You know something is wrong - but not what
Engineer Factory goes through every track on its own and then the whole mix. What you get back is not a hunch but a list: this is too loud, this booms at 240 Hz, this disappears on a phone.
- Is my mix loud enough for Spotify?
- Why does it sound thin on a phone?
- Which tracks are fighting each other?
- Where is it clipping without me hearing it?
