Warning: Use sparingly. Your final master is loud, but it sounds "dark" compared to commercial tracks. The Fix: On your master bus, before your limiter, insert Fresh Air. Set HIGH to 1.0. Set AIR to 1.5. Set MIX to 20%. This gently lifts the entire mix without introducing the phase issues of a sharp EQ shelf. It creates a "window" for the mix to breathe.
That is exactly why Slate Digital’s is such a useful tool.
