Upward mastering compressor: lifts the quiet, leaves the peaks.
Magnitude is an upward compressor for mastering. Instead of pushing the peaks down, it raises the low-level detail underneath them, so you get density without pumping.
It descends from PRESSURE, the 2006 plug-in by Tom & Jeremy Gersic, and was rebuilt in Rust with look-ahead, colour, sidechain HPF and an HQ mode.
“It lifts the quiet. It leaves the loud alone.”
Test it. Break it. Fix it. Pull requests welcome.
