Sonnox Oxford Limiter

Active

Overview

The Sonnox Oxford Limiter is an audio plugin for peak limiting and loudness control in digital audio workstations. It processes audio through pre-gain control, enhancement with overshoot protection, reconstruction metering and compensation, and dithering with noise shaping. Designed for mastering engineers and producers, it supports transparent level control, loudness maximization, and creative effects while conforming to ITU-R BS.1770-4 true peak standards.124

Key Features

  • Peak limiting - Provides attack, release, and variable soft-knee controls for limiting peaks.
  • Enhance section - Increases perceived loudness and detail while preserving clarity.
  • Recon meter - Displays actual signal rather than sampled peaks for accurate metering.
  • Auto Comp - Corrects reconstruction errors without losing overall loudness, meeting ITU-R BS.1770-4 standards.
  • TPDF dither - Auditions and applies dither for 24-bit and 16-bit outputs with four noise shaping types.
  • Noise shaping modes - Four variable-strength modes for dynamic program material.
  • Adaptive timing - Uses look-ahead for precise control in transparent or heavy limiting.
  • Factory presets - Includes library of presets for various starting points.
