Output level vs. frequency.

It shapes your tone by up to ±2.1 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 heavy harmonic color (10% at full level) — strong, deliberate character.

Background hiss sits at -166 dBFS — far quieter than anything you would hear in a mix.

How hard you push it changes what it does (a -55 dB gap between levels) — expected for a saturator, which reacts to input level.

It delays the audio by 36 samples (0.8 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 ±2.1 dB on purpose — that built-in curve is part of its sound. It adds heavy harmonic color (10% at full level) — strong, deliberate character.

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 · separate from the measured score
N/A No review score yet · not enough independent review coverage to report

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.
