Leave it to the crew at Rational to actually have fun with their jobs.

When the technical writers get let off the leash once a year  :D
Here's this year's:

Rational Acoustics is proud to introduce a revolutionary leap forward in the field of sound system test and measurement. Smaart™VR brings the measurement platform you know and love into the future with full Virtual Reality support. Supporting the latest generation of VR headset systems including the Octopus Crest 2 and the NAI EVE, Smaart™VR brings you inside the measurement, creating total immersion in the data you’re generating.

According to Smaart™VR product manager Christ Sanjoures, “Our goal with Smaart™VR was to create a measurement platform that comes to you, and I have to say, I think we really pulled it off – once you experience your measurement in an immersive way – breeze blowing in your hair, soaring high above the phase trace, feet dangling into the Live IR – you’ll never go back. It’s like using an IMAX theater as your computer screen.”

Smaart™VR also speeds up measurement and tuning work in the field due to its “distraction free” workflow – the headset allows the user to focus solely on the measurement data itself, without getting distracted by looking around the venue at the actual system being worked on. Plus, the headset offers 20 dB of isolation in both ears, allowing the user to work in comfortable silence, without having to actually listen to the sound being produced by the system. In other words, Smaart™VR is perfect for users who just want to focus on the squiggly lines, devoid of any meaningful context.

Smaart™VR harnesses the full power of a modern desktop gaming PC to render the stunning graphical presentation of the measurement data. Laptop computers are not supported at this time, making Smaart™VR a perfect work-from-home solution to system alignment.

Justice - if you're running the v8.5 public beta, you will find an interesting new option in the Transfer Function "Import ASCII" dialogue  ;)
What am I looking at here?  :-\

{...} just in the last few years, we've seen Apple cease support for 32-bit applications, shift to a new CPU architecture, and deprecate OpenGL, {...}

Of course, this sort of insanity starts to increase the reasons to make a stand-alone unitasking platform like SIM.

Dropping OpenGL in particular sounds like a real kick in the teeth to anyone trying to develop cross-platform desktop software. At that point, a Linux port might be easier than continuing development for MacOS.

Open the FFT Size droplist - at the bottom is a "SIM .bin" option that can import a SIM3 .bin file and break the three contained response measurements (Room, Processor, Result) into .trf format and add them to your data library. Now all you have to do is get a CD-R so you can get the data off the SIM machine  8)

From the readme:

Quote
The “Import ASCII” dialog now supports importing SIM® 3 .bin files. Simply choose “SIM .bin” in the FFT
droplist, then browse to the location of the .bin file and choose it. Note: SIM® .bin files pair with a
corresponding .xml file, which must be in the same directory as the .bin file for the import to succeed.

At this time, only Transfer Function data is extracted from the .bin file. Each measurement group within the
.bin is analyzed and the Room, Processor, and Result data is extracted to separate Smaart .trf trace files. For
consistency, the extracted Coherence data is square-rooted; if the desire is to emulate a SIM® machine’s
display, enable the “Squared Coherence” setting in Transfer Function Options to square all Coherence traces
prior to display.

I don't mean to pick on Macs (too much)...although I lean towards Windows myself, the reality is that a lot of this work in the field happens on macs, so if you can't run on macs, you are limiting the usefulness of your tool, and Windows is certainly not without its snags - audio-related tasks, in general, are more finnicky on Windows than macOS, so as Jamie would say "we hate all operating systems equally."

Dedicated hardware is yet another can of worms, and the economies of scale are basically non existent for the size of the industry (RIP Smaart IO). Luckily the dev team is really on top of things, and these are the things we are attacking now with v9 on the horizon - a deep dive into how Smaart communicates with audio hardware, overhauling the entire renderer...  I can't say much more along those lines for the time being but the idea is to build a solid, flexible, capable code base, which creates a nice strong foundation to build the "fun" stuff on top of.

Very happy for the RA crew.
No clue if it matters business wise,
but having heard bits and pieces of history in various Smaart classes, it sounds like Meyer's dropping SIM and adopting  Smaart is something of a full circle journey.
Good stuff happens to good folks !

{...} Dedicated hardware is yet another can of worms, and the economies of scale are basically non existent for the size of the industry (RIP Smaart IO). {...}

I suppose it depends on how dedicated "dedicated" is. In my mind I was picturing something along the lines of a SoundGrid server, rather than something like Smaart IO (or SIM, for that matter), i.e. something that is almost entirely off-the-shelf (both hardware and software) with only just enough customization to do the task (and, when it comes to packaging, keep the marketing department happy). I'm not sure if that actually solves any problems or not (it would certainly create some!), but it might at least reduce the number of entities that can screw you without warning or recourse. (My own personal opinion is that MacOS dropping OpenGL support is borderline anti-competitive, if not in the technical sense then in a practical one.)
