I have an iMac Pro, so I think I have the umppf... I don't think these processes are CPU expensive, although they recommend the sample rate to be 1024bits.Thanks! Would be interested in your Mac hardware specs (model, cpu, ram) etc and how things go if/when you try a mix with multiple tracks and plugins plus while also running the Dolby Atmos renderer etc.
It seems an apple machine running both Logic Pro and the Dolby renderer is the most affordable path for Atmos music production. In the Windows world I believe the Dolby Atmos renderer must run on a separate machine which can only procured from an authorized dealer, so much more expensive and complicated.
I don't yet own any Apple hardware up to the task of doing all this so am of course looking at the ARM based machines. At one point not too long ago ARM and/or the latest Mac OS compatibility with either/both Logic Pro and the Dolby Atmos renderer was a 'thing' but that may have changed.
For OS compatibility (only) discussion I found this

One of the most difficult pieces of the Atmos music production puzzle is the notion of a 'monitor controller' that can handle the volume and speaker crossover eq for playback.
Again, most of the dedicated solutions are expensive and not too long ago there were very few that combined an audio interface with the controller.
Here is an example discussion of making use of a reasonably priced solution from not too long ago.
I've been thinking of trying to use an AV receiver as a poor man's monitor controller.
If you're just doing things 'inside the box' ex all recorded tracks from a synthesizer it's much easier but unfortunately I want to record real drums etc which requires a bunch of mics and analog ins and outs etc.
Anyway, glad to see discussion of this here.
