m1-web-spatialaudioplayer
Consolidated Mach1 spatial audio player focused on collecting all headtracking input methods and defining best practices
Here's an absolute nightmare example file tree, from the newly open-sourced Valve's audio engine called Steam Audio:
It is far easier to use a non-Windows operating system and simply direct the IQ data into the application you want, or use a better app which can take data directly from the RSPdx. However, in an RTL-SDR book, I saw a reference to VB-Cable, which is a separate software from VAC. Pipewire is another tool, definitely open-source and free, which should work.
Somewhat tangential, but here's a cool somewhat open-source project related to Dolby Atmos:

https://github.com/VoidXH/Cavern
The visualizer, which is what I was _most_ interested in (along with software decoding) is written in C# and the rendering is done in Unity -- both things I valued & thought were cool. In theory, you could build a DIY multi-channel "receiver" with this type of software if given enough audio outputs (and/or put something like Dante to use).
I explored it a bit further but it's relatively cost prohibitive, especially if you want to do something like accept HDMI input, it gets messy. AFAICT, at least when I went down this research path a few months back, even finding & getting dev kits/boards with HDMI input (of semi-recent generation) was non-trivial & pretty pricey.
