Converting to Atmos?

[KRW1]

As far as I'm aware, Atmos is more than just adding two height channels to an existing soundtrack; object based rather than channel based but what this means in reality, I've no idea.

(I still haven't tried a test)

Perhaps to avoid confusion, does an object based 7.1 mix sound different/better to a channel based 7.1 mix and someone far more able than me needs to answer
