Looks like finally they are doign something as there is a new Dolby Atmos Renderer 5.0 which looks to more or less replace the DAPS and it DOES run on Windows, as well as Mac.
If you wanted to create MP4s, you had to have a Mac or go pay Amazon to rent conversion from AWS.
So I have complained, in several other threads, that you couldn’t get the Dolby Atmos Production Suite for Windows.
