I did miss it.

I must confess to being highly suspicious of using DSP for anything
that changes the input waveform in an audible way. (Using it to
produce a more accurate representation of the original sound is a
different issue.) How can a DSP system compensate for problems like
standing waves, where the sound can vary considerably in different
parts of the room?

Imperfectly but better than not. As I hope I implied strongly enough,
it is always better to improve the acoustics with physical correction.
However, (1) there are limits to what can be achieved in common
domestic situations and (2) there are situations where none are
tolerated. In those cases, careful use of DSP eq can be a significant
improvement despite changing "the input waveform in an audible way."
Not panacea.
