Description

The Sonnox Oxford SuprEsser is an advanced de-essing tool tailored for professional audio engineers seeking precise control over sibilance and harshness in vocal and instrument tracks. Unlike traditional de-essers, the SuprEsser offers detailed frequency targeting, allowing users to isolate problematic frequencies with pinpoint accuracy, ensuring natural, transparent results.

Equipped with intelligent detection and a real-time visual feedback interface, the Oxford SuprEsser lets you see exactly where and how sibilant sounds are affecting your audio. The intuitive design and graphical EQ allow for effortless tweaking, making it easy to apply selective compression only where needed, preserving the integrity of your sound. Ideal for music production, podcasting, and post-production, the SuprEsser is trusted by industry professionals worldwide for its versatility and high-quality output, helping users achieve polished, professional results with ease.

With its unique ability to shape, refine, and enhance the clarity of any track, the Sonnox Oxford SuprEsser is the essential tool for anyone looking to elevate their sound and overcome the common challenges of vocal harshness and sibilance control in audio production.

The SuprEsser Difference - More Than Just De-Essing

Oxford SuprEsser plugin
The Oxford SuprEsser goes beyond standard de-essing—it’s a dynamic frequency control powerhouse. Whether you’re smoothing sibilant vocals, controlling harsh instrument tones, or tightening the low-end, SuprEsser works dynamically, only reducing problem frequencies when necessary while leaving the rest of your mix untouched.

What sets SuprEsser apart is its flexibility—three distinct plugins for specific tasks, a floating threshold that adapts to performance dynamics, and precise control over the full frequency range, from 20Hz to 20kHz.

Three Separate Plugins for Total Flexibility

    Low Latency

    Ideal for live tracking or real-time work where fast, efficient frequency control is crucial, with minimal delay.

  • Weighing scales icon

    Standard

    Perfect for mixing, balancing speed and precision to handle common frequency issues in everyday studio work.

  • Microscope icon

    High Resolution

Floating Threshold for Automatic Level Tracking

Working with a vocalist who moves from soft, breathy whispers to full-throttle screams? A static threshold won’t cut it. That’s why SuprEsser’s floating threshold automatically adapts to your performance’s dynamic range. Whether your singer is barely whispering or belting out, SuprEsser ensures smooth, transparent de-essing and frequency management—no manual adjustments required. This means consistent control, even with the most extreme dynamic shifts.

Precision. Flexibility. Control.

The Oxford SuprEsser isn’t just a de-esser—it’s a complete dynamic frequency control tool. Whether you’re working on vocals, instruments, or full mixes, SuprEsser’s depth of control, floating threshold, and three specialised plugins give you everything you need to tackle any frequency challenge at any stage of production.

The Sonnox Oxford SuprEsser isn't just a good de-esser, it is an exceptional one. SoundOnSound
