Happy New Year to all.
My ripped or downloaded music files are stored directly in harddisk at home. I am using Audirvana Studio to stream music within the local network at home. But I would like to understand more if I can still stream my music library while i am away from home, on the road for example. Or I should use another media player to access my own music collection remotely anywhere? Please advise 
In the case of Audirvāna that would require another player.
I am primairily using Roon here at home. And through Roon ARC it does exactly what you want it to do.
Audirvāna is very limited in this regard.
I am told that Audirvana origin and Audirvana Studio are indeed different products. Audirvana origin is the older version lacking remote streaming support, while Audirvana Studio includes this capability, supporting remote access to your music library, allowing you to stream music from anywhere. Anyone could advise?
That’s not accurate. Audirvāna Studio isn’t to be used outside your home network.
Yes, there is a remote app, but that functions as a duplicate of the Audirvāna Interface on the device where it is installed.
So your phone or tablet becomes the device with which you control Audirvāna within the local network.
Where Audirvāna Studio differs from Origin is that with Studio you are able to integrate your subscriptions with streaming services like Qobuz
Audirvana Origin and Audirvana Studio are basically the same product. Origin was created next to Studio. The difference being that Origin has all the streaming functions of Studio disabled.
Some people don’t use streaming and didn’t want to pay for a subscription for Studio, hence the Origin version of the program.
If you’re up for a DIY solution, there are Subsonic, Airsonic, and two forks of Airsonic-Advanced. But using these takes a bit of doing if you want it done right. I use Airsonic-Advanced (reverse proxied with Caddy web server) myself, but Roon is more convenient in return for its cost.
Note: Also possible to use Audirvana with a travel router and OpenVPN, but I don’t know how that works myself, I just understand it’s possible.
I have a lifetime Roon subscription. And it works great here. So I don’t see a reason to change to something different.
Fair comment. I suppose that if you set up a VPN server in your home network, and you choose to play music in Audirvāna on your phone on which the remote app is running, that it might be possible to play music whilst traveling.
Maybe @Antoine could shed a light?
Apparently should be OpenVPN because of the network level it works at. I wish I knew enough to explain it to you, but the people who told me are knowledgeable and I trust what they say.
I have never tried this, but with a VPN server, you can connect to your home network anywhere, so playing music through Audirvāna might be possible.
Please be aware that to do so requires a strong knowledge of network security. I, however, do not have the time to do such an experiment, but maybe someone on the forum has already done this 
As does JRiver !!
Thank you
That seems to be about accessing your home computer remotely, rather than taking the audio processed by Audirvana on your home computer and streaming it to a remote location.
Hi @Antoine. What I understand from others is that one wants a TAP rather than TUN tunnel, the former providing Ethernet packets (layer 2, the data link layer), the latter IP packets (layer 3, the network layer). OpenVPN, I’m told, has a layer 2 mode that will do this.
I haven’t heard about other VPNs having such a mode (for example Tailscale, an offshoot of Wireguard that I’m currently using).
Edit: Just wanted to note that I have tried to stream Audirvana remotely through a travel router running the Tailscale VPN, and it did not work for me, apparently for the reason mentioned above.
Do you really want to stream processed files, rather than have the primary files being transmitted to the remote player where the playback processing is done locally in the player?
Seems the latter is the preferred methodology… I personally, think it is a matter of time before Audirvāna is running on M series iPads… Either way we are really talking about a very niche demographic of users… Although it is an interesting technical exercise…
Yes. 
I haven’t looked into whether it would be possible to take the local files I stream from my home with Airsonic-Advanced and process them through Audirvana remotely, though that would be interesting as well. Perhaps the URL I’m using for Airsonic-Advanced could be added to radio stations? @Antoine?
What is the advantage of streaming processed files, over having the local player do all the processing?
I admit here that I am out of my element, however I find the exercise interesting…
It seems this may be relevant:
Yes, I’ve published an article on another audio site about how to use an Airsonic predecessor, Subsonic, to securely access home audio remotely over https, without having to pay NordVPN or another provider. Airsonic itself is rather outdated by now, which is why I use the more active of the Airsonic-Advanced forks.
The trick then, which the link doesn’t address and I haven’t looked into, is how to feed the streamed file to Audirvana at a remote location.
That’s one reason for thinking about streaming a file Audirvana has already processed. Another is that my travel router and microRendu take up less space than the laptop I’d need to run Audirvana if streaming unprocessed files.
