Open it up.
Every Kelvinmoor plugin is laid out the same way: presets, compare and SCAN on top, the instrument in the middle, your levels at the bottom. Underneath, a circuit model, not a static curve.

What the plugins do, how SCAN listens, and why every number on screen is there for a reason.
A second pair of ears.
Press SCAN and play the track. It listens for a few seconds, measures what an engineer would measure, and proposes a starting point you apply with one click.
Every move comes with its reason, in one line. You can keep it, change it, or ignore it. It is a starting point, not a verdict.

The catalog.
Twelve single plugins and eight suites. Each one does a job you already know, with SCAN on the front.
Heritage
Light porcelain fronts, black knobs, needle meters. The circuits that made records sound like records: optical, FET, VCA, tape and tube.
Precision
Black glass and live curves. Instruments for the work you have to see to get right: dynamic EQ, true-peak limiting, de-essing, resonances, pitch, space.
