I am not using the Sounsend app so I can’t say. I am not sure it even has room correction.
When using the Platin Surround hub, there is a Platin generic app that can be used for this purpose, or any of the apps from other manufacturers that rely on Platin hubs (like Buchardt, System Audio, Econic). They all work. It’s basically the same app for all of them, just the logos are different.
But then again, you need a Platin Audio hub for that, not Soundsend.
