Hmmmmm...I would not be at all surprised if what Surround: AI does is rob power from one channel to support another. It would do this by analyzing dynamics and ensuring those dynamics are preserved while less dynamic channels are sacrificed. I worked on something like this 18 years ago. We called it Dynamic Power Allocation. I should have called it DynaPower: AI. Missed my chance.
