AB:X, in brief.

In one line

AB:X is the stem mixer for iPhone that answers one question, wherever you listen: is it better?

In a paragraph

Export your stems, open the folder in AB:X and take the mix wherever it will be judged: the car, the couch, the train, the walk. Up to 32 stems play together, each with its own level and four-band EQ. One key puts your mix against a reference, or against itself without your changes, while it plays. A reference runs on its own transport, the Lattice shows where every stem sits, and version compare picks between finished mixes blind. When you're done, export the mix with a notes file of every change for your DAW.
