Where to get itAvailable from Sonnoxsonnox.com

Oxford SuprEsser is a professional de-esser and frequency-specific dynamic EQ plugin designed to transparently control aggressive frequencies in vocals and instruments. At its core, it isolates problematic frequency bands with linear-phase filters and applies surgical compression only to those bands, leaving the rest of the spectrum untouched. What makes it distinctive is its automatic level-tracking that adjusts the threshold to follow the signal's general level, eliminating manual automation, plus advanced modes that function as a full-featured compressor for creative and corrective work across the entire frequency spectrum.

Key Features

01Linear-phase bandpass and band-reject filter pair with automatic switching to High-Q Notch, LF-Cut, and HF-Cut modes
02Automatic level-tracking with 24 dB working range and settable after-silence start level
03Four trigger and gain-ducking modes: Band-Band, Band-Wide, Wide-Band, and Wide-Wide
04Three listen modes: Mix, Inside, and Outside for intuitive frequency isolation
05Advanced dynamics with ratio control from 1:1 to Inf:1 to -2.5:1, soft knee up to 20 dB, and wet/dry blend
06FFT graphical display with peak-hold frequency and real-time gain reduction visualization
07Three kernel size versions: Standard (2048 samples), HR/HighRes (8192 samples), and LL/LowLatency (512 samples)
08Support for 20 Hz to 20 kHz frequency range with width control from 0.2 to 10 octaves

Things to Try

  • 01Enable Auto-Level-Tracking mode and bring the threshold down until gain reduction begins, allowing the plugin to automatically adapt as vocal levels change between verse and chorus
  • 02Use INSIDE listen mode to isolate the troublesome frequency band, then sweep the center frequency to quickly locate sibilance peaks and home in on specific consonants
  • 03Click on the red peak frequency marker in the graphical display to instantly center the band filter on the frequency with the highest energy
  • 04Set Width to 0.2 octaves to activate High-Q Notch mode for extremely narrow frequency reduction, such as isolating a single whistle frequency
