Output level vs. frequency.

It leaves your tone flat (within ±0.13 dB); the color here comes from added harmonics, not from EQ.

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

It adds clear harmonic color (2.7% at full level) — the grit and warmth this design is meant to give.

Background hiss sits at -117 dBFS — quiet in normal use.

How hard you push it changes what it does (a -45 dB gap between levels) — expected for a saturator, which reacts to input level.

It delays the audio by 4 samples (0.1 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 9.2/10 on how clean its signal path is; its tone-shaping and harmonics are reported as character, not graded as faults. It leaves your tone flat (within ±0.13 dB); the color here comes from added harmonics, not from EQ.

Measured score 9.2/10 — 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.
