Finest and Precise Audio Systems
Audio processors with carefully designed circuit stages and physical emulation of legacy and modern components: vacuum tubes, transformers, and other passive, digital and nonlinear elements.
In stock
VST3 for 64-bit Windows. A macOS version is coming soon.
Vari-Mu Compressor / Limiter
VariOhmAnalog glue. Musical control.
Push-pull 6BA6 cell
Remote-cutoff pentodes in triode connection, fitted to the datasheet, with a saturating output transformer and a vacuum-rectifier sidechain.
True VU metering
0 VU sits at −9 dBFS, switchable between gain reduction, input and output — with a VU SPEED control for when the needle is too slow for drums.
Stereo, Mid/Side or Mono
Real routing with an external side-chain input, and parallel compression per channel.
Tube Harmonic Exciter
ZenTubeAnalog warmth. Harmonic precision.
Wave-digital 5670 triode
Modelled at 4× oversampling per channel, so the harmonic content comes from the circuit itself.
You can see what it does
A live drawer with the waveform, the harmonic spectrum in dBFS and the in → out transfer curve.
Cathode bias on hand
250–800 Ω moves the triode operating point and rebalances even against odd harmonics.
More than words… and nostalgia
We build audio processors from carefully designed circuit stages and physical models of classic and modern components, including vacuum tubes, transformers, and other passive and nonlinear elements.
Our aim is to design processors that sound good and work well. We combine today's technology with classic tube and solid-state techniques to create new systems, rather than making yet another emulation of old gear. We value what those circuits can teach us, but we want to take their ideas further.
- SEP 2026ZenTube 1.1.0
Preset browser, ABOUT panel and packaging
Preset browser arrows fixed — they were drawn pointing the wrong way. New ABOUT panel with the credits on the bottom strip. Plug-in, installer and wizard now all report the same version, and the installer keeps its report with your plug-in data instead of dropping it on the Desktop.
- SEP 2026VariOhm 1.1.0
Click-free Asymmetry and panel rework
ASYMMETRY no longer clicks when you move it, with or without signal running: the control is ramped sample by sample inside the engine. Typography and the size of the screw-style trim controls reworked across the panel, plus the new ABOUT panel and the same packaging fix.
- AUG 2026ZenTube 1.0.0
First release
The 5670 dual triode exciter ships: wave-digital model at 4× oversampling, with the live analysis drawer.
- JUL 2026VariOhm 1.0.0
First release
The vari-mu compressor / limiter ships, with the dependency troubleshooting wizard launcher for the 64-bit build so Windows installs go through cleanly.
Engineering
Built on practical and theoretical foundations.
Every DSP.Erience audio processor is designed using the responses of carefully selected audio circuits and algorithms across the analog, solid-state, and digital domains. We emphasize circuit theory, physical modeling, acoustic and psychoacoustic principles.
Rather than relying on simple waveshaping or approximations of response curves, we study and develop electronic circuits, apply modern circuit synthesis techniques, and evaluate new and old schematics in light of sound quality and the demands of modern audio and music production.
/01
Modern technology, new methods.
Modern communication and DSP technologies open up new methods for emulating nonlinear components, including vacuum tubes such as the 6BA6 and 5670, vacuum diodes, and transformers.
/02
Clean components.
Some audio hardware emulations introduce poorly defined noise, distortion, and nonlinear behavior to achieve a “vintage” sound or add more “warmth.” This can make it difficult to understand what is happening to the signal and limit meaningful control over the processor’s parameters.
/03
New designs.
Thousands of emulations of classic equipment already exist. Our purpose is to explore new ways of using classic and modern audio technologies in both algorithmic and hardware design, going beyond another imitation.
/04
Careful level calibration.
Carefully calibrated levels provide precise control over gain staging throughout the signal chain.
