As always the detection of changing sampling rates could be tricky. There's yet another example that looked like this https://imxdev.gitlab.io/tutorial/Audio_loopback_between_two_imx_using_USB_UAC2/ Someone was trying to work on a new version but that didn't go anywhere since 2017 https://lore.kernel.org/patchwork/cover/848755/ https://lore.kernel.org/patchwork/patch/848754/ https://www.mind.be/fosdem19/2019-02-03-FOSDEM2019-C-usb-audio-class-3.html That's awesome, I'm looking forward to that article because someone else reported that streaming from JRMC to HQPlayer Embedded via UPnP turned out to sound pretty darn good https://www.my-hiend.com/vbb/showthread.php?13157-piCorePlayer6-1-0-Xenomai-44-1-48KHz雙機入門簡易安裝教學&p=244284#post244284 Rooted Android devices with an app called AirMusic could stream Apple Music to HQPlayer Embedded via UPnP, I guess that's a fairly decent solution when compared to other alternatives. Good stuff @seeteeyou. I'm looking at the Pi solution you linked to right now. Sometimes it's fun to dig into this and get our hands dirty, while other times it's just fun to press play and not thing about it. Founder of Audiophile Style | My Audio Systems Link to comment
The Computer Audiophile Posted August 17, 2021 Author Share Posted August 17, 2021 Looking at the Pi solution, it has the right idea, but requires software installation on the host music server. This won't work with a Linux server that doesn't allow root access by end users unfortunately. Founder of Audiophile Style | My Audio Systems Link to comment

With an Innuos, you could go AES out to a Merging HAPI then Ravenna to an HQP server. The HAPI would be a D to D and clock. 10 minutes ago, bbosler said: I really don't see where this is worth the hassle when you can just use any number of programs on your CAPs PC as the music server. (I know you mentioned that) . Even if Aurender is somehow a superior sounding server, don't you lose that superiority by funneling the output through another server running additional software that is going to up sample and apply convolution? If it is all just so you can use the Aurender interface seems again to me not worth the hassle just for that It isn’t for everybody. Founder of Audiophile Style | My Audio Systems Link to comment

They work great. It s allows lower frequencies to play nice with the rest of the Freg Resp. and hear all the bass detail the system is capable of delivering. I guess I'm not sure why this is not a popular option? Yeah, DSP is so good now. I can’t believe more people don’t use it.

Not trying to bust your chops, but I really am trying to understand why anybody would pay big $$ for a streamer then process the hell out of the stream. I thought one paid big bucks for a streamer because the digital output was somehow better than you can get from "lesser" streamers? Seems counterproductive to pay for an expensive streamer then run the output through several more boxes before the signal gets to your DAC. Are you saying that the Aurender feeding HQP this way sounds better than Roon or some other program feeding HQP with the same settings? Again, I'm not trying to give you a hard time, I just don't understand the purpose of the exercise other than to say you got it to work. .. which is fine I understand it's "not for everybody, I just don't see why anybody who wanted HQP would go to such lengths and $$ when there are a multitude of one box solutions..... of course other than just for the fun of doing it thanks for pushing the envelope though Think about it this way, people have spent $20,000 for a high end server and it has full support by the manufacturer. They love the server. Adding another tool in the toolbox by enabling DSP this way is now an option. They don’t have to sell the server at substantial loss and they can stick with what they like. This article is also a proof of concept article. This is a start, to get the ball rolling on using DSP with components that “don’t” support it and without getting rid one one’s components.

Anything is possible, but which protocol are you going to use to send and receive audio? Ravenna? 2 hours ago, R1200CL said: What does The Sonictransporter lack in order to be such a device? It has Roon, where you add the room correction filters. It has optional HQplayer embedded built in. Yes it lacks AES/SPDIF, but apart from that, isn’t it pretty close to your dream ? It lacks the ability to input audio. Tons of people are over or never got into Roon. As I said in the article, using Roon for this isn’t an option.

Theres just one PC and an Anubis: Audirvana and AcourateConvolver uses ASIO so: Qobuz and local files>Audirvana with upsamling>Acourate Convolver4channels up to 192>Merging Anubis>amp/main speakers and subs What I think could be even more cool would be to have the convolverfilters direct in Audirvana or another playerprogram and then upsample right before sending the data to the Anubis. One question: once you use DSP, you alter the sound to your taste, does it then still make sence to buy a very expensive dac.....what I mean is that I would probably not have bought a pro dac for being used without DSP. Chris you never wrote a review of the Anubis, that would be nice to have your take on this quite special dac with so many possiblities, does it compare to the elite etc. Thanks Hi Jørgen, thanks for reading and enjoying the article. Yes, this one is quite complex and it isn't for everyone, that's for sure. I my view the DAC is always important. The conversation from digital to analog can be done many different ways, and they all matter. I really should write a review of the Anubis. It's an incredible tool with unlimited potential.
