Free plugin · Debut release

ClavoxA neural capture of a blue-stripe FET limiter, set for vocals.

Aggressive FET compression that pushes a vocal to the front of the mix, with the grit of a driven output transformer. We modelled it from one analog unit and packed it into a free plugin. No iLok, no account, no trial.

The Clavox plugin interface: brushed-metal faceplate with Input, Output and Comp Mix knobs, 1×/2×/4× oversampling buttons, an amber VU meter showing gain reduction, and a blue center panel with the Clavox name.

On the faceplate

Five controls. One job.

Input−24 to +24 dB
Drives the model harder. More input means more gain reduction and more transformer grit, just like the hardware.
Output−24 to +24 dB
Makeup gain after the model, so you can match levels and judge the tone instead of the volume.
Comp MixDry 0% – Wet 100%
Built-in parallel compression. Blend the crushed signal under the clean vocal without a send.
Oversampling1× · 2× · 4×
Reduces aliasing from the saturation stage. 4× is recommended for the best results.
MeterGR · In · Out
An amber-lit VU meter, switchable between gain reduction, input and output level.

Recommended setup

For the best results

Session sample rate

44.1 kHz

Clavox’s native rate. The model was trained on 44.1 kHz audio, and that’s where its latency is lowest (0.86 ms). It still runs accurately at every other sample rate, from 48 kHz up to 192 kHz, so you don’t need to change your session to use it.

Oversampling

4×

Set the oversampling buttons to 4× for the cleanest saturation with the least aliasing.

Gain reduction at peaks

≈ 7 dB

With the meter on GR, turn up Input until the vocal’s loudest moments show about 7 dB of gain reduction. That’s where Clavox has the best effect. Then set Output to match the level.

How it’s modeled

Neural capture

01

Captured, not guessed

We ran thousands of test signals and vocal takes through the analog unit at fixed settings (4:1 ratio, attack 3, release 7 (fastest)) and recorded exactly what came out.

02

A network that learns the circuit

A neural network learns how the hardware turns input into output: the FET gain-reduction curve, how it recovers between syllables, and the harmonics added by the output transformer.

03

Lowest latency at 44.1 kHz

In a 44.1 kHz session, the rate the model was trained at, Clavox adds just 38 samples (0.86 ms). At other session rates it adds about 3.1–3.2 ms. Full figures are below.
