OD Limen – named after the Latin word for “threshold” – is a high-frequency acceleration limiter designed for mixing and mastering. Rather than limiting the full signal, Limen isolates and processes only the high-frequency content above a user-defined crossover point:

  • Depth controls the intensity of the limiting process, from subtle taming to aggressive control.
  • Crossover sets the split point using a linear-phase filter with adaptive slope for perfect signal reconstruction.
  • Tilt shapes the spectral balance of what the limiter sees, controlling the focus between low and high frequencies.
  • Recover preserves your tonal balance – ensuring Limen only affects the dynamics, not the character of your sound. Values above 100% add a silky high-frequency quality that conventional EQ cannot achieve.

Traditional high-frequency limiters rely on a fixed threshold and require careful calibration to match the input level. Limen instead responds to high-frequency acceleration directly, adapting automatically to any input level. The processor features Focus Listen for soloing individual frequency bands, an external sidechain input, configurable keyboard shortcuts, and flexible L/R or M/S channel processing.

Ohlhorst Digital is a brand by Jan Ohlhorst. Initially developed exclusively for his work as a mastering engineer, these well refined products are now being made publicly accessible.

It's LIKE a transient shaper, it's LIKE a de-esser, it's LIKE a HF roll-off — but it sounds so NATURAL. It's like running through tape. Silky smooth highs — harshness bye bye. Not like more or less highs — more like 'how soft do you want the snare and cymbals to sound?' All that while still being open and not dull.

Limen is just an incredibly nuanced transient shaper — everything can be controlled so precisely but feels so effortless. All of your plugins are world class in form and function, really a high water mark in digital processors. The whole Ohlhorst Digital suite makes formerly opaque and complex tasks seem easy yet precise.
