Character Compressor

Caliper Compressor

Four machines. One sheet of black glass.

Signal path

Why it exists

Change compression behavior without changing the workflow.

FET, Opto, Tube and Clean modes share input, threshold, attack, release, makeup, mix, sidechain high-pass, stereo link and output controls while changing their source-defined response.

Four modes

One control surface, four responses.

01 · FET

FET mode.

FET exposes its ratio choices, including the source-defined All setting, with the shared dynamics controls.

02 · Opto

Opto mode.

Opto uses its own detector and release behavior while retaining the common layout.

03 · Tube

Tube mode.

Tube switches the response and relights the same control surface.

04 · Clean

Clean mode.

Clean supplies the fourth source-defined compressor behavior on the shared panel.

Motion proof

Four modes keep the detector in view.

A deterministic pass through FET, Opto, Tube and Clean shows the history, gain-reduction and level surfaces continuing to respond.

Where it earns its keep

Built for the jobs you actually have.

Mode comparison

Switch compressor behavior while keeping the same gain-staging controls in view.

Parallel compression

Use the shared Mix control to blend the processed and dry paths.

Detector shaping

Use the sidechain high-pass and external sidechain controls where the host supports routing.

Stereo control

Set the source-defined stereo-link control from the same panel.

What's in the unit

Real pixels, not promises.

FET

FET mode exposes its ratios and distinct response on the live panel.

Opto

Opto keeps the controls familiar while changing detector and release behavior.

Tube

Tube supplies a third mode-specific response and light state.

Clean

Clean completes the four-mode set on the same interface.

Questions engineers ask

What are the four modes?

FET, Opto, Tube and Clean.

Which controls are shared?

Input, threshold, attack, release, makeup, mix, sidechain high-pass, stereo link and output remain on the common surface.

What proves that the modes are active?

The interface exposes input/output history, gain reduction and level meters, and the deterministic proof loop shows them moving through all four states.

Harmonic Multiband Compressor

A six-band compressor with five movable crossovers, per-band dynamics, detector or audible input harmonics, and a summed output exciter.

Parametric EQ

Bevel EQ

A freeform parametric EQ with 24 bands, per-band channel placement, dynamic bell and shelf bands, selectable filter slopes, and pre/post analysis.

Algorithmic Reverb

Halo Reverb

A reverb with eight space types, three era choices, six decay bands, predelay, Halo interval voices, freeze, bloom, modulation, ducking and mix controls.

Character Delay

Colonnade Delay

A two-engine delay with Studio, Tape, Bucket and Ghost modes; Dual, Ping-Pong, Serial and Mid-Side routing; and Repitch/Fade and Quartz/Slide behavior choices.

Console Summing System

Iron Summing

A paired Channel and Bus system. Channel instances expose track-side tone and grouping controls; the Bus exposes the summed controls and a registry view of participating instances.

Vocal Chain

Burnish Vocal Chain

A lead-vocal chain in one window: tune, clean, shape, compress, saturate, double, place and ride, each of the eight stages with its own scope. Drop a reference record and the chain proposes settings to sit your voice the way that record sits, showing its reasoning per stage with honest confidence labels. Analysis runs fully local.

Subharmonic Synthesizer

Plinth Subharmonic Synthesizer

A subharmonic synthesizer that finds the fundamentals in your source, generates a sub phase-locked to it, and draws both on one display: the located subharmonics with their readouts and the sub it made. The sub is mono, dead center, and the whole box adds zero latency.

Saturator

Stoke Saturator

A saturator built around one deeply tuned analog-style voice and four knobs. Its weight, punch and loudness behaviour ship as measured contracts: each one is a test that fails the build the moment the number moves. No modes, no styles, nothing to choose.

De-Esser

Chamfer De-Esser

A de-esser that reshapes each ess on its own, tracks the performance level so the de-essing does not change when the singer does, and draws its actual threshold on the display. Click any ess and see exactly what was done to it.

Software Synthesizer

Kiln Synthesizer

A software synthesizer with three oscillator slots, dedicated sub and noise, two filter slots, the Glass modal resonator, a 48-slot modulation matrix and nine effects. Anneal hears a dropped sound and breeds editable patches toward it, fully local.
