Oxford SuprEsser

The deal

$61 at KVR Marketplace (down from $244). Sale ends July 16, 2026.

What it is

The Oxford SuprEsser is a frequency-conscious dynamics processor from Sonnox that works as both a precision de-esser and a full-spectrum dynamic EQ. It operates across the entire audio range (20Hz-20kHz) using Linear Phase processing, which avoids the phase artifacts common in standard de-essers. Simple and Advanced modes give producers fine-grained control over problem frequencies without coloring the surrounding signal.

Who it's for

Mix engineers and producers who regularly deal with harsh sibilance, brittle high-mids, or any problem frequency that needs dynamic taming rather than a static EQ cut. It excels on vocals, drum overheads, and acoustic instruments where transparent processing matters.

Key features

• Award-winning Linear Phase Dynamic EQ delivers transparent, phase-coherent frequency-specific compression
• Auto Level Tracking automatically adjusts gain reduction relative to signal level changes for consistent results
• Wet/Dry blend control enables parallel processing for natural-sounding dynamics
• FFT display with three listen modes lets you pinpoint and monitor problem frequencies with precision
