Gravitywell · Compressor
Compression you can see gripping the signal.
The transfer curve is drawn live, with your signal’s energy piled up behind it. Set the threshold against what is actually there — then watch the curve take hold.
- In development
- macOS
- AU + VST3
- $119 launch price
Reference render — Sonaurelis Visual Standard v2.0
- Threshold and knee are handles on the curve itself
- Your input’s energy histogram sits behind the transfer curve
- Live gain-reduction ribbon and envelope history
- Delta and sidechain listen, one click each
The hero display
Set the threshold where the music actually is
Level in against level out, on a calibrated −60…0 dB grid. Threshold and knee are handles that live on the curve — you drag the compression, not a knob that stands for it. Behind the curve, a histogram of your input’s real energy shows where the signal lives, so the threshold lands on the music instead of a guess.
A gold gain-reduction ribbon runs across the top, an envelope history strip along the bottom, and hovering any level reads out in → out in dB — computed by the compressor’s own detector, never interpolated for show.
Beneath the display, the audition rail keeps judgment one click away:
- Bypass
- Delta
- SC Listen
- HQ

Feel-first macros
Eight controls by default
Five macros carry the whole plugin, labeled by feel at the arc ends. The exact value lives in the chip beneath each knob; double-click and type, units understood.

-
SoftFirm
Control
How much the compressor works overall. More Control grips the signal harder and evens out the level — reach for it first when a part won’t stay put.
-
RoundSharp
Transient
The front edge of each hit. Toward Sharp the attack snaps through; toward Round it tucks in. For drums that feel blunted or spiky.
-
TightFull
Sustain
What happens after the hit. Toward Full, tails and room bloom forward; toward Tight they close down — pull a performance closer or push it back.
-
LeanHeavy
Weight
The center of gravity of the sound. Toward Heavy the low-mid body thickens; toward Lean it clears out. For a bus that feels thin or muddy.
-
CleanColored
Character
The unit’s color. Toward Colored you hear gentle harmonic thickening on loud moments; Clean stays transparent — glue you can hear.
The expert drawer
Attack, release, and the rest — one key away
Press E and the full plugin slides out — Detector (attack · release · lookahead), Transfer (threshold · ratio · knee), Sidechain (SC high-pass · SC tilt · stereo link) — each parameter a knob with its exact value in a chip beneath it. The macro band and meters stay live while it is open.
Hidden, never removed: every parameter stays automatable and preset-addressable whether the drawer is open or closed.
- Detect RMS/Peak
- Auto Gain
- Ext SC

Presets
A browser built for audition
Previous and next audition a preset in one click. In the dropdown, arrow keys audition as the selection moves — you hear each preset the moment it is highlighted. A gold dot marks state that differs from the saved preset, computed from a real comparison of the state, never a heuristic.

Truthful by construction
Gain reduction, properly calibrated
The signal rail keeps Mix at the top — a suite rule — over calibrated in/out meters and a dedicated gain-reduction rail: 0 / −6 / −12 / −24 dB, filling downward, with a live numeric readout. Fast attack, smooth release, 60 fps.
Suite-wide rule: every moving pixel traces to real telemetry from the plugin’s own DSP. No decorative spectra, no idle animation imitating signal. When nothing plays, the displays hold their calibrated scales at rest — never a synthetic waveform.
