Measured.
Not modeled.

Mixing and measurement plug-ins held to a laboratory standard. Every curve is checked against its definition, every claim on this page was measured on the built plug-in, and anything we don't process leaves exactly as it came in.

The rules every Dogma plug-in follows

The Dogma

01

Untouched means bit-exact

Below threshold, in bypass, at unity: the output is the input, bit for bit, in 32 and 64-bit hosts.

02

The curve is the definition

One formula in the DSP, the tests and the display. We publish how far the built plug-in is from it, in dB.

03

Same bits everywhere

Our own deterministic math, fixed summation order, golden test vectors on every build. Any block size, any OS.

04

Nothing between you and the sound

No dongle, no account, no online check. Install it and it runs.

Dogma QAnalog-matched equalizer

A 24-band parametric EQ whose every band follows its analog prototype all the way to 20 kHz — with no latency. Where an ordinary digital EQ bends near the top of the spectrum, Dogma Q stays on the curve.

Each band is redesigned in real time — in about 65 µs — every time you move it, so the Q is truly free and the curve never cramps near Nyquist. The default mode adds no latency at all; Natural Phase matches the analog phase as well, within a thousandth of a degree; Linear Phase removes phase shift completely. Everything runs in 64-bit, automation is sample-accurate, and bypass is bit-exact.

Dogma CLab-precision compressor

The audio path is a single multiplication: no filter, no delay, no phase shift — only gain. The static curve, the attack and the release do exactly what their knobs say, and you can choose how close to a continuous-time compressor you want to get.

Attack and release are real time constants: after one τ, exactly 63.2 % of the step is done, at every sample rate. The Peak detector holds its value for 25 ms, so a steady bass note is read as a steady level and the gain doesn't wobble inside the waveform. Lab mode runs the sidechain at about 384 kHz; Reference and Ideal solve the compressor between the samples. In every mode, nothing but gain touches your audio.

Dogma DESLab-precision de-esser

What isn't taken comes out exactly as it went in. Dogma DES only ever adds the difference it removes, so between the S's your vocal is untouched — bit for bit. In Relative mode the reduction is the same on a whispered take and a shouted one.

The key and the band are the exact responses of their analog prototypes, not bilinear approximations that drift by several dB near the top. The envelope comes from a quadrature pair accurate to millionths of a degree, so a sibilant is read at its true level whatever its phase. Choose Wide for the whole signal, HF Only for a bump-free shelf above the split, or Band for a dynamic bell — and listen to the key or to exactly what's being removed.

Dogma IR-REVConvolution reverb

Real spaces at zero latency. Load an impulse response — a hall, a plate, a room you captured yourself — then reshape it: its onset, its length, how each frequency band decays, where it sits in the stereo field.

The convolution engine is non-uniformly partitioned: a short head on the audio thread and a long tail in the background, so even a ten-second IR plays at zero latency. Shaping happens in a second layer that rebuilds the impulse while you play and morphs to it smoothly — onset, hold, shape, length, a three-band crossover decay. Around it: an analog-matched high shelf, a three-band EQ, stereo image tools and two delays with band-limited fractional timing.

Dogma IR-CImpulse-response capture

Measure any room, cabinet or piece of hardware and turn it into an impulse response ready for Dogma IR-REV. Three steps — Level Check, Measure, Load in Reverb — with the measurement science of an acoustics lab underneath.

Under the guided three steps is a measurement chain from the acoustics literature: a synchronized swept sine, spectral deconvolution with frequency-dependent regularization, harmonics two to five split off so the linear IR is free of distortion, clock-drift correction between devices, a loopback reference for your converters, and Lundeby truncation of the tail. The result is a ready IR for Dogma IR-REV plus a full ISO 3382 report — or an average of several positions with confidence intervals.

FAQ

Do I need an iLok?

No. Dogma plug-ins don't use dongles, accounts or online checks. AAX builds are code-signed so Pro Tools loads them, and that's all.

What does "lab precision" actually mean?

Each plug-in has a mathematical definition — the analog prototype of an EQ band, the static curve of a compressor. We measure the built plug-in against that definition at every sample rate and publish the gap in dB. Where a plug-in doesn't process, its output is the input, bit for bit. See the measured numbers.

Which formats and systems are supported?

Every plug-in, on Windows and macOS (11 or later, Apple Silicon and Intel): VST3, AAX (Pro Tools), CLAP and a standalone app, plus AU on the Mac. See the table above.

How do I join the beta?
