AC-4 is (sort of) like Atmos, so, in theory, it
will be possible to leverage and extend any
Atmos support, but as of now there is a dearth
of open source implementation(s).  And while
commercial apps can license the technology
(and the SDK) from Dolby to process the
audio (and some have done so to get things
working) there are only a limited number of
commercial AVRs/TVs with AC-4 support
today, and none of the major OS vendors
have yet shipped native AC-4 processing
capabilities in their own media frameworks to
make processing AC-4 available to apps on
those platforms.  And, as always, Dolby's
technologies are an IP minefield.
