The science of sound
Opal's journey began with a relentless pursuit of authenticity. Our team employed advanced physical modeling techniques to capture the essence of these renowned optical compressors, creating our own innovative model that is truthful to the original hardware.

By meticulously studying the original hardware units and leveraging the principles of port-Hamiltonian systems theory, we unraveled the intricate program-dependent dynamics and nonlinearities that define the optical compressor’s iconic sound. This rigorous approach ensured unparalleled accuracy and a faithful representation of the vintage hardware.

Advanced modeling
The heart of Opal lies in its precise modeling process. We meticulously measured and analyzed seven distinct hardware units, each sourced from a celebrated studio in an iconic city. By examining each circuit stage we were able to isolate the characteristics that give these units their unique sonic personality.

Through a combination of nonlinear programming and reverse engineering, we carefully calibrated our models to match the behavior of these revered hardware units. Unlocking the specific dynamic characteristics of each optical cell allowed us to reproduce their behavior with astonishing fidelity.

Performance, optimized
To achieve real-time usability without compromising on authenticity, we employed innovative reduction and pre-resolution techniques. Our model, based on the rigorous analysis of circuit schematics and direct measurements, was carefully streamlined to maintain computational efficiency while preserving the intricate interplay of components.

Through skillful simplifications and expert craftsmanship, we condensed the complexity of the original circuit into a robust and efficient simulation. The result is a faithful reproduction of each compressor’s dynamic characteristics that responds with lightning-fast precision, empowering you with both unmatched realism and efficient performance.

Modern features
Opal includes a range of modern features that expand the compressor’s sonic possibilities, and enhance the user experience. From the responsiveness of the optical cell to the versatility of sidechain input, you’ll find a wealth of useful tools at your fingertips.

Take advantage of the advanced makeup drive, frequency response correction, and external sidechain capabilities to tailor your compression with precision.

Faithful emulation, modernized features
The result is a vintage-inspired compressor that seamlessly integrates into modern workflows, firmly delivering the best of both worlds.
