But you need to make sure 802.3x is active on the path from HQPlayer to the NAA. Has anyone been able to play native DSD512 48 or DSD1024 48 with RPi4 or RPi5 as endpoint? I get a nasty rattling noise with the music. DSD256 48, DSD 512 44 and DSD 1024 44 plays fine. A friend of mine was able to play DoP DSD512 48, but native DSD gets the same problem with DSD512 48 and DSD1024 48. Link to comment

Thanks! So do you think is a kernel problem? I don't have a RPi4 to test, but 2 friends tested on theirs and got the same problem. What's the kernel used by NAA OS? And will we have a NAA OS for RPi5? Link to comment

Yes, when it becomes feasible. All the needed software components are not yet RPi5 compatible. But it is finally starting to come together. fgribas 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

HQP Embedded is 5.4.0. sinc-long is non-apodizing though. Is that not a worry? The apodizing score is listed as 735. The source is a FLAC 16-44 file on the sda1 SSD drive on the same Ubuntu Server machine running HQPlayer Embedded 5.4.0 I have that same album, I am positive I downloaded it from Qobuz, in 24/192 and the Apodizing number is 0 for all tracks.

Above screenshot is from RedBook format. That vs 192k hires is a big difference. Worth taking a look at the HQPlayer's spectrogram metering though, so that it is not upsampled fake hires. But it could be also true hires transfer from original analog tapes. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Looks like a hires tape transfer. 48 kHz would have been enough for this, enough extra over 44.1k. But overall looks like a decent tape transfer and no need to worry about this one.

Popular Post Carousel Posted January 30 Popular Post Share Posted January 30 @AudioDoctor @Miska Reads like I should replace my Duke Ellington & John Coltrane. I probably have, at the newest, a 2007 CD in a box in the cellar. Looks like I only updated the album art in 2017 to a bigger picture than I had originally. Checking Discogs, I could look for a 2018 Stereo & Mono release, or a 2020 or a 2023. Don't know if you would have recommendations from there: Duke Ellington & John Coltrane - Duke Ellington & John Coltrane | Releases | Discogs. I might just try a couple Qobuz downloads and see how they measure. Maybe I start with the 24-192! As for my Babs & Duke, that is a 2016 CD rip... done in 2017. The apodizing count after 3 minutes of Stoona is only 7. And it sounds pretty good with sinc-long. So I take it, this one is OK as it is even with a non-apodizing filter. Right?

Typically newer releases are worse than older ones. Pink Floyd being one example of such. As time goes on, "remaster" usually means "we added more compression and limiting to make it sound louder". Yes, figures like <10 during a track is fine with halfband-style filters. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

I will test NAA OS when it's available for RPi5 so I can confirm if that is caused by a custom realtime kernel I'm using. Link to comment

DomiJi Posted February 1 Share Posted February 1 Hello HQPlayer fans out there, i am looking for a nice mini pc that can handle my Roon core as well as HQPlayer with PCM upsampling to 768khz and Closed-Form-M filter. Does anyone have some experience what kind of CPU is "enough" for that usecase? Thanks for your help :-) Best DomiJi Link to comment
