! Will put a -4.00 to test it!

dabassgoesboomboom · October 29, 2022, 10:16am

Use the “plot” function in HQPlayer to check before you press play.

Same like we previously discussed with headphones.

Make sure nothing is above 0dBFS

Moy · October 29, 2022, 10:34am

Looks all good

dabassgoesboomboom · October 29, 2022, 10:49am

Well I can see some stuff above 0dB in magnitude plot

Might cause clipping… Maybe -10dB of preamp gain will help ?

You can add to the txt file or to the line discussed the other day, in HQPlayer

dabassgoesboomboom · October 29, 2022, 10:51am

Also doesn’t match the EQ plot in your app screenshot.

Good thing to check everything carefully, and then double check, before playing…

Same process as checking oratory EQ plot for your headphones…

Moy · October 29, 2022, 10:55am

This is another curve plot. Will now put Curve B (edit)

The correction is in purple

dabassgoesboomboom · October 29, 2022, 12:24pm

EQ curve shape looks ok at a quick look. But you still need to add preamp gain - you have boosts above 0d which will/might cause clipping.

And then enough plots - share how it sounds ! ?

Moy · October 29, 2022, 2:47pm

The sound I noticed is quite “clean”, too “clean” like missing a bit of roughness, don’t know how to explain it. Is interesting, but I need a bit of “noise”. Is quite interesting. I was testing it at DSD256 with ASDMSEC7v2 and poly-sinc-gauss-hires-lp. But is interesting. Will test House Curve C.

The sound is so good already with HQplayer SDM noise/dither shapers

jussi_laako · October 30, 2022, 3:11am

Here is the highest gain the EQ. Although it is surrounded by lower ones. But just to be safe, without having a specific Preamp-line, use -9.9 dB as gain for those pipelines to compensate for the potential maximum gain. As a result, you will need to turn up your volume, which is normal, because only relatively narrow bands are boosted (rest being much lower).

Moy · October 30, 2022, 3:27am

Many thanks for eye ! @dabassgoesboomboom also mentioned it. Will make the updates.

Moy · October 30, 2022, 6:51am

Everything was working fine, suddenly sound muted but keeps playing on HQplayer on ifi Neo

Unbuntu HQplayer Desktop for DSD512
Mac Mini Running Roon
NAA
ifi NEO iDSD 512x48

On my DAC-60 DSD256 is ok.

When I switch inputs on DAC from Bluetooth to USB sound comes back

Using latest Roon version.

Any ideas? Thanks

Edit: seems I’ve found the issue, the NAA ethernet cable was old with something lose that was causing the problem, when I touch it the music came back. Now seems all stable everything is on same switch. I also removed and added back the HQplayer DSD512 zone!

It’s fixed! Party is back

Moy · November 14, 2022, 3:31pm

Hi while updating
sudo dpkg -i /home/hq512/Downloads/hqplayer4desktop_4.20.0-97_amd64.deb

got this:

dpkg: error processing package hqplayer4desktop (–install):
dependency problems - leaving unconfigured

Errors were encountered while processing:

Edit:
Fixed with sudo apt -f install! All dependencies fixed!!

After update no longer @512x48 ECv2, got drops like before. Other filters are okay

Testing now 7EC 512+fs

can I downgrade?

jussi_laako · November 14, 2022, 6:26pm

Can your CPU run the AVX2 build instead?

Moy · November 14, 2022, 10:56pm

Can you please explain more details what steps I need to do? Many thanks

Edit: this?

jussi_laako · November 15, 2022, 12:07am

Why on earth are you doing this!? Don’t do such.

Install hqplayer4desktop_4.20.0-98avx2_amd64.deb instead of the one you installed earlier.

Moy · November 15, 2022, 12:19am

Ups ! I will do the install later to test. Newbie here

For what I’ve done already is it bad? Do I need to to undo ?

Moy · November 15, 2022, 12:21am

So I just download and install like previous version right? It will replace current version of HQplayer?

jussi_laako · November 15, 2022, 2:08am

Just waste of disk space, you can easily undo with “sudo apt remove libmkl-avx2 ; sudo apt autoremove --purge”

Yes, package manager just replaces the previous package with the one you specified. It is pretty straightforward.

Overall, if one’s CPU is AVX2 capable with > 4 cores, very likely the AVX2 build performs best. Maybe I’ll just add more download buttons to the web page.
