WARREN LABS
Two lines · one workshop · public beta

Tools that tell the truth.

Reference, correction, and metering on the Trueness line; color, dirt, space, and motion on the Character line. Built by a headphone-and-studio veteran, shared engine by shared engine. Now in public beta.

Level is a full release. The other eight are paid betas: stable enough to work in, still being voiced. You buy once, and every update through 1.0 is included.

Every plug-in runs in full for 14 days before you buy. Download them here.

Trueness
Level

Headphone correction + crossfeed

Flattens a headphone's measured response by inverting its curve, then adds Bauer-style crossfeed so a mix translates the way speakers would. Every curve says who measured it, and six of them are ours, taken on a rig we own. The signal comes out measurably corrected, honest before anything else.

The bundles
Trueness
The Reference Desk

Everything you need to hear the mix honestly.

Five corrective and diagnostic tools on one shared engine: metering that shows what the low end really does, an EQ and a compressor, a resonance suppressor that also de-esses and de-muds, and a matching EQ that doubles as a translation check.

Beta: includes every update through 1.0

Character
The Character Collection

Heat, motion, and space.

Three colour tools, each covering a whole corner: six saturation models from tube warmth to full fuzz, echo plus chorus/flanger/phaser on one delay core, and a reverb that runs both an FDN and convolution, with synthesized spaces built in and room for your own IRs.

Beta: includes every update through 1.0

The Whole Lab

The Trueness and Character lines, one install.

Level is a full release; the other eight are in beta, and every update through 1.0 is included.

Trueness line
Level's faceplate: response plot, provenance line, output meter, CHECK cluster
The main view. The headphone and where its measurement came from read first, then the curve, then the level it produces.
Level's headphone library with a MEASURED BY column
Every curve says who measured it.
Level with monitoring checks engaged
A latched check is never silent about itself.
Level's output meter showing a latched OVER state
The clip indicator latches until you acknowledge it.

Square's faceplate: goniometer, correlation meter, crossover readout and BASS MONO engaged
The goniometer and correlation meter, with the bass-mono crossover at 120 Hz.
Trueness

Square

Mono-compatibility + phase metering
Make the low end mono-proof.
Beta
Scribe's faceplate: tonal fit curve against a flat-plus-tilt target, with the translation mode row
Match mode against a flat + tilt target. The row along the bottom auditions the same mix on phone, earbuds, laptop and car.
Trueness

Scribe

Matching EQ + mix translation
Scribe a tonal fit to target.
Beta
Pare, full-range resonance suppression
Full range.

Trueness

Pare

Dynamic resonance suppressor + de-esser
Tame what rings, leave the rest.
Beta
Bevel's faceplate: a six-band parametric EQ curve with draggable band handles over a ±12 dB grid
Six bands, dragged straight on the curve. Wheel sets Q, double-click bypasses a band.
Trueness

Bevel

Parametric EQ + analyzer
Ease every band true.
Beta
Brace's faceplate: compression transfer curve with the knee drawn, CLEAN/FET/OPTO models, and the control row
The transfer curve draws the knee as you set it. Here, Clean at 4:1 over a −18 dB threshold, 6 dB knee.
Trueness

Brace

Compressor
Hold the level steady.
Beta
Character line
Temper's faceplate: saturation transfer curve with all six models listed, Tube selected
One saturation engine, six models from Tube through Fuzz. The transfer curve shows what the drive is actually doing.
Character

Temper

Saturation, drive + fuzz
Controlled heat, all the way up.
Beta
Ripple's faceplate: echo train showing decaying taps, Tape character, and the Echo/Chorus/Flanger/Phaser mode row
The echo train draws every tap and its decay. Tape character, and the same delay core runs chorus, flanger and phaser.
Character

Ripple

Echo / delay + modulation
Repeats that ripple out.
Beta
Wake's faceplate: impulse response display with RT60 readout, Hall preset, and the algorithmic/convolution toggle
The impulse response, drawn. ALGO runs the FDN; CONV plays one of six built-in synthesized spaces, or an IR you load yourself.
Character

Wake

Reverb
The space a sound leaves behind.
Beta
Guides

Capturing your own reverb (impulse responses)

Sample the reverb of a real room, your studio or a hall, and load it into a convolution reverb.

Level manual

What every control does, what Safe Gain actually guarantees, and what Level deliberately does not do.

Square manual

Setting a bass-mono crossover, reading the goniometer and correlation meter, and why Square is never quite a wire.

Bevel manual

Editing six bands straight on the plot: drag, wheel, double-click and right-click, and the six filter types.

Brace manual

Clean, FET and Opto, every control, the sidechain filter and external key, and a vocal worked through.

Pare manual

Focus modes, Depth and Threshold, the Delta monitor, and a ringing snare fixed step by step.

Scribe manual

Learning a reference and matching to it, the four translation voicings, and why a fresh Scribe does nothing.

Temper manual

The six saturation models, Bias and the velcro gate, parallel drive, and a bass DI brought forward.

Ripple manual

Echo with tape and BBD character, ping-pong and sync, and the chorus, flanger and phaser modes.

Wake manual

The algorithmic and convolution engines, the six synthesized spaces, loading your own IR, and a vocal plate.
