HQPlayer Linux Desktop and HQplayer embedded

Correct. Boots from USB. It's self contained.

 

Just need a web browser (laptop, tablet, phone) to choose your HQP settings.

 

Thx, why would one then want to install a different OS like Audio Linux?

I have a couple HQP Embedded machines. On one of them, I need a different OS so that I can run both Roon alongside HQP on the same machine (and some other stuff I do in Linux). I run Debian on that machine.

 

On the other, I run just Jussi's USB bootable OS. There are some on other threads claiming better SQ with Audio Linux so you'd have to ask them... I've tried it and prefer Jussi's USB bootable HQP OS myself.

I am curious as to why you would run Roon (as an end point or core) and HQPLAYERD on the same machine?

So that I don't need to buy another separate machine for Roon Core...

Thanks, and here comes my last question (not wanting to go off topic): Any performance issues with that setup? I am asking because I want to modify my current signal chain and would like to consider all alternatives.

Not off topic at all. Good question.

 

If you're pushing HQP to the end capabilities of your machine, then there's not much room for Roon to work without sending things 'over the edge'.

 

So I guess it depends what you're doing with HQP and what the capabilities of your machine are, whether you'll be ok with Roon running on the same machine.

 

In my case I know what the machine can and can't do with Roon running on the same machine and I'm happy enough with what it can do.

Hi @Miska

 

If running Ubuntu 18.04 LTS with HQP Embedded, is there an easy (and reliable) way to have Tidal audio (via Chrome browser) feeding HQPe input?

 

Or is the only way to connect a Chromecast Audio + miniDSP USBStreamer ?

 

To get Tidal audio from Chrome Browser (for example) it seems like a complex way to send the audio data out of the HQPe machine over the network, only to then have it come back into the same machine.

 

Is there an easier (but also stable) way, specifically with Ubuntu 18.04 LTS.

 

Obviously Roon supports Tidal, but there's a few things better with the official Tidal page (and app), that I like to use sometimes.

 

Thanks in advance

If it is on the same computer, you can use ALSA loopback device. It has it's own small strange things, but it should work.

 

Browser based Tidal is not very good idea though, it may not be bit-perfect input to HQPlayer.

What I have is Mac Mini (with macOS) doing output to AES which is connected to RME interface input to HQPlayer Embedded. Probably there are number of "streamer devices" with digital output that fit the bill, in addition to Chromecast Audio. But Chromecast Audio is absolutely cheapest and simplest device and with optical output has full isolation.

For Tidal, I use their app quite a lot and also Conversdigital's mConnect Player. Because this are simple to use from my mobile phones (both iOS and Android). I get same experience on both phone OS. And of course Spotify app too the same way.

Based on the timing of your comments, it sounds like you have even further EC modulator optimizations in mind. Is that correct?

 

Yes, I have multiple ideas how to optimize things, but it is not simple, so it'll take some time...

I have matrix set up for 5.1 downmixing to 2 channel as documented in embedded.  I also have an ir.wav file set for each channel.  Works fine for 2 and 5 channel flac.  The problem is with stereo 64 dsf converting to 192khz - cpu usage more than doubles to 80%.  If I switch to convolution instead of matrix usage drops almost in half.  Matrix seems to offer more than convolution except for the overlap settings.  Why are there two options, what are the differences? 

 

Convolution setup is simpler, for room correction purposes. Matrix things offer mixing, channel routing and such, but with cost of added processing complexity.

[audiofool]

I would be using Convolution most of the time for dsf and pcm and Matrix only occassionally for a few multichannel pcm files.  I believe I read that Convolution and Matrix are mutually exclusive.  I assume only one should be enabled at a time?  What happens with both enabled?  Is it ok to have Speakers Enabled at the same time as Convolution or Matrix in order to do minor balance adjustments?

Using trial version of HQPlayer Embedded.Every time I start HQPlayer i have to go in a change filter setting because it keeps reverting back to poly sinc ip ?

probably because you change on MAIN page instead of CONFIGURATION page

Hi @Miska

 

Are you going to be supporting Debian Stretch till June 2020 (LTS EOL date)?

Can't edit my above post but I meant "til June 2022 (Stretch LTS EOL date)?"

 

If not, you will make an announcement when you will stop Stretch support and moving to Buster?

 

[baconbrain]

Burned the embedded image to a USB stick, fired up the PC, adjusted the configuration, and it works like a charm.

 

Excellent!

I'm moving over to Buster. Just need some time to do it. Meanwhile the Stretch package may already work on Buster (I have not tested).

 

On Ubuntu, I move over to new LTS when previous becomes upgradeable to the new one, which in case of Ubuntu is .1 release. On Debian, new releases are supposed to be upgradeable immediately.

Yes, they are mutually exclusive. If you happen to accidentally have both enabled at the same time, it should still work in fairly reasonable way, but it is not really recommended because it becomes a bit confusing and thus prone to configuration errors. Speakers can be enabled in all cases.

Did trial version 4 with windows,linux and HQPlayer embedded.In windows and linux can do all dsd 256 filters with all modulators including the new ec ones.HQPlayer embedded not able to use new modulators at 256 as get stuttering.Why does it only stutter on embedded version /HQPlayer embedded sounds the best to me.

I run Roon Core and HQPlayer Embedded on an Intel NUC7i7. HQPlayerd upsamples to DSD128 and performs no further processing. The Intel NUC can handle this load so, I have no need to use use further hardware. It works for me this way.

Did you use Desktop 4.1.0 and Embedded 4.11.1? These two largely match in terms of DSP optimizations.

 

But I will continue trying to improve EC modulator optimizations to make them more available on various hardware.
