I’ve engineered a suite of mastering‑grade plugins built from the same DSP principles I rely on in my own studio: precision algorithms, transparent processing, and behaviour modelled on real‑world mastering workflows.
Designed by mastering engineer Andy De Rosa, these plugins were created to solve genuine production and mastering challenges using the same principles and workflows trusted in professional mastering environments.
Whether you're producing, mixing, or mastering, every plugin is designed to help you achieve more confident, more musical results without sacrificing translation, clarity, or technical accuracy.
Most audio plugins are designed to impress during a quick demo.
These tools were designed to perform when your music matters most.
Every processor has been built around one simple philosophy:
Enhance the music. Preserve the integrity of the mix.
That means no gimmicks, no exaggerated processing, and no effects that fall apart when your mix reaches mastering or release stage.
Instead, you'll find carefully engineered DSP designed to deliver reliable, repeatable, professional results across real-world playback systems.
These plugins weren't developed inside a marketing department.
They were designed, tested, and refined using real music, real clients, and real mastering workflows.
Throughout development, the tools were evaluated by experienced mastering engineers, producers, and industry professionals to ensure that every decision served the music rather than simply producing impressive specifications.
The result is a collection of processors that deliver the precision mastering engineers expect, while remaining simple and intuitive for producers and mix engineers.

Give your music greater width, depth and spatial impact whilst keeping your centre image focused, your low end solid, and your mixes translating confidently across every playback system.
Designed by mastering engineer Andy De Rosa, WIDENER delivers mastering-grade stereo enhancement without the phase problems, weak bass, and mono collapse commonly associated with traditional widening plugins.
Most widening plugins sound impressive at first.
Then the problems appear.
WIDENER was developed specifically to avoid these compromises.
Using a carefully engineered hybrid widening approach, it increases perceived width whilst maintaining clarity, punch and mix translation.
The goal isn't simply more width.
The goal is more width you can trust.
What WIDENER Does
WIDENER increases the perceived size and openness of your mixes whilst protecting the elements that matter most:
Whether you're widening synths, enhancing a chorus, improving ambience, or adding subtle width during mastering, WIDENER delivers musical results without introducing unwanted artefacts.
Key Features
* Mastering‑grade widening algorithm — clean, controlled, and phase‑stable
* Mono‑safe low‑end — keeps kick, bass, and fundamentals centred and powerful
* Frequency‑aware expansion — widens the right areas without washing out the mix
* Zero‑latency processing — perfect for tracking, mixing, and live playback
* Ultra‑low CPU load — efficient enough for large sessions
* Simple, producer‑friendly interface — one dial for width, advanced control under the hood
* Cross‑DAW compatibility — VST3 / AU/ AAX for macOS and Windows
Many widening plugins achieve their effect through aggressive phase manipulation.
Whilst this can create an impressive stereo image initially, it often introduces problems that become apparent later:
WIDENER was designed from a mastering perspective.
Its frequency-conscious widening approach allows you to achieve greater spaciousness whilst maintaining the stability and reliability required for professional release-ready productions.
Because wider should never mean weaker.
Perfect For:
* Mix engineers wanting width without losing punch
* Producers wanting bigger choruses, wider synths, and more immersive ambience
* Mastering engineers needing subtle, controlled stereo enhancement
* Anyone tired of wideners that ruin mono compatibility
