Output level vs. frequency.

It shapes your tone by up to ±1.5 dB on purpose — that built-in curve is part of its sound.

THD   THD+N. THD is the trustworthy figure; THD+N is method-floor-limited at low levels.

It adds a little harmonic color (0.03% at full level) — a gentle warming.

Its own background hiss is below what the bench can even measure, so it adds no noise you would hear.

How hard you push it changes what it does (a -116 dB gap between levels) — expected for a saturator, which reacts to input level.

It delays the audio by 32 samples (0.7 ms at 48 kHz) and reports that delay, so your DAW lines it back up.


What these measurements mean

read from the numbers above · character / coloring design

On the bench it behaves like a coloring tool, scoring 10.0/10 on how clean its signal path is; its tone-shaping and harmonics are reported as character, not graded as faults. It shapes your tone by up to ±1.5 dB on purpose — that built-in curve is part of its sound. It adds a little harmonic color (0.03% at full level) — a gentle warming.

Measured score 10.0/10 — signal-path noise floor (the shaping and harmonics are the design's intent, shown as character, not graded). How scoring works.


What people report

sourced sentiment · in our words, not a bench measurement
8.2/10 published & press sentiment, 4 sources · a separate figure from the measured score

Consistently praised

  • Rated the most characterful of Arturia's three compressor models, with a valve tone that adds body and air to bass and vocals.
  • Easily nudged into gentle saturation that thickens low-mid sources such as 808-style drums and synth bass.
  • Simple, faithful controls plus modern extras like sidechain filtering and mid/side detection.

Common criticism

  • The least flexible of the set, with a non-linear attack and release that suit some material more than others.
  • Like its siblings, it lands in an already-full market of vintage compressor emulations.

A review score is shown only when at least two independent sources — published reviews or genuine user discussion — return usable text. Launch or announcement coverage alone does not qualify, so some plugins read N/A here while still carrying a full measured score above.
