May I ask how you use it as a VST plugin, what makes the apps nice (is it only that they are available?), and what and how you connect with netjack2?

Loading the VST in Reaper makes it fantastically easy to turn just about any Android or iOS device into a monitor. Great for checking the final mixdown for YouTube videos and EQing my podcasts in real time. It is also handy for bringing a guest onto a show since I can wire things up to use the mix minus in the studio without relying on AEC.

I did my best to explain the NetJack2 layout in my studio in this post https://interfacinglinux.com/2024/03/02/lossless-network-aud...

Looks seamless when you use it like that. As a "normal user" of a desktop OS, network audio always seems so custom, I guess how the OS and applications handle audio is always going to be the bottle neck. I have no need for a DAW but I often want to stream audio from something to something else e.g. as you say monitor audio on some other device.

Side note: SonoBus internally uses my AOO C/C++ library for the actual audio streaming and peer-to-peer communication. See https://aoo.iem.at for more information.
