MECHANICAL ACOUSTIC SYNTHESIS
Resonheart mimics a mechanical acoustic laboratory rather than a digital synth. By simulating air pumps and metal resonators, it captures the grit of real-world physics. This creates textures that feel alive, offering an earthy alternative to sterile libraries.
Shape everything from haunting woodwinds to metallic percussion. The engine responds naturally to your performance, allowing you to craft evolving, cinematic timbres that breathe. It’s an essential tool for character-driven sounds.

In a world of sampled libraries that often feel static, Resonheart by Xhun Audio offers something fundamentally different. It isn’t a collection of recordings; it’s a living, breathing mechanical machine built entirely inside your DAW.
Using Advanced Component Simulation (ACS), Xhun Audio has modeled the fluid dynamics of air, the tension of pneumatic valves, and the vibration of metal resonators. The result is an instrument that behaves like an acoustic object. When you play a note, you aren't just triggering a file you're activating a virtual air pump that pushes through modeled valves into a complex block of Helmholtz resonators. This is "steampunk" sound design at its most authentic.
For composers and producers, the challenge is often finding sounds that feel "real" without being clichéd. Resonheart bridges the gap between synthesis and traditional instrumentation. It mimics the physics of woodwinds, membranes, and ethnic strings, yet it retains a supernatural quality that only physical modeling can achieve.
Whether you need a haunting, flute-like lead for a cinematic score, a metallic percussion hit that sounds like it’s made of brass and steam, or an organic pad that shifts like a choir of whistles, Resonheart delivers. It feels tactile, unpredictable in the best ways, and deeply human.
The interface is designed for immediate interaction. Every component from the air pump motors to the turbulence dispersion is laid out on a single-view panel. This isn't about menu diving; it's about turning a knob and hearing the "airflow" change.
The mechanical heart of this plugin is modeled after real-world hardware, including Venturi valves and swing motors, creating a sound that is 100% free of electronic oscillators. Each of the four voices contains sixteen universal Helmholtz resonators, allowing you to tune components individually to craft entirely new acoustic families. Because it simulates physics, the modulations feel natural. The way the pitch follows the air pressure or the way the room acoustics react to the "instrument" body creates a sense of presence that samples simply cannot replicate.
Resonheart usually retails for a premium, reflecting the years of research into fluid dynamics and acoustic physics that went into its creation. For a very limited time, we are offering this unique instrument at an exclusive price.
This is your chance to add a truly "acoustic" synthesizer to your collection one that breathes, vibrates, and reacts just like a physical instrument on a scoring stage. Take advantage of this window to own a piece of high-end physical modeling before the valves close on this deal.
