It adapts to every take. You make the call.
Adaptive audio plugins that read the signal in real time and tune themselves to it, so one intuitive control does what used to take an afternoon of settings. Human engineering, supported by adaptive technology.
The approach
Deep tech, analog soul.
Under the hood, adaptive AI: deep learning, neural models, and real-time sound analysis. On the surface, analog warmth and character. And in every detail, the care of people who take real pride in the work.
AI that listens, in real time
Deep-learning classifiers and live sound analysis read what is actually in the signal, the phoneme, the voice, the room, and adapt to it, so one intuitive control is all you touch.
Analog warmth, on purpose
Modelled saturation and tube and tape textures give the result character, not just correction, and leave room to be creative rather than clinical.
Made with obsessive care
Every meter shows something real, and every number is measured on real material. We build these the way we would want them built for us.
The Clarity Series
Two plugins for the voice.
Sibilance removes sibilance. Thunder Clarity separates a voice from the room it was recorded in. Each one touches only what you point it at.

Sibilance
Built & validatedA level-independent de-esser. It cuts harsh sibilance by about 5 dB and holds the rest of the band within ±0.04 dB. An analog finish stage is optional.

Thunder Clarity
Coming soonNeural voice separation. It splits the voice, its reverb tail, and the room onto three faders, using a classic STFT engine or a DeepFilterNet core at −34 dB.
Explore Thunder ClarityThe engineering
Three lanes. No lane decides alone.
The de-ess decision runs through three dissimilar lanes, the command-and-monitor pattern from flight-control computers. No single lane fault can cause a wrong cut.
Measures sibilant energy per block. Fast and deterministic, but it can’t tell an “s” from a plosive, so it never decides what a sound is.
Classifies the sound. It can veto the cut to protect a plosive or fricative, but it can never trigger one.
Requires the veto to hold across consecutive windows, so one wrong frame can’t trip protection or flash a false letter on the meter.
Measured, never faked
Measured on real vocals.
Validated end to end on real vocal recordings, not synthetic test signals, which would let us print kinder numbers than these.
