Boutique physical modeling
Real physics.
Not samples.
Reso Audio builds audio plug-ins from the equations that make real instruments ring. Every plate, string, and drum is solved from a physical model, not recorded, so it responds continuously to every velocity and every note.
What we make
Instruments, modeled from first principles.
A sample library plays back what a microphone once captured. A physical model computes the sound as it happens, from the material, the geometry, and the way you strike it. That is the whole difference, and you can hear it the moment you push the dynamics.
Our engines are modal and finite-element solvers written from scratch, shared across the family through one physical-modeling core. The result is a small catalog of focused, honest tools rather than a wall of presets.
The catalog
Choose your resonator.
One physics core, a different instrument on top of it. Start with ResoPlate, our first paid release, or the free Sympiano.
ResoPlate
Four independent modal plates, tuned by real material and geometry. A plate reverb that is solved, not sampled, and never an impulse response.
Sympiano
A piano string-resonance reverb: 230 modeled strings ring in sympathy with your audio. Completely free, and the friendliest way into the family.
Resodrum
A sympathetic drum reverb and a playable, physically modeled drum in one, with a 3D interface you can tune by hand.
ResoCymbal
A physically modeled cymbal with real nonlinear shimmer and chaos, a sound that convolution simply cannot reach.
Why it sounds different
Built on real physics.
Solved, not recorded
Modal and finite-element solvers compute each resonance from material and geometry. Nothing is a stitched-together sample or a static impulse response.
Alive at every velocity
Because the sound is generated in real time, a soft touch and a hard hit are genuinely different events, not two layers crossfaded together.
One honest core
Every plug-in shares a single physical-modeling engine. We ship a few focused instruments we can stand behind, not a catalog padded with presets.
Who is behind it
A small studio with a physics habit.
Reso Audio is the plug-in studio of Benjamin Guerrero, an independent developer and music educator. Boutique by choice: every instrument is built, tested, and supported by one person who cares how it sounds.
