@martin-smith For AI based mixing/mastering you probably want to use the industry standards like iZotope Neutron and Ozone. I suggest you try the trial versions of both and check whether they work in Acid 10, because Acid is pretty old by now.

For mastering you can also use the free Matchering (available on Github https://github.com/sergree/matchering ). It's on the same level as Ozone.
